Detailed Description

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

Fig. 1 is a diagram illustrating a scene in which a traveling vehicle approaches a crosswalk 301 where no traffic signal is installed. A child 303 carrying the bag 302 stands on the left side of the road as viewed from the driver's seat. The child 303 is an example of a traverser.

In japan, it is prescribed that pedestrians in the crosswalk 301 take priority, and when there is a pedestrian or the like that intends to cross the crosswalk 301, a vehicle approaching the crosswalk 301 must be temporarily stopped immediately before reaching the crosswalk 301, and not obstruct the passage of the pedestrian or the like. However, the driver is not consciously aware of the active temporary stop or the intention of a pedestrian or the like to cross is not transmitted to the driver, and therefore the suspension rate of the vehicle in the crosswalk 301 where no traffic signal is provided is considered to be low.

In the embodiment, therefore, in order to increase the temporal parking rate of the vehicle,

1. the driver's awareness is increased to make it actively stop temporarily,

2. it is possible to easily convey the intention of a pedestrian or the like crossing to the driver and assist a crossing person who crosses the crosswalk 301 where no traffic signal is provided.

In an embodiment, the crosser should present the identifier 304 to the vehicle side indicating the intent to make the traverse. That is, the child 303 of fig. 1 shows the identifier 304 to the vehicle side, indicating the intent of the traversal. A two-dimensional code (registered trademark) as an example of the identifier 304 is attached to the bag 302 carried by the child 303. The identifier 304 may be attached to a carrying item other than the bag 302, such as a hat, a bag, or clothing. However, it is preferable to affix or fix the identifier 304 to an approximately flat portion of the article that is visible from the vehicle side. Alternatively, the child 303 may carry a card bearing the identifier 304 and be displayed as it traverses. An example of such a crossing person support will be described in detail below.

Fig. 2 is a block diagram illustrating a main part configuration of a cross-person support system 500 including the on-board unit 10 as the advertisement playback device of the embodiment. In fig. 2, for example, the crossing person support system 500 is constituted by a CM (Commercial Message) information providing server 100 and a reward management server 200 which are possessed by a business entity that performs the crossing person support service, and an on-vehicle unit 10 which is installed in a vehicle, not shown, driven by a service user who has registered the business entity with the user.

The following describes an outline of advertisement playback performed by the on-board unit 10. When the identifier 304 is detected beside the crosswalk 301 in the traveling direction of the vehicle, the on-board unit 10 notifies the driver that there is a pedestrian crossing the intention. When the driver pauses the vehicle in front of the crosswalk 301, the in-vehicle unit 10 performs advertisement playback based on the CM information acquired from the identifier 304. The CM information is information for playing an advertisement in a shop or the like in an area where the vehicle travels.

An example of the advertiser is a business, a shop, or the like in a region where the pedestrian crossing 301 is installed. Advertising fees are paid from the advertiser to the business entity implementing the traversar assistance services business. The business entity implementing the cross-walk assistance service operates the business on an advertising fee basis and awards a prize to the driver of the vehicle temporarily parked near the crosswalk 301. The reward is given to the driver in the form of points, for example, and can serve as a partial price when the driver purchases a good or receives a service in an advertiser's store or the like.

In addition, the business entity implementing the traverser assistance service provides the advertiser with a sticker, badge, card, or the like, to which is attached an identifier 304 that establishes an association with the CM information. The advertiser uses a sticker, badge or card, etc. with the identifier 304 attached as a promotional item. The crossreader affixes a sticker or the like with the identifier 304 attached thereto to the carrying article, or carries a card or the like with the identifier 304 attached thereto.

In fig. 2, the CM information providing server 100, the bonus management server 200, and the in-vehicle unit 10 are connected to a communication network 30 such as a wireless communication network, the internet, a telephone network, and the like. In fig. 2, one on-board unit 10 is shown for convenience, but the on-board units 10 should be provided on a plurality of vehicles, respectively. Note that, although one CM information providing server 100 is shown in fig. 2, the functions of the CM information providing server 100 may be distributed among a plurality of server devices. Similarly, although one bonus management server 200 is shown in FIG. 2, the functions of the bonus management server 200 may be distributed among a plurality of server devices.

< advertisement playing device (vehicle unit)

Fig. 3 is a block diagram illustrating a main portion structure of the on-board unit 10 of fig. 2. The in-vehicle unit 10 has a processing unit 1, an input unit 2, a camera 3, a sensor group 4, a storage unit 5, a communication unit 6, a microphone 7, a speaker 8, and a display 9.

The processing unit 1 is constituted by a microcomputer and its peripheral circuits. The processing unit 1 executes predetermined processing based on a signal input from the input unit 2, image information acquired by the camera 3, information acquired by the sensor group 4, data stored in the storage unit 5, and the like, and a signal received from the outside of the in-vehicle unit 10 via the communication unit 6, and the like, and outputs a control signal for each unit inside the in-vehicle unit 10.

The processing unit 1 includes an image recognition unit 11, a determination unit 12, a notification unit 13, a crossing time estimation unit 14, a CM information acquisition unit 15, and a playback unit 16.

The image recognition unit 11 performs recognition processing of the crosswalk 301 and the identifier 304 based on the image information in front of the vehicle acquired by the camera 3. The crosswalk 301 is identified based on road markings indicating the presence of the crosswalk 301 or road markings marked on the road. The crosswalk 301 may also be identified from image information in front of the vehicle.

The determination unit 12 determines whether or not both the crosswalk 301 and the identifier 304 are recognized. When both the pedestrian crossing 301 and the identifier 304 are recognized as in the case illustrated in fig. 1, the notification unit 13 notifies the driver of the presence of a pedestrian having crossing intention. For example, a message "there is a crosswalk" is generated, and a voice message is played through the speaker 8 described later. Alternatively, the message may be displayed on the display 9 described later.

The crossing time estimating unit 14 estimates a crossing time until the crossing person has crossed the crosswalk 301, based on the image information in front of the vehicle acquired by the camera 3. For example, the crossing time is inferred from the road width inferred based on the image information and the age group of the crossing person inferred based on the image information. The estimation is performed based on the average walking speeds of the age groups such that the estimated crossing time estimated for a young person whose age group is 10 to 29 years old is 5 seconds, and the estimated crossing time estimated for an old person whose age group is 70 years old or older is 10 seconds.

When the vehicle temporarily stops in front of the crosswalk 301, the CM information acquisition unit 15 acquires CM information for advertisement broadcasting. When the vehicle is temporarily stopped in front of the crosswalk 301, the camera 3 can capture the identifier 304 in a larger size than when the vehicle is approaching the crosswalk 301. The CM information acquiring unit 15 reads out the detailed information of the identifier 304 from the image information acquired by the camera 3. If necessary, the area corresponding to the identifier 304 in the image information acquired by the camera 3 may be subjected to an electronic zoom (also referred to as a digital zoom) process or the like, so that the detailed information of the identifier 304 can be easily read out.

For example, when the identifier 304 recognized by the image recognition unit 11 is a two-dimensional code, the CM information acquisition unit 15 can acquire the CM information by either one of the following two.

1. When the CM information itself is encoded and recorded in the two-dimensional code, the CM information is acquired by decoding the read code.

2. When URL (Uniform Resource Locator) information is encoded and recorded in the two-dimensional code, CM information is acquired from a server (CM information providing server 100 in the embodiment) corresponding to the URL obtained by decoding the read code via a communication unit 6 described later.

In addition, for example, in the case where the identifier 304 recognized by the image recognition portion 11 is constituted by a figure or a logo (e.g., trademark) associated with the advertiser, the CM information acquisition portion 15 can acquire the CM information as follows. In this case, the graphics or logo is associated with the referenced URL in advance. When a graphic or logo is attached as the identifier 304, the CM information acquisition unit 15 acquires CM information from a server (the CM information providing server 100 in the embodiment) corresponding to a URL with which the graphic or logo is associated via the communication section 6 described later.

The CM information acquiring unit 15 is configured to acquire CM information whose playback time falls within the estimated crossing time of the crossing person estimated by the crossing time estimating unit 14. For example, in the case where the CM information itself is encoded and recorded in a two-dimensional code, the CM information falling within the inferred traversal time is acquired from the two-dimensional code. When the URL information is encoded and recorded in the two-dimensional code, information indicating the estimated crossing time is transmitted to the server corresponding to the URL via the communication unit 6 described later, and the CM information within the estimated crossing time is acquired from the server.

When the temporary stop of the vehicle is detected by the output signal of the sensor group 4 described later, the playback unit 16 plays back the CM information acquired by the CM information acquisition unit 15. When the CM information includes image information, the playback section 16 can display the image information on the display 9 described later. When the CM information includes voice information, the playback unit 16 can play back the voice information through the speaker 8 described later.

When the playback unit 16 plays the CM information to the end, the processing unit 1 stores information indicating the end of playback (for example, a CM playback flag) in the storage unit 5, which will be described later, together with date and time information. When the output signal of the sensor group 4 described later detects that the vehicle starts to move while the CM information is being played (from the start of the playing to the end of the playing), the processing unit 1 interrupts the playing of the CM information, and stores information indicating that the playing has been interrupted (for example, a CM playing interruption flag) in the storage unit 5 described later together with date and time information.

For example, when it is detected that the vehicle has arrived at the destination and stopped based on the output signal of the sensor group 4 described later, the playback unit 16 restarts the playback of the CM information for which the playback has been interrupted. Note that the restart of the playback may be started from the point of time when the playback of the CM information is interrupted, or may be started from the beginning of the CM information. In addition, when the vehicle start is detected during the CM information playback, the CM information playback may be switched to the voice-only playback and may be ended. At this time, it is also possible to decide which of the stop playback CM information and the playback-only voice is to be switched to according to the playback remaining time. For example, the playback may be switched to only playback when the playback remaining time is less than a predetermined length, and switched to stop playback when the playback is longer than or equal to the predetermined length.

When the CM information whose playback has been restarted by the playback unit 16 is played back to the end, the processing unit 1 stores the CM playback completion flag in the storage unit 5 described later, and deletes the corresponding CM playback interruption flag from the storage unit 5.

The input unit 2 includes various switches operated by the driver, for example. Note that a touch panel provided on the display screen of the display 9 may be configured as the input unit 2. The input unit 2 transmits signals input by operations of various switches and the like to the processing unit 1.

The camera 3 is constituted by a camera for ADAS (Advanced driver assistance systems, Advanced driver assistance system), for example. The camera 3 transmits image information in which the front of the vehicle is photographed to the processing unit 1.

The sensor group 4 has: a detector that detects an operation state of a driving operation member (operation member) that changes a motion of the vehicle according to the operation amount; and a detector that detects a motion of the vehicle. The steering sensor 41 detects the rotation direction, rotation angle, rotation speed, and the like of the steering wheel. The acceleration sensor 42 detects a depression amount, a depression force, and the like of an accelerator pedal. The brake sensor 43 detects the amount of depression of the brake pedal, the force of depression, and the like.

In addition, the vehicle speed sensor 44 detects the traveling speed of the vehicle. The acceleration sensor 45 detects the above-described pitch, yaw, and roll by detecting accelerations in the three axial directions, respectively. The parking brake sensor 46 detects the activation/deactivation of the parking brake.

The storage unit 5 includes a volatile or nonvolatile memory not shown. The storage unit 5 stores various programs and various data executed by the processing unit 1. The storage unit 5 stores the CM play completion flag 51 and the CM play interruption flag 52. The storage unit 5 also stores the CM information 53 acquired by the CM information acquisition unit 15 and a driver id (identification)54 of a driver who drives the vehicle. The driver ID is registered in the processing unit 1, for example, when the driver gets into the car.

For example, when the vehicle arrives at the destination and the driver leaves the vehicle, the information of the CM playback completion flag 51 stored in the storage unit 5 is transmitted to the bonus management server 200 through the communication unit 6, which will be described later, together with the date and time information and the driver ID 54. When the information of the CM play completion flag 51 is transmitted to the bonus management server 200, the CM play completion flag 51 in the storage section 5 is deleted by the processing section 1.

The communication unit 6 is configured to be able to communicate with the CM information providing server 100 and the bonus management server 200 through a wireless public line such as a telephone network, an internet line, or the like, and the communication network 30. The communication of the communication unit 6 is controlled by the processing unit 1.

The microphone 7 acquires an instruction issued by the driver. The audio signal picked up by the microphone 7 is input to the processing section 1 as audio data via an a/D converter, for example.

The speaker 8 plays the voice message generated by the processing unit 1.

The display 9 displays information based on the signal output from the processing section 1.

The arithmetic unit 130 includes a CM information acquisition unit 131, a CM information selection unit 132, and an output unit 133.

When the transmission CM information is requested from the in-vehicle unit 10, the CM information acquiring unit 131 acquires the CM information from the database corresponding to the URL specified from the in-vehicle unit 10 among the CM information databases 141A, 141B, and 141C.

When the transmission of the CM information is requested from the in-vehicle unit 10, the CM information selecting unit 132 selects the CM information that falls within the estimated required time transmitted from the in-vehicle unit 10 among the CM information acquired by the CM information acquiring unit 131.

The output unit 133 transmits the CM information selected by the CM information selection unit 132 to the in-vehicle unit 10 via the communication unit 110.

The storage unit 140 includes a volatile or nonvolatile memory not shown. The storage unit 140 stores various programs and various data executed by the arithmetic unit 130. The storage unit 140 has a functional configuration in which the CM information databases 141A, 141B, and 141C are assigned as memories.

The CM information database 141A stores first CM information 142A, second CM information 143A, and third CM information 144A about the first advertiser. The first CM information 142A, the second CM information 143A, and the third CM information 144A differ at least in their respective play times. Each CM information is, for example, any of data of a moving image (including an image to which voice information is added), a still image (including an image on which text information is superimposed and an image to which voice information is added), a message image (an image including text information in a screen without background), a voice message, and the like. First to third CM information 142A to 144A about the first advertiser are prepared in advance according to the length of the play time and stored in the CM information database 141A.

The first CM information 142B, the second CM information 143B, and the third CM information 144B regarding the second advertiser and the first CM information 142C, the second CM information 143C, and the third CM information 144C regarding the third advertiser are also the same.

< description of the flow chart >

The flow of processing for acquiring CM information from the identifier 304 and playing the information will be described with reference to fig. 6, in which the in-vehicle unit 10 is an advertisement playing device.

Fig. 6 is a flowchart illustrating a processing flow of a program executed by the processing section 1 of the on-board unit 10. For example, when the parking brake is released after the engine on/off button or the system on/off button of the vehicle is turned on, the processing unit 1 repeatedly executes the processing of fig. 6.

In step S100, the processing unit 1 starts acquiring the vehicle periphery information, and proceeds to step S110. Specifically, the image recognition unit 11 performs the recognition processing of the crosswalk 301 and the identifier 304 based on the image information of the traveling direction of the vehicle acquired by the camera 3.

In step S110, the processing unit 1 determines the presence or absence of the crosswalk 301 by the determination unit 12. When the image recognition unit 11 recognizes the crosswalk 301, the determination unit 12 determines step S110 as positive (yes in S110), and proceeds to step S110, and when the image recognition unit 11 does not recognize the crosswalk 301, the determination unit 12 determines step S110 as negative (no in S110), and repeats the determination process.

In step S120, the processing unit 1 determines the presence or absence of a pedestrian by the determination unit 12. When the image recognition unit 11 recognizes a pedestrian, the determination unit 12 determines the determination result at step S120 to be positive (yes at S120), and proceeds to step S130, and when the image recognition unit 11 does not recognize a pedestrian, the determination unit 12 determines the determination result at step S120 to be negative (no at S120), and returns to step S110, and the above determination process is repeated.

In step S130, the processing unit 1 determines whether or not the pedestrian has the crossing intention by the determination unit 12. When the identifier 304 is recognized by the image recognition unit 11, the determination unit 12 determines that step S130 is affirmative (yes in S130), and the process proceeds to step S140, and when the identifier 304 is not recognized, the determination unit 12 determines that step S130 is negative (no in S130), and the process returns to step S110, and the determination process is repeated. In step S130, it is not necessary to read the detailed information of the identifier 304, and it is sufficient if the presence or absence of the identifier 304 can be determined.

In step S140, the processing unit 1 notifies the driver of the presence of a pedestrian having a crossing intention by the notification unit 13, and the process proceeds to step S150.

In step S150, the processing unit 1 determines whether or not the vehicle is stopped. When the temporary stop of the vehicle is detected from the output signals of the sensor group 4, the processing unit 1 makes the determination of step S150 affirmative (yes in S150) and proceeds to step S160, and when the temporary stop of the vehicle is not detected, the processing unit 1 makes the determination of step S150 negative (no in S150) and returns to step S110, and repeats the above determination processing.

In step S160, the processing unit 1 determines whether or not CM information can be acquired. When the CM information acquisition unit 15 reads the detailed information of the identifier 304, the processing unit 1 determines the determination of step S160 to be affirmative (yes in S160), and proceeds to step S170, and when the detailed information of the identifier 304 is not read, the processing unit 1 determines the determination of step S160 to be negative (no in S160), and proceeds to step S260.

In step S170, the processing unit 1 estimates the crossing time until the crossing person has crossed the crosswalk 301 by the crossing time estimation unit 14, and proceeds to step S180.

In step S180, the processing unit 1 determines whether or not CM information that can be played within the estimated traversal time is acquired. When the CM information acquisition unit 15 acquires the CM information whose playback time falls within the estimated traversal time, the processing unit 1 determines the step S180 as affirmative (yes in S180), and proceeds to step S190, and when the CM information acquisition unit 15 does not acquire the CM information whose playback time falls within the estimated traversal time, the processing unit 1 determines the step S180 as negative (no in S180), and proceeds to step S240.

In step S190, the processing unit 1 causes the playback unit 16 to start playing back the CM information acquired by the CM information acquisition unit 15, and the process proceeds to step S200. In step S200, the processing unit 1 determines whether or not the vehicle is stopped. When the temporary stop of the vehicle is continuously detected based on the output signals of the sensor group 4, the processing unit 1 makes an affirmative decision in step S200 (yes in S200), and proceeds to step S210. When detecting that the temporary stop of the vehicle has not been continued based on the output signal of the sensor group 4, the processing unit 1 determines step S200 as negative (S200: no), and proceeds to step S240.

In step S210, the processing section 1 determines whether the playback of the CM information is completed. When the CM playback by the playback unit 16 is completed, the processing unit 1 determines that step S210 is affirmative (S210: yes), and proceeds to step S220. When the CM playback by the playback unit 16 is not completed, the processing unit 1 determines that step S210 is negative (S210: no), returns to step S200, and repeats the above-described processing.

In step S220, the processing unit 1 notifies the driver that the reward is received, and the process proceeds to step S230. The notification is, for example, generation of "thank you assisting the transvership service. The driver is given an integrated point. "this message, a voice message is played through the speaker 8. Alternatively, the message may be displayed on the display 9.

In step S230, the processing unit 1 stores the CM information play-to-last CM play completion flag 51 in the storage unit 5, and ends the processing of fig. 6.

In step S260, the processing unit 1 determines whether or not the vehicle has transmitted information, wherein step S260 is a step that is entered when the determination of step S160 is negative (S160: no). When the vehicle transmission information is detected from the output signals of the sensor group 4, the processing unit 1 determines step S260 as affirmative (yes in S260) and proceeds to step S270. When the vehicle transmission information is not detected, the processing unit 1 determines that step S260 is negative (no in S260), returns to step S160, and repeats the above-described processing.

In step S270, the processing unit 1 notifies that the CM information cannot be acquired, and ends the processing of fig. 6. The notification is, for example, to generate "CM information is unavailable. "this message, a voice message is played through the speaker 8. Alternatively, the message may be displayed on the display 9.

In step S240, the processing unit 1 notifies that the CM information is saved, and proceeds to step S250, where step S240 is a step that proceeds when the determination of step S180 or step S200 is negative. The notification is, for example, generation of "save until last CM information. "this message, a voice message is played through the speaker 8. Alternatively, the message may be displayed on the display 9.

In step S250, the processing unit 1 stores the CM-play-interruption flag indicating that the CM information play has been interrupted and the CM information that cannot be played to the end in the storage unit 5, and ends the processing of fig. 6. When it is determined in step S180 that the determination is negative (S180: no), the CM information (the CM information whose playback time exceeds the estimated crossing time) corresponding to the identifier 304 is acquired, and the CM information is stored in the storage unit 15 together with the CM playback interruption flag.

< procedure >

A program for executing the processing executed by the processing unit 1 of the in-vehicle unit 10 as the advertisement playback device, that is, the processing illustrated in fig. 6, may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be supplied to the in-vehicle unit 10. The computer-readable recording medium is a portable recording medium such as a flexible disk, a magneto-optical disk, an optical disk, or a memory card, or a storage device such as a hard disk incorporated in a computer system. The computer System includes an OS (Operating System) and hardware of peripheral devices, as in the illustrated in-vehicle unit 10.

The computer-readable recording medium may include a medium that dynamically holds a program for a short time, such as a communication line when the program is transmitted via a communication line of the communication network 30 such as the internet or a telephone line network, or a medium that holds a program for a certain period of time, such as a volatile memory in a computer system serving as a server or a client in this case. The program may be used to realize a part of the functions, or may be combined with a program already recorded in a computer system to realize the functions.

The in-vehicle unit 10 can receive a program recorded on a DVD (Digital Versatile Disc) or the like, for example. The in-vehicle unit 10 may receive the program via a communication line.

For example, the program is transmitted from a server computer that stores the program in a recording medium such as a hard disk to the in-vehicle unit 10 via a communication line of the communication network 30. That is, the program is transmitted as a data signal by a carrier wave and transmitted via a communication line. The in-vehicle unit 10 receives the transmitted program and stores the program in the storage unit 5.

As such, the program may be provided as a computer program product readable by a computer in various forms of a recording medium, a carrier wave, and the like.

According to the present embodiment, the following operational effects can be achieved.

(1) The in-vehicle unit 10 as an advertisement playback device is installed in a vehicle and plays back an advertisement based on advertisement information (CM information). The on-board unit 10 includes: an image recognition unit 11 that recognizes the identifier 304 from an image obtained by capturing an image of the traveling direction of the vehicle; a notification unit 13 that notifies a driver of the vehicle of the presence of a crossroad 303 when the identifier 304 is recognized by the image recognition unit 11; an information acquisition unit (CM information acquisition unit) 15 that acquires CM information from the recognized identifier 304; a playback unit 16 that plays back CM information when the vehicle is temporarily stopped before the crossing person 303; and a storage unit 5 for storing a CM reproduction completion flag 51 for giving a reward to the driver when the reproduction of the CM information is completed in the reproduction unit 16.

With this configuration, the driver can be prompted to stop the vehicle and assist the crosser 303 in crossing the road. The transverser 303 can indicate the intent of the traversal simply by presenting the identifier 304. Further, since the information necessary for giving a reward to the driver can be retained by storing the CM broadcast completion flag 51 in the storage unit 5, the driver can be more conscious of the temporary stop and the driver's enthusiasm for the temporary stop can be increased.

(2) In the in-vehicle unit 10, the CM information acquisition unit 15 acquires CM information in which the playback time corresponds to the crossing time of the crossing person 303 estimated from the width of the road, among the plurality of CM information based on the recognized identifier 304. More specifically, CM information is acquired in which the playback time of the plurality of CM information based on the recognized identifier 304 falls within the crossing time of the crossing person 303 estimated based on the width of the road.

With this configuration, it is possible to play CM information of an appropriate length in accordance with the traversal time of the traverser 303. Note that a plurality of CM information having different playback times may be acquired by the CM information acquisition unit 15, and the playback unit 16 may play back CM information selected from the plurality of CM information, based on the estimated crossing time of the crossing person 303 estimated based on the width of the road.

(3) In the in-vehicle unit 10, the CM information acquisition unit 15 reads the CM information included in the identifier 304, or acquires the CM information from the CM information providing server 100 outside the vehicle based on the URL information included in the identifier 304.

With this configuration, the CM information may not be stored in the in-vehicle unit 10 in advance.

(4) In the in-vehicle unit 10, when the vehicle starts at the end of the playback of the CM information, the playback unit 16 stops the playback or switches to only the playback of the voice.

With this configuration, it is possible to prevent the attention of the driver from being attracted to the advertisement display during the traveling of the vehicle.

(5) In the in-vehicle unit 10, the playback section 16 restarts the playback of the advertisement information when the vehicle stops, for example, when the vehicle arrives at the destination to stop after switching to the suspension of the playback. When the playback of the CM information restarted by the playback unit 16 is completed, the storage unit 5 stores information for giving a reward to the driver.

With this configuration, information necessary for giving a reward to the driver can be retained as much as possible, and the driver's motivation for temporary parking can be further increased.

(6) In the in-vehicle unit 10, the storage section 5 stores a CM play completion flag 51, and the CM play completion flag 51 is used to give a reward to the advertiser of the CM information.

With this configuration, the vehicle can be raised in the sense that the vehicle is temporarily stopped by the vehicle. In addition, unlike the prior art, since the award is provided by an advertisement fee, the transverser 303 can receive the assistance of traversing the road free of charge.

(7) The transverser assist system 500 assists a transverser 303 traversing a road, and includes: an in-vehicle unit 10; an advertisement information providing server 100 that provides CM information to the in-vehicle unit 10; and a reward management server 200 that manages rewards that are given to the driver ID54 of the driver driving the vehicle. The in-vehicle unit 10 requests the CM information from the advertisement information providing server 100 based on the URL information included in the identifier 304, the advertisement information providing server 100 provides the requested CM information to the in-vehicle unit 10, and when the award management server 200 receives the information of the CM play completion flag 51 indicating that the play of the CM information is completed from the in-vehicle unit 10, the award is given to the driver ID 54.

With this configuration, the driver can be prompted to stop the vehicle and assist the crosser 303 in crossing the road. In addition, since necessary CM information is provided to the in-vehicle unit 10 every time, the CM information may not be stored in advance. In addition, since the driver is rewarded, the driver's awareness of the temporary stop can be improved.

The above embodiment can be modified into various modes. Hereinafter, a modified example will be described.

(modification 1)

In the embodiment, the child 303 attached with the identifier 304 to the bag 302 has been described as an example of the crossing person. In addition, a hat with an identifier 304 attached may also be worn to indicate intent to traverse, such as shown in FIG. 7A. As shown in fig. 7B, a packet or the like to which an identifier 304 formed of a figure or the like related to the advertiser is attached may be carried to indicate the intention of traversal. In addition, as shown in fig. 7C, instead of the transverser indicating the intention of the transversing, an identifier 304 may be added to the transversing flag used in a so-called daemon.

(modification 2)

A driver terminal such as a smartphone owned by the driver may be caused to process part or all of the processing performed by the processing unit 1 of the in-vehicle unit 10. For example, in the embodiment, the driver terminal may be configured to perform the processes performed by the CM information acquisition unit 15 and the playback unit 16 of the processing unit 1. In modification 2, data and the like are transferred between the in-vehicle unit 10 and the driver terminal by performing short-range wireless communication between the communication unit 6 of the in-vehicle unit 10 and the communication unit of the driver terminal, for example. Further, communication is performed between the driver terminal and the CM information providing server 100 and between the driver terminal and the bonus management server 200 through the communication network 30, respectively.

(modification 3)

In the embodiment, an example in which a crosswalk traverses a road on which a crosswalk 301 is provided is described. If step S110 of the process illustrated in fig. 6 is omitted, it is possible to cope with a case where a crosswalk is present at a location where the crosswalk 301 is not provided and a person who intends to cross the road. However, if the preceding vehicle suddenly stops on a road on which the crosswalk 301 is not provided, the driver of the following vehicle may be annoyed, and therefore, the vehicle needs to stop temporarily after confirming the traveling state of the following vehicle or the like, and the driver needs to pay further attention to the situation around the own vehicle.

One or more of the above embodiments and modifications may be arbitrarily combined, or modifications may be combined with each other.

The invention can properly assist pedestrians to cross roads.
