Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example 1
Referring to fig. 1, the invention provides an intelligent induction method for lane level of highway reconstruction and expansion engineering, which specifically comprises the following steps:
and S1, determining the scope and type of the highway reconstruction and extension. Wherein, the scope of highway rebuilding and expansion includes: interrupting traffic and not interrupting traffic;
the expressway reconstruction and expansion range is set as the reconstruction and expansion range by dividing the corresponding area of the expressway, so that the expressway reconstruction and expansion range is conveniently regionally transmitted to a positioning navigation system, and a driving vehicle with GPS navigation conveniently starts to safely and quickly drive on an appointed line according to voice prompt.
The type of highway reconstruction and expansion is divided into two modes of traffic interruption and traffic non-interruption according to whether the original highway continues traffic operation, wherein the reconstruction and expansion under the condition of traffic non-interruption is already a main implementation mode of highway reconstruction and expansion.
And (3) traffic interruption: under the condition, the original road is fully closed, so that the shunted social vehicles can generate huge pressure on an adjacent road network, the development of local economy is not facilitated, time is wasted to a certain extent, the transportation cost is increased, and even the pressure and the influence from all aspects of society can be borne.
The traffic is not interrupted: the method has the advantages that the influence on local economy due to road reconstruction can be reduced, traffic requirements can be better met, and a better road service level can be provided. Therefore, most highways choose to be rebuilt without interrupting the traffic.
S2, shunting the vehicles according to the reconstruction and extension type of the expressway;
for the interrupted traffic, because the original road is totally closed, the invention adopts the traffic pavement diversion mode to divert the vehicles, transfers all the traffic flow on the construction road to the other road parallel to the construction road, generally the existing passage or provincial road, and sets the traffic sign at the diversion point. The traffic lane shunting is a special case of road network shunting, also called parallel lane shunting, and the traffic lane shunting mode has small influence on vehicle traveling, has short vehicle detouring distance, improves the road utilization rate and reduces traffic pressure.
For uninterrupted traffic, vehicles are shunted by adopting a construction road shunting or road network shunting mode. When the expressway is rebuilt, the construction area can build a construction access, and the construction access can be used for shunting the traffic flow. If the construction road section has available road networks, the construction access roads can be combined with the nearby road networks, so that the road utilization rate is improved, the cost of manpower, material resources and temporary cross installation of the one-time galvanized movable steel guardrail made of construction materials is reduced, and the method is green and environment-friendly. The road network shunting is to utilize the existing road network to disperse partial traffic flow or all traffic flow on the construction road to other roads before the construction area so as to reduce the construction interference of the road and ensure the construction progress and the construction safety.
S3, classifying the vehicle types according to the vehicle shunting mode;
travel vehicles can be classified into two types, namely trucks and buses according to service objects. Because the running speed of the truck is lower compared with that of a passenger car, the low-speed running can reduce the passing speed of the whole traffic flow, thereby causing resource waste and influencing construction; and the general tonnage of the truck is larger, the available space for the truck to pass through the construction road section is narrower, the truck is not beneficial to pass through, and the truck can generate larger vibration due to large mass when passing through the construction road section, so that the construction is not beneficial to constructors to carry out construction, therefore, the truck is taken as a shunting object.
And the distribution priority is also determined among the trucks, and the truck types of the trucks are determined through service level analysis by using a combined algorithm. According to the vehicle type classification standard, the trucks are classified into six types, namely small trucks, medium trucks, large trucks, super trucks, trailers and containers according to the load size. The larger the load is, the larger the damage degree to the road is, the poorer the traffic capacity to special environment is, and the larger the influence on construction is. And once traffic accidents occur at a construction road section, trucks with larger loads are more difficult to process, and more manpower and material resources are occupied. And (5) financial resources. Therefore, the invention takes large-sized and above trucks (including large trucks, extra large trucks, containers and trailers) as a first selective diversion truck type, a medium-sized truck as a second selective diversion truck type and a small truck as a third selective diversion truck type. All vehicles of the first selected shunting vehicle type are dispersed to other roads according to a first priority; all vehicles of the second selected shunting vehicle type are dispersed to other roads according to a second priority; and dispersing part or all vehicles of the third selected shunting vehicle type to other roads according to a third priority.
And the passenger car has little influence on road construction, and does not need to classify the car types.
S4, transmitting the range information of the reconstruction and expansion of the expressway, the vehicle diversion information and the vehicle type classification information to a positioning navigation device;
the received range information, vehicle shunting information and vehicle type classification information of the highway reconstruction and expansion are transmitted to a GPS navigation system of the highway section, and the highway section area reconstructed and expanded and the corresponding highway section area can be observed through map software or vehicle navigation software, so that a user can prepare in advance, and traffic jam is avoided in advance.
S5, for a high-speed running vehicle with a GPS positioning system, checking the condition of a front road section by using a positioning navigation device, and selecting an optimal road section according to the vehicle type;
for a high-speed running vehicle starting a GPS (global positioning system), received information is transmitted to a positioning navigation device, the information is uploaded to a server of the positioning navigation device through a service base station of an expressway, the road sections and states of a reconstruction and extension range can be displayed and checked on the positioning navigation device, and the optimal road section is selected according to the vehicle type of the positioning navigation device. And the corresponding voice prompt sentences and the sentences guiding the driving direction are uploaded by the server of the positioning navigation device, so that the driver can drive conveniently according to the voice prompt.
Through positioning navigation system's voice prompt, the convenience is gone to the driving vehicle who opens GPS positioning system carries out the voice guide, the mode of reminding through the pronunciation makes things convenient for the driver to change the way in advance, keep going on the line of going safely, the effectual back lane change of avoiding being close influences the normal current of vehicle, accelerate the current speed and the smoothness of highway reconstruction extension highway section, and the driving vehicle that does not open GPS positioning system directly carries out the lane change in advance according to the suggestion through the direction guiding device who sets up in advance, three group's direction guiding device's installation distance provides the distance and the time of lane change for the driving vehicle, the traffic accident that the effectual urgent lane change of avoiding arouses with add stifled.
And S6, for the high-speed running vehicle without starting the GPS, guiding the device in the front-stage construction direction of the reconstruction and extension according to the range of the reconstruction and extension of the expressway.
The direction guiding device is laid along the range of the protection fence surrounding the reconstruction and extension of the expressway, and the protection fence at the front section of the reconstruction and extension is obliquely placed, so that the vehicles can be conveniently guided to change lanes.
The protective fence and the direction guiding device play a protective role in a reconstruction and extension area of the highway together, and meanwhile, vehicles are guided to run on a correct row line, so that the passing safety of the vehicles is guaranteed, the phenomenon of congestion is reduced, and a good dredging effect is achieved.
The distance between the first direction guiding device and the expressway reconstruction and extension is 3km, the distance between the second direction guiding device and the expressway reconstruction and extension is 2km, and the distance between the third direction guiding device and the expressway reconstruction and extension is 2.5 km.
A distance of 1km is reserved between the first direction guiding device and the second direction guiding device, so that a driver can conveniently provide enough space for decelerating and changing lanes after finding the first direction guiding device, and the situation that the distance between the direction guiding device and a highway reconstruction and expansion range is too short to slow down and change lanes is avoided;
meanwhile, the second direction guiding device and the third direction guiding device can effectively avoid that a driver can timely reduce the speed of the vehicle and adjust the row line of the vehicle when not timely noticing the warning state and lane change reminding of the first direction guiding device, the lane change and reminding range of the vehicle is increased, safe and reliable lane change reminding is provided for a vehicle driver without a GPS, and therefore driving safety is guaranteed.
The direction guiding device is used for driving a vehicle in a state that a GPS positioning system is not started for navigation, the direction guiding device is arranged at the front section of a road reconstruction and extension range before construction, and a driver needs to change a road in advance through a road sign and a corresponding prompting frame to prevent congestion and unnecessary traffic accidents caused by deceleration after the vehicle reaches the vicinity of the reconstruction and extension range; the direction guiding device is arranged at the front section of the expressway reconstruction and extension area, and provides a function of reminding lane change in advance for running vehicles approaching the expressway reconstruction and extension area gradually, so that the passing of the vehicles is accelerated, and traffic accidents caused by the fact that the vehicles run too late for deceleration due to the fact that the lanes are not changed in time are avoided.
When the system is used, the voice guidance driving is conveniently carried out on the driving vehicle with the GPS through the voice prompt of the positioning navigation system, the driver can conveniently change lanes in advance according to the vehicle type of the driver through the voice prompt mode, the driving is kept on the safe driving line, the influence on the normal passing of the vehicle caused by the lane change after approaching is effectively avoided, the passing speed and the smoothness of the highway reconstruction and extension road section are accelerated, the driving vehicle without the GPS is directly subjected to the lane change in advance according to the prompt through the direction guide devices arranged in advance, the installation distances of the three groups of direction guide devices provide the lane change distance and the lane change time for the driving vehicle, and the traffic accidents and the blockage caused by the emergency lane change are effectively avoided.
