FIG. 2 is a block diagram of a traffic-inducing screen control platform according to some embodiments of the present application. As shown in fig. 2, the traffic guidance screen control platform may include a link determination module 210, a link characteristic acquisition module 220, a display content determination module 230, a traffic data acquisition module 240, a display content determination module 250, a display scheme determination module 260, and a display control module 270. In some embodiments, the road segment determining module 210, the road segment characteristic obtaining module 220, the display content determining module 230, the traffic data obtaining module 240, the display content adjusting module 250, the display scheme determining module 260, and the display control module 270 may be included in the traffic induction control platform 110 shown in fig. 1.

The road segment determination module 210 may be configured to determine a road segment on which the traffic guidance screen is located. The road section refers to a traffic line between two adjacent traffic nodes on the traffic network. For example, in an urban road, a road segment may be a road between two adjacent intersections. For another example, in a highway, a segment may be a road between two adjacent nodes (e.g., a roundabout, a fueling station, a service area, a manually set logo). In some embodiments, the road segment determination module 210 may determine the geographic location of the road segment on which the traffic-inducing screen is located. For example, the road section determining module 210 may determine the longitude and latitude of the traffic guidance screen, and query the map data for the road section according to the longitude and latitude. In some embodiments, the relevant operator may manually enter the road segment information for the traffic-inducing screen. In some embodiments, the road segment determination module 210 may automatically determine the road segment on which the traffic guidance screen is located. Specifically, a positioning device may be disposed on the traffic guidance screen, and the positioning device may acquire a geographic position of the traffic guidance screen and send the geographic position information to the road segment determining module 210.

The road segment characteristic obtaining module 220 may be used to obtain road segment characteristics. Different road sections may have different road section characteristics, and if the contents displayed on the traffic guidance screens on different road sections are the same, redundant information may be displayed on the traffic guidance screens on some road sections, while the traffic guidance screens on other road sections lack the display of important contents. In some embodiments, the characteristics of the road segments may include areas where the road segments are located, road classes where the road segments are located, speed limit information, accident rates, surrounding road segments, and/or surrounding venues. In some embodiments, the road segment characteristic acquisition module 220 may acquire road network data and determine road segment characteristics of road segments according to the road network data. The road network data is a network road system composed of roads in a certain area. In some embodiments, the road network data may be obtained by a road segment characteristic acquisition module from a traffic management department and/or other road data providers (e.g., map data providers). In some embodiments, the road segment characteristic obtaining module 220 may determine the area where the road segment is located according to the road network data. In some embodiments, the road section feature obtaining module 220 may determine the road type of the road section according to the road network data. In some embodiments, the road segment feature acquisition module 220 may determine the road class of the road segment according to the road network data. In some embodiments, the road segment characteristic acquisition module 220 may acquire historical traffic data for the road segment and determine the road segment characteristics from the historical traffic data. For example, the historical traffic data may include information of accidents that occurred on road segments over a certain time. The road segment characteristic acquisition module 220 may determine an accident rate on a road segment, etc. from historical traffic data. In some embodiments, the road segment feature acquisition module 220 may acquire the road segment-related image and determine the road segment feature from the road segment-related image. For example, an image acquiring device (e.g., a camera, a video camera, etc.) is disposed on the traffic guidance screen, and may capture a road segment-related image (e.g., a traffic sign disposed on a road segment, etc.) and send the related image to the road segment characteristic acquiring module 220, and the road segment characteristic acquiring module 220 may analyze the received road segment-related image to determine a road segment characteristic. Specifically, the speed limit information, lane information, allowed passage time information, surrounding routes, surrounding venues, and the like of the road section or any combination thereof may be determined from the traffic sign image.

The display content determination module 230 may be used to determine the display content of the traffic guidance screen. For example, the display content determination module 230 may determine the display content of the traffic guidance screen based on the characteristics of the road segment. In some embodiments, the display content may include safety tips information, policy slogan information, holiday consortium information, road conditions information, recommended routes information, and/or milestones information. In some embodiments, the display content determination module 230 may determine the policy slogan information according to the area in which the road segment is located. In some embodiments, the display content determination module 230 may determine the safety prompt information according to the road grade of the road segment, the speed limit information, and/or the accident rate. In some embodiments, the display content determination module 230 may determine the recommended route information according to the surrounding road segments and/or the surrounding stadiums.

The traffic data acquisition module 240 may be used to acquire traffic data. In some embodiments, the traffic data may include any combination of one or more of time data, weather data, road condition data, and/or event data, among others. The time data may include date information and may also include time of day information. The traffic data may include traffic information on the road, etc. The event data may include traffic accidents, vital event information, and the like. In some embodiments, the traffic data acquisition module 240 may acquire traffic data locally. For example, the traffic data acquisition module 230 itself has a timing device for determining time data. In some embodiments, the traffic data acquisition module 230 may acquire traffic data for a particular road segment. In some embodiments, the traffic data acquiring module 230 may acquire traffic data within a certain area and extract traffic data of a specific road segment from the traffic data. In some embodiments, the traffic data module 240 may obtain traffic data from an external database. For example, weather data may be obtained from a weather department, or road condition data and/or event data may be obtained from a traffic management department. In some embodiments, the traffic data acquisition module 240 may acquire traffic data uploaded by the user. The user can upload the traffic data through the user terminal. For example, when the user sees a traffic jam on a certain road section during traveling, the road section information (such as a road section name and/or a road section position) and the traffic jam information can be uploaded. For another example, the user can upload the accident address information and the accident description when seeing that a traffic accident occurs somewhere. In some embodiments, the traffic data acquisition module 240 may acquire real-time acquired traffic data. In some embodiments, the traffic data acquisition module 240 may acquire traffic data once every interval of time. For example, traffic data may be acquired every 2 hours, 1 hour, half hour, 20 minutes, 10 minutes, 5 minutes, 2 minutes, 1 minute, 30 seconds, 10 seconds, 5 seconds, and so forth.

The display content adjustment module 250 may be used to adjust the display content of the traffic guidance screen. In some embodiments, the display content adjustment module 250 may adjust the display content according to the traffic data for the road segment. It should be noted that the display content determining module 230 is mainly used to determine the display content according to the road section characteristics of the road section (the road section characteristics are usually relatively fixed), and the display content adjusting module 250 is mainly used to adjust the display content determined by the display content determining module 230 according to the traffic data (the traffic data is usually constantly changing). For example, the display content adjustment module 250 may adjust the display content according to the time data. In particular, holiday consortium information may be adjusted based on date data. Alternatively, the safety prompt information may be adjusted according to the time data. In some embodiments, the display content adjustment module 250 may adjust the safety prompt information and/or the recommended route information according to the weather data and/or the road condition data. In some embodiments, the display content adjustment module 250 may determine significant event information from the event data. For more explanation on adjusting the display content, reference may be made to fig. 4 and its description.

The display scheme determination module 260 may be used to determine a display scheme of the traffic guidance screen. In some embodiments, the display scheme may include any combination of one or more of display duration, display order, interface layout, and/or display font, among others. In some embodiments, the display scheme determination module 260 may determine the display scheme from the traffic data. For example, the weight of each content in the display content may be determined according to the traffic data, and the display duration, the display order, the interface layout and/or the display font of each content may be determined according to the weight. In some embodiments, display content with higher weight has longer display duration, display ordering is earlier, occupies a prominent position in the interface layout, has larger display font, and so on.

The display control module 270 may be used to control the display content of the traffic guidance screen. In some embodiments, the display control module 270 may control the traffic guidance display to display the adjusted display content according to the determined display scheme. In some embodiments, the display control module 270 may communicate with the traffic induction screen 120 and send the adjusted display content and the determined display scheme to the traffic induction screen 120.

It should be understood that the system and its modules shown in FIG. 2 may be implemented in a variety of ways. For example, in some embodiments, the system and its modules may be implemented in hardware, software, or a combination of software and hardware. Wherein the hardware portion may be implemented using dedicated logic; the software portions may be stored in a memory for execution by a suitable instruction execution system, such as a microprocessor or specially designed hardware. Those skilled in the art will appreciate that the above described methods and systems can be implemented using computer executable instructions and/or embodied in processor control code, such code being provided, for example, on a carrier medium such as a magnetic disk, CD or DVD-ROM, programmable memory such as read only memory (firmware), or a data carrier such as an optical or electronic signal carrier. The system and its modules of the present application may be implemented not only by hardware circuits such as very large scale integrated circuits or gate arrays, semiconductors such as logic chips, transistors, or programmable hardware devices such as field programmable gate arrays, programmable logic devices, etc., but also by software executed by various types of processors, for example, or by a combination of the above hardware circuits and software (e.g., firmware).

The basic information of the traffic guidance screen can comprise information such as number, geographical position, type, working state, setting parameters and the like. The traffic guidance control platform 110 may access the basic information of the traffic guidance screen in the database 140 through the network 130 or update the basic information of the traffic guidance screen stored in the database 140 (e.g., add, delete, and/or change the basic information of the traffic guidance screen, etc.). The update operation may be performed at idle (e.g., zero to four in the morning). The update operation may be performed at intervals (e.g., 30 days, 60 days, 180 days, etc.).

In some embodiments, the relevant operator may manually enter the road segment information for the traffic-inducing screen. For example, the operator may manually input the road section information of the traffic guidance screen in the traffic guidance screen control platform 110. In some embodiments, the road segment determination module 210 may automatically determine the road segment on which the traffic guidance screen is located. Specifically, a positioning device may be disposed on the traffic guidance screen, and the positioning device may obtain a geographic position of the traffic guidance screen and send the geographic position information to the road segment determining module 210.

In some embodiments, the road segment characteristic obtaining module 220 may obtain road network data and determine road segment characteristics of road segments according to the road network data. The road network data is a network road system composed of roads in a certain area. In some embodiments, the road network data may be obtained by a road segment characteristic acquisition module from a traffic management department and/or other road data providers (e.g., a map data provider). In some embodiments, the road network data of the located road segment may include infrastructure information of the road (such as roadbed, road surface, bridge, tunnel, etc.), road accessory facility information (such as toll station, service area, parking area, etc.), and road management information (such as route number, route name, road segment name, management unit, etc.). In some embodiments, the road segment characteristic obtaining module 220 may determine the area where the road segment is located according to the road network data. In some embodiments, the road section feature obtaining module 220 may determine the road type of the road section according to the road network data. In some embodiments, the road segment characteristic obtaining module 220 may determine the road grade of the road segment according to the road network data.

In some embodiments, the road segment feature acquisition module 220 may acquire the road segment-related image and determine the road segment feature from the road segment-related image. For example, an image acquiring device (e.g., a camera, a video camera, etc.) is disposed on the traffic guidance screen, and may capture a road segment-related image (e.g., a traffic sign disposed on a road segment, etc.) and send the related image to the road segment characteristic acquiring module 220, and the road segment characteristic acquiring module 220 may analyze the received road segment-related image to determine a road segment characteristic. Specifically, the speed limit information, the lane information, the allowed travel time information, the surrounding route, the surrounding venue, and the like of the road section or any combination thereof may be determined from the traffic sign image.

In some embodiments, the road segment characteristic acquisition module 220 may acquire historical traffic data for the road segment and determine the road segment characteristics based on the historical traffic data. In some embodiments, the historical traffic data may include any combination of one or more of historical traffic operational data, incidents, historical road network environment, and the like, data parameters (e.g., vehicle numbers, vehicle travel speeds, incident information, infrastructure status, meteorological geological hazards, image video, and the like). For example, historical traffic data may include information about accidents that occurred on road segments over a period of time. The road segment characteristic acquisition module 220 may determine the incidence of accidents on the road segment from historical traffic data. Also for example, historical traffic data may include historical road condition data. Specifically, the historical road condition data may include one or more of historical occupancy of a road segment, traffic flow, vehicle speed, and the like in any combination.

In some embodiments, the historical traffic data may include traffic data acquired over a past period of time by the traffic inducement screen control system 100 via the network 130. The traffic guidance screen control system 100 may transmit the acquired traffic data to a memory internal to the system 100 (e.g., database 140) or an external memory (not shown) for storage. The traffic inducement screen control platform 110 (e.g., the road segment characteristic acquisition module 220) may obtain historical traffic data from the memory. In some embodiments, the historical traffic data may include historical traffic information and/or characteristics for a past period of time (e.g., 6 hours, 12 hours, 1 day, 2 days, 3 days, 5 days, 7 days, 14 days, 1 month, 3 months, etc.). In some embodiments, the historical traffic data may include a number (e.g., 10, 50, 100, etc.) of recently generated historical traffic information and/or characteristics. In some embodiments, the historical traffic data may be traffic information and/or characteristics within an area. The area may include a city, a region, a street, a predetermined area, etc. For further explanation regarding obtaining historical traffic data, reference may be made to fig. 5 and its description.

And 430, determining the display content of the traffic guidance screen according to the road section characteristics. In particular, step 430 may be performed by display content determination module 230. The display content determination module 230 may be used to determine the display content of the traffic guidance screen. In some embodiments, the display content may include safety tips information, policy slogan information, holiday consortium information, road conditions information, recommended routes information, and/or milestones information. In some embodiments, the display content determination module 230 may determine the political slogan information according to the area where the road segment is located. In some embodiments, the area where the road segment is located may include one or more of any combination of provinces, cities, districts, towns, villages and other administrative areas where the road segment is located. The display content determining module 230 may determine the policy label corresponding to the administrative area according to the administrative area where the road segment is located. In some embodiments, the area where the road section is located may be one or any combination of urban central areas, industrial development areas, minority residential areas, and the like. Specifically, when the area where the road segment is located is an urban central zone, the policy token may be various. When the area where the path is located is an industry development area, the display content determination module 230 may determine a policy slogan that encourages development of the relevant industry. When the area where the road segment is located is the minority congregation area, the display content determination module 230 may determine the policy slogan related to the ethnic congregation. In some embodiments, the display content determination module 230 may update the policy slogan at intervals (e.g., 1 day, 7 days, 15 days, 30 days, 90 days, etc.).

In some embodiments, the display content determination module 230 may determine the safety prompt information according to the road grade of the road segment, the speed limit information, and/or the accident rate. The road grade may be determined based on the type of road (e.g., urban road, highway, etc.). The speed limit information may include a sign speed limit, a legal speed limit, and a special time period and weather speed limit. The speed limit of the sign plate refers to the speed marked by a speed limit sign and a marking line arranged on a road. Legal speed limit refers to a road section without a speed limit sign, and the speed limit specified by laws and regulations is required to be obeyed. For example, the high speed limit is generally 110-120 km/h; the speed limit of the first-level highway, such as national road, provincial road and the like, is 80 km/h; the speed limit of the suburban road is 70-80 km/h; the speed of the urban road is limited to 40-60 km/h. The special time limit refers to the limit of the running speed of the vehicle in the special time. For example, when the passenger vehicle is traveling at night (22 hours to the next morning at 5 hours), the speed must not exceed 80% of the daytime speed limit. The weather speed limit refers to the limit on the running speed of a vehicle in special weather. For example, when the vehicle runs on a common road, runs in fog, rain, snow, sand dust and hail, has visibility within 50 meters and runs on ice, snow and muddy roads, the speed limit is 30 kilometers per hour. In some embodiments, the display content determination module 230 may determine the safety tip information for road segments with higher accident rates. For example, for road segments with high accident rates such as consecutive curves, steep slopes, tunnels, bridges, etc., the display content determination module 230 may determine safety prompt information (e.g., "XX ahead, please note safety," where XX may be one or more combinations of consecutive curves, steep slopes, tunnels, bridges, etc.).

In some embodiments, the display content determination module 230 may obtain historical traffic data related to the road segment, and determine the display content of the traffic guidance screen according to the historical traffic data. In some embodiments, the historical traffic data may include historical road condition data and/or historical accident data. In some embodiments, the traffic guidance screen control platform 110 may obtain the traffic data from the database 140 or an external memory (not shown) via the network 130 for a period of time (e.g., 1 day, 7 days, 15 days, 30 days, 90 days, etc.) in the past in the area of the road segment. For example, one or more of the number of traffic accidents (e.g., 0, 1, 5, 10, etc.), accident level (light accident, general accident, major accident, extra-major accident, etc.), congestion situation (no congestion, congestion on the road segment for up to 1 hour, etc.), and other information may be obtained. The area of the road section may include provinces, cities, districts, towns, villages and the like of the road section.

In some embodiments, the display content determination module 230 may determine the display content of the traffic guidance screen according to the surrounding road segments and/or the surrounding stadiums. For example, simple introduction information (such as a road section/venue name, etc.) of a surrounding road section and/or a surrounding venue may be determined as the display content. For another example, the recommended route information may be determined from the surrounding road segments and/or the surrounding venue. Specifically, when the traffic flow of the road segment where the traffic guidance screen is located or a certain road segment around the traffic guidance screen is large, the road segment with the small traffic flow can be determined as the recommended route according to the traffic flow conditions of other road segments around the traffic guidance screen. When a road section congestion is caused by a serious traffic accident on a road section where the traffic guidance screen is located or a certain road section around the traffic guidance screen, and the vehicle is running slowly, the traffic guidance screen control platform 110 can give a detour route according to information of other surrounding road sections. The traffic inducement screen control platform 110 may then save the congestion and recommended route information as historical traffic data in the database 140 or other memory for later analysis (e.g., the historical traffic data may be obtained by the historical traffic data acquisition unit 310). When a surrounding venue (e.g., a sports stadium, a theater, an exhibition hall, a museum, an event center, a mall, a school, etc.) holds an event, a congestion may occur at a surrounding section of the venue, and the display content determination module 230 may determine event information and/or a detour line as display content.

In some embodiments, the display content determination module 230 may analyze historical display content of traffic guidance screens on a number of road segments, and determine display content for a current road segment based thereon. For example, for road segments with similar road segment characteristics, there are often similar traffic inducement requirements, and therefore the same or similar traffic inducement display content may be used for these similar road segments. Specifically, the display content determination module 230 may compare the road segment characteristics of the current road segment with the road segment characteristics of other road segments to determine a similar road segment of the current road segment. The display content determining module 230 may analyze historical display content and generated guidance effect of the traffic guidance screen on the similar road segment, and determine display content with a better guidance effect (for example, reducing an accident rate) as display content of the traffic guidance screen on the current road segment.

And step 440, acquiring traffic data related to the road section where the traffic guidance screen is located. Specifically, step 440 may be performed by the traffic data acquisition module 240. In some embodiments, the traffic data may include one or any combination of time data, weather data, road condition data, and/or event data, among others. In some embodiments, the traffic data acquisition module 240 may acquire real-time traffic information.

In some embodiments, the traffic data acquisition module 240 may acquire traffic data locally. For example, the traffic data acquisition module 230 itself has a timing device for determining time data. In some embodiments, the traffic data acquisition module 240 may access a standard time interface (e.g., a standard beijing time interface) via the network 130 to facilitate a proofing adjustment of the timing device. The timing device can be realized in a hardware mode, a software mode, a hardware + software mode and the like.

In some embodiments, the traffic data acquisition module 240 may acquire traffic data of a road segment on which the traffic guidance screen is located through the network 130. The traffic data may include one or any combination of traffic infrastructure operational data, road network environment data, traffic video image data, traffic operational data (e.g., cross-sectional traffic volume, vehicle category, vehicle speed), traffic incident (block) information, and the like. The infrastructure operation parameters refer to structural stability, technical conditions and the like of major highway infrastructures such as super-large bridges, long and large tunnels and the like. The infrastructure operation parameters can be obtained from highway management departments of various provinces (autonomous regions and direct municipalities), including dynamic health condition grades determined by health monitoring systems or safety early warning systems of bridges and tunnels, technical condition grade parameters of manual detection and evaluation and the like. The cross-sectional traffic volume refers to the number of participants who actually participate in the traffic through a certain cross-section on the road in unit time. The emergency (blocking) event information may include traffic break information and congestion information. Traffic interruption refers to a state in which a road cannot pass or is forced to be closed (for example, measures such as total closing, partial lane closing, time-limited closing, toll station closing, main line diversion, construction suspension and the like are taken for the road) due to some reason. Traffic jam refers to a state that vehicles running on a road are abnormally concentrated or concentrated in a certain section of the road due to certain reasons (including taking control measures such as patrol control, intermittent release, vehicle type limit release, current limit, speed limit release and the like on the vehicles), so that subsequent vehicles drive at a low speed, stop and even stay. The traffic blocking information may include a plan class, a general burst class, and a major burst class. The planned traffic blocking information refers to blocking information that an expressway (including a toll station) needs to be subjected to traffic control or blocking for more than 2 hours or a trunk road such as a national road, a provincial road and the like needs to be subjected to traffic control or blocking for more than 5 hours due to planned events such as highway maintenance construction, reconstruction and extension construction, major social activities and the like. The general sudden traffic interruption refers to an unexpected event caused by a natural disaster (such as a geological disaster, severe weather, etc.), an accident disaster, a public health event, a social security event, etc., and is blocking information that a local section of a highway (including a toll station) is expected to have traffic interruption or blockage for more than 2 hours, or a local section of a trunk road such as a national road and a provincial road is expected to have traffic interruption or blockage for more than 5 hours. The important sudden traffic blocking refers to a local important sudden event which causes serious casualties, influences social public safety and generates bad social influence although long-time traffic interruption or blockage is not caused, or a regional important blocking event which has wide influence range and long duration and causes the traffic interruption or blockage of roads of a plurality of national and provincial trunk lines in a provincial region or a road network crossing the provincial region. The road network environment parameters mainly comprise meteorological data along roads or information shared by related departments such as meteorology, homeland and the like. The meteorological parameters along the road comprise visibility, road surface state (such as dry, wet, ice and snow; temperature), atmospheric temperature and humidity, wind speed, wind direction, rainfall and the like.

In some embodiments, the meteorological environment and disasters shared by the traffic inducing screen control system 100 with the meteorological department may include any combination of one or more of satellite clouds, precipitation scenes, short and medium term weather forecasts, heavy rain, heavy snow, fog , cold tides, strong winds, sand storms, high temperatures, and the like. The geological disaster forecast warning information shared by the traffic guidance screen control system 100 and the homeland department may include one or more of a range, an area, time, a type (such as debris flow, landslide, and the like) of a geological disaster, a falling area map, and the like in any combination.

In some embodiments, road condition monitoring tools (e.g., a ground induction coil, a speed radar, a video capture device, etc.) are installed on the road segment where the traffic guidance screen is located, and the traffic data obtaining module 320 may obtain data measured by the monitoring tools, so as to obtain traffic data. Specifically, the traffic data may include one or more of road occupancy, traffic flow, vehicle speed, and the like in any combination. Data acquisition module 320 may in some embodiments, the traffic data acquisition module 240 may access a traffic big data cloud platform via the network 130 to acquire real-time traffic data. For example, the traffic data acquiring module 240 may access an exit cloud platform (a platform for opening and applying travel data, which is constructed by the department of transportation and by cooperating with a Baidu map) to acquire traffic data. In some embodiments, the traffic data acquisition module 240 may acquire traffic data from a map company (e.g., a high-end map, a Baidu map, etc.). In some embodiments, traffic data may be determined based on data from a large number of GPS devices. For example, a large number of vehicles (such as all taxis in a city) are installed with GPS devices, or a large number of pedestrians carry devices with GPS functions, each GPS device sends GPS data to a monitoring center at intervals (e.g., 10s, 20s, 30s, etc.), and each GPS data includes information of a position, a speed, a moving direction, or the like of the corresponding vehicle or pedestrian. According to a large amount of GPS data, real-time road condition data can be determined.

In some embodiments, the traffic data acquisition module 240 may also be used to acquire historical traffic data for the determined road segments. The traffic data acquisition module 240 may access historical traffic data stored in the database 140 and acquire related data.

And step 450, adjusting the display content of the traffic guidance screen according to the traffic data to obtain the adjusted display content. In particular, step 450 may be performed by display content adjustment module 250. In some embodiments, the display content adjustment module 250 may determine holiday consortium information based on the time data. In some embodiments, the display content adjustment module 250 may adjust the safety notice information and/or the recommended route information according to the weather data and/or the road condition data. In some embodiments, the display content adjustment module 250 may determine significant event information from the event data. For example, the event data may include traffic accident data, and the display content adjusting module 250 may adjust the display content according to the traffic accident data, so that the corresponding accident type, occurrence location, and other information are included in the display content. For another example, the event data may include major event data, and the display content adjusting module 250 may adjust the display content according to the major event data, so that the information such as the event name and the holding place is included in the display content.

In some embodiments, based on the obtained time information, the display content adjusting module 250 may match the obtained date information with preset holiday time information (e.g., preset holiday time information stored in the database 140), and if the matching is successful, retrieve the corresponding holiday consortium information and adjust the display content accordingly. For example, the time information acquired by the traffic data acquisition module 240 is 2018, 4, 17, and if the matching with the holiday time information stored in the database 140 is not successful, holiday consolation information is not output. For another example, the time information acquired by the traffic data acquisition module 240 is 2018, 5/1/h, and if matching with the holiday time information stored in the database 140 and confirming that the date is a holiday date, the corresponding holiday consortium information is determined (for example, "happy five labor festivals, XX traffic police team congratulatory for travel safety", "please tie a seat belt while enjoying holiday happy" and the like).

In some embodiments, the display content adjustment module 250 may extract keywords from the acquired weather data and/or road condition data, and then match the keywords with factors that may affect traffic and are stored in advance (e.g., in the database 140). If the matching is not successful, the factor has no influence on traffic, and the display content is not adjusted. If the matching is successful, the factor possibly has a certain influence on the traffic, the display content is adjusted, and corresponding safety prompt information is called for the influence factor to be displayed. The factors that may have an impact on traffic may include any combination of one or more of road maintenance construction repairs, heavy rain, high winds, lightning, earthquakes, debris flows, traffic accidents, and the like. For example, the safety prompting message may be "construction of a road section ahead, please drive cautiously", "a serious traffic accident occurs on the road section ahead, please detour", and so on. In some embodiments, the display content adjustment module 250 may recommend a route according to the route around the road segment and/or the surrounding venue in the acquired road segment characteristics, because some factors cause a sudden traffic block and need to detour. The display content adjustment module 250 may also retrieve historical recommended routes stored in the database 140 for preferential recommendation.

Step 460, determining the display scheme of the traffic guidance screen according to the traffic data. Specifically, step 460 is performed by display scheme determination module 260. In some embodiments, the display scheme may include any combination of one or more of display duration, display order, interface layout, and/or display font, among others. In some embodiments, the display scheme determination module 260 may determine a weight of each of the adjusted display contents according to the traffic data; in some embodiments, the display scheme determination module 260 may determine the display duration, display order, interface layout, and/or display font of each content according to the weight. The adjusted display content determines the display scheme.

In some embodiments, display parameters such as display duration, display order, interface layout, and/or display font may be adjusted by debugging software in the traffic guidance control platform 110. For example, the display duration may be adjusted by setting the frame attributes. In some embodiments, the display scheme determination module 260 may determine a weight of each of the adjusted display contents according to the traffic data. The weight determination method may include one or any combination of subjective evaluation methods (such as expert survey (Delphi), Analytic Hierarchy Process (AHP), binomial coefficient method, cyclic ratio scoring method, least squares method, etc.), objective evaluation methods (such as principal component analysis, entropy method, dispersion and mean square method, multi-objective planning method, etc.), subjective and objective comprehensive evaluation methods (combined evaluation methods, such as multiplication integration, addition integration, etc.), and the like. The display content adjusted according to the traffic data may include any combination of one or more of time, holiday consolation information, safety prompt information, policy slogan, recommended routes, milestone information, and the like. The display scheme determining module 260 may determine a weight of each display content, and determine a display duration, a display order, an interface layout, and/or a display font of each display content according to the weight. In some embodiments, display content with higher weight has longer display duration, is displayed preferentially, occupies a prominent position in the interface layout, has a larger display font, and the like. In some embodiments, the traffic guidance screen 120 is displayed in a single row, and the display contents may be sequentially displayed in order of decreasing weight according to the weight calculation result. In some embodiments, the traffic-inducing screen 120 is displayed in multiple lines (e.g., 2 lines, 3 lines, 4 lines, etc.), the display content with higher weight values may be centered and displayed in a larger font, and the factors with lower weight values may be displayed in a less prominent (e.g., upper left, lower left, upper right, etc.) position of the traffic-inducing screen 120. For example, the traffic guidance screen 120 may display the date and beijing time in real time at four corners of the screen, such as the upper (lower) left (right). For example, weather information that does not affect real-time traffic or hours into the future (e.g., 1 hour, 2 hours, 3 hours, 5 hours) may be displayed in a smaller font, green, above (below) the left (right) of the traffic-inducing screen 120. In some embodiments, the display scheme may be determined from the temporal data. For example, holiday consortium information may be given higher weight when the time data indicates that it is during holidays. For another example, when the time data indicates a peak in the morning and evening, the traffic information may be given a higher weight. In some embodiments, the display scheme may be determined from weather data. For example, when weather data indicates that the current weather is bad or even bad, the security prompt may be given a higher weight. In some embodiments, the display scheme may be determined based on the traffic data. For example, road condition information and/or recommended route information may be given higher weight when the road condition data indicates congestion in the road segment. In some embodiments, the following calculation formula may be used to calculate the weight of each display content:

wherein, w_iThe combination weight of the ith index; a is_i，b_iRespectively, the objective weight and the subjective weight of the ith attribute. The objective weight can be automatically determined according to a preset weight assignment standard. The subjective weights may be assigned manually by the operator depending on the actual situation.

And 470, controlling the traffic guidance screen to display the adjusted display content according to the display scheme. Specifically, step 470 is performed by display control module 270. In some embodiments, the display control module 270 may communicate with the traffic induction screen 120 and send the adjusted display content and the determined display scheme to the traffic induction screen 120. For example, the display control module 270 may control the traffic induction screen 120 to periodically update the display content.

In some embodiments, the road network data acquisition unit 320 may obtain road network data from a traffic management department and/or other road data providers (e.g., map data providers).

Step 530, obtaining historical traffic data of the road section. Specifically, step 530 is performed by the historical traffic data acquisition unit 310. The historical traffic data may include historical road condition data. Specifically, the historical road condition data may include one or more of historical occupancy of the road segment, traffic flow, vehicle speed, and the like in any combination. In some embodiments, the historical traffic data may include historical accident data. The road segment characteristic acquisition module 220 may determine the incidence of accidents on the road segment from historical accident data.

And 540, determining the road section characteristics of the road sections according to the road network data and/or the historical traffic data. In some embodiments, the road segment characteristic obtaining module 220 may determine the area where the road segment is located according to the road network data.

In some embodiments, the road segment feature acquisition module 220 may acquire the road segment-related image and determine the road segment feature from the road segment-related image. For example, an image acquiring device (e.g., a camera, a video camera, etc.) may be disposed on the traffic guidance screen, and may capture a road segment-related image (e.g., a traffic sign disposed on a road segment, etc.) and transmit the related image to the road network data acquiring unit 320, and the road network data acquiring unit 320 may analyze the received road segment-related image to determine road segment characteristics. Specifically, the speed limit information, the lane information, the allowed travel time information, the surrounding route, the surrounding venue, and the like of the road section or any combination thereof may be determined from the traffic sign image.
