It is composed of The receiving unit 21 as the receiving unit corresponds to the information return terminal 2, and the transmitting unit 25 as the transmitting unit corresponds to the information transmitting terminal 1.

In FIG. 2, the solid line indicates the flow of information from the center 4 to the on-vehicle device 11 via the IC nail 3 when new registration or change of position information, linear information, town information, and the like is performed. That is, information input from the input unit 41 of the center 4 is transmitted from the transmission unit 43 to the IC nail 3 via the control unit 42. The information received by the receiving unit 31 of the IC nail 3 is stored in the storage unit 32,
The in-vehicle device 1 is controlled by the control unit 33 and wirelessly transmitted from the transmission unit 34.

4 to the center 4. The information received by the receiving unit 44 of the center 4 is stored in the storage unit 45, controlled by the control unit 42, and displayed on the display unit 46 as needed.

Next, a method of calculating the mixture ratio of the IC nail compatible vehicle and the ordinary vehicle in such a configuration will be described with reference to FIG. The vehicle 10 is an IC nail compatible vehicle, and has the in-vehicle device 11 including the information transmitting terminal 1 and the information receiving terminal 2 as described above.

The IC nail 3 has an IC 6 connected to the information control center 4 via a communication line c, and a sensor 5 connected to the IC 6. The IC 6 includes the above-described reception unit 31, storage unit 32, control unit 33, and transmission unit 34.

The sensor 5 checks the numerical values of all vehicles passing over the IC nail 3, including both ordinary vehicles and IC nail compatible vehicles. Regarding the IC nail compatible vehicle 10, there is a response request from the information transmitting terminal 1 to the IC 6 of the IC nail 3, and the IC 6 accurately measures the number of IC nail compatible vehicles 10 out of all the vehicles passed by the number of response requests. can do.

Through such a process, the local numerical information (the total number of vehicles and the number of vehicles compatible with IC nails) measured by each IC nail 3 installed on the road is transmitted from the IC 6 of the IC nail 3 to the communication line c. To the server 7 provided in the information center 4 via This numerical information is sent from all the IC nails 3 installed on the road to the server 7.

In the server 7, along with the database 8, line (each road) information is predicted from point (each IC nail 3) information, as described later, and the overall traffic flow situation is determined. As a result, a detailed traffic congestion state can be grasped by a method generally used at each point.

Further, the server 7 calculates the mixing ratio (rate) of the IC nail compatible vehicle 10 and the general vehicle for each IC nail 3 based on the total number of vehicles by the sensor 5 of the IC nail 3 and the number of IC nail compatible vehicles. Can be calculated. By clarifying the mixture ratio, it is possible to predict the travel time in real time, which is a great advantage for an IC nail compatible vehicle.

Next, a method of predicting line (each road) information from point (each IC nail 3) information and judging the overall traffic flow situation will be described with reference to FIG. FIG. 4 (a)
Is the minimum necessary information obtained from points (each IC nail 3) for predicting line (each road) information, and can be displayed on a display unit (not shown) of the server 7.

The number of passing vehicles in the information 9 is the total number of vehicles detected by the sensor 5 of each IC nail 3. The calculation of the mixture ratio is as described above, and the speed information is transmitted from the vehicle-mounted device 11. Information has been added.

The information 9 including the speed information, the number of vehicles, and the like obtained at the individual locations are all sent to the server 7 in the information control center 4 with regularity. In the server 7, the point information is converted into line information as shown in FIG. 4B and line information as shown in FIG. The example of the line information shown in FIG. 4B shows the average speed (km / h) of the passing vehicle at each point between Nagoya and Tokyo on the Tomei Expressway. FIG. 4 (c)
The example of the line information shown in (1) shows the number of vehicles passing per unit time (vehicles / hour h) at each point between Nagoya and Tokyo on the Tomei Expressway.

According to the line information as shown in FIGS. 4B and 4C, if the average speed is low and the number of passing vehicles is small at a certain point as seen at the point 80 km, for example, It can be predicted that congestion is occurring for some reason. The type of the cause is that the vehicle speed drops rapidly from the detailed past statistical data (point information as shown in FIG. 4A) obtained from each IC nail 3, and the speed decreases immediately after passing a certain point. Accurate discrimination can be performed, such as an accident traffic jam when it goes up, or a natural traffic jam when it occurs in a specific place or time zone.

Further, according to the line information as shown in FIGS. 4B and 4C, for example, as seen at a point of 60 km,
If the average speed is low at a certain point and the number of vehicles passing is large, it is predicted that a sudden brake must be applied several meters before that point, causing an accident such as a tunnel or a curve with poor visibility. Is judged to be at high risk.

The detailed traffic flow conditions obtained by these methods will be described later in detail.
It is used to determine the appropriateness of tolls on toll roads and to notify travelers. The mixture rate of IC nail-compatible vehicles 10 is effective in road management and the like when self-driving vehicles and the like spread in the future.

Finally, "variable toll roads" and "flexible signals (including signs)" will be described as applications that process information obtained by the IC nail 3 and feed back the information to travelers.

FIG. 5 shows the configuration of an IC nail information control system on a variable toll road. The IC nail compatible vehicle 10 is equipped with an on-vehicle device 11 including an information transmitting terminal 1 and an information receiving terminal 2. On the variable toll road, IC nails 3a, 3b, 3c, 3d are installed, and a tollgate 12 is provided. The configuration of the on-vehicle device 11 is as described in FIG. IC nails 3a, 3
The b, 3c, 3d and the tollgate 12 are connected to the server 7 and the database 8 of the information control center 4 via the communication line c.

The control unit 24 of the on-vehicle device 11 mounted on the IC nail-compatible vehicle 10 that has entered the variable toll road section uses the timer 23 to enter the IC nail 3d,
The information such as the vehicle number is transmitted from the transmitting unit 25 from the second information. The control unit 24 continues to transmit information such as the passing time and the vehicle speed to each of the IC nails (3c to 3a) even during traveling. The information is sent to the server 7 of the information control center 4 via the IC nails (3d to 3a) and the communication line c, and is stored and processed in the database 8.

When the IC nail compatible vehicle 10 pays a fee at the toll booth 12, the toll booth 12 communicates with the server 7 of the information control center 4 and occupies the road occupation time zone, average speed, etc. of the IC nail compatible vehicle 10. To determine the most appropriate rate.

FIG. 6 shows an example of calculating tolls on a variable toll road. In this embodiment, FIG. 6B shows the information (for example, the number of vehicles and the average traveling speed calculated as shown in FIG. 4) obtained from the IC nail 3 installed in the variable toll road section. Such a deviation is provided, and the fee is calculated based on the deviation. The deviation (1) determines the traffic congestion status at the entry time, and the deviation (2) determines the increase or decrease of the toll at the average speed. In the tollgate 12, the standard fare is set at a standard time zone (time zone of 1.0 in the deviation (1)) and a standard speed (speed of 1.0 in the deviation (2)) of 600 yen. Is set.

In FIG. 6A, assuming that the arrival time is 10:30, the distance is 80 km, the average speed is 80 km / h, and the toll gate time is 11:30, the vehicle travels in the standard time zone and the average speed is also the standard speed. Therefore, the deviation (1) is “1.0”,
The deviation (2) is also “1.0”. The method of calculating the appropriate fee is as follows.

Appropriate charge = standard charge x average speed / standard speed x deviation (1) x deviation (2) In this case, the appropriate charge is 600 yen x 80 (km / h) /
80 (km / h) × 1.0 × 1.0 = 600 yen.

In FIG. 6B, it is assumed that the entry time is 13:30, the off-peak hours, the average speed is 53.3 km / h (with congestion), and the toll gate time is 15:30. Since it is a quiet time zone, the deviation (1) is set to “0.7” and the average hourly speed is 53.
Since it is 3 km / h, the deviation (2) is set to “1.0”.

The appropriate fee in this case is 600 yen × 53.
3 (km / h) / 80 (km / h) × 0.7 × 1.0 =
It will be 280 yen. This not only guarantees compensation for the stress of travelers in traffic jams, but also leads to prevention of accidents due to overspeed, as overspeed leads to overpriced fares. By increasing the frequency of arranging the IC nails 3, it is possible to grasp the time during which the IC nail-compatible vehicle 10 is out of the road (such as a service area).

FIG. 7 shows a flexible signal (including a label).
1 shows a configuration of an IC nail information control system in FIG. The IC nail compatible vehicle 10 is equipped with an on-vehicle device 11 including an information transmitting terminal 1 and an information receiving terminal 2. On ordinary roads, IC nails 3a, 3b, 3
c, 3d are provided, and a signal (traffic light) / marker 13 is provided.

Each IC nail (3a-3) on a general road
d) is connected online to the server 7 in the information control center 4 via the communication line c, and furthermore, the signals (traffic signals) and the signs 13 are also connected to the server 7 online via the communication line c. It is connected.

As described above, the traffic flow can be grasped in detail by the IC nails (3a to 3d). The current uniform signal or sign representation does not reflect real-time traffic flow and sometimes disturbs good traffic flow.

In this IC nail information control system, the traffic signal / sign 13 is controlled by using the IC nail 3 which can grasp the real-time traffic flow accurately and in detail, and always maintain a good traffic flow.

For example, it is assumed that it is possible to confirm from the information of the IC nail 3 that the traffic in the north-south direction is small and the traffic in the east-west direction is causing a natural traffic jam at a certain intersection. In this case, the traffic light 1 of this intersection connected online
3 extends the blue time in the east-west direction, and the sign 13 provides detour information and the like to the vehicle turning right and left from the north-south direction to the east-west direction. Further, the number of right turn desired vehicles is accurately determined, and the right turn signal display time is changed.

Next, detection of an IC nail compatible vehicle 10 equipped with the on-vehicle device 11 and a general vehicle will be described. Vehicles running on the road include both IC nail compatible vehicles 10 and ordinary vehicles. If traffic control is performed in such a traffic environment, it is necessary to identify whether each vehicle is an IC nail-compatible vehicle 10 or a general vehicle together with the arrangement of individual vehicles on the road. Generally, the IC nail compatible vehicle 10 usually has a communication means between the IC nail compatible vehicle 10 and the infrastructure side, that is, a road-to-vehicle communication function. Identifying the car 10 is easy.

In the above-described IC nail information control system, if the vehicle is an IC nail compatible vehicle 10, road-to-vehicle communication with the IC nail 3 is used, and whether the vehicle is an IC nail compatible vehicle 10 can be easily determined based on the response. You can judge whether it is a general car. The first call may be from the IC nail compatible vehicle 10 or from the IC nail 3.

However, if general vehicles are mixed, there is no communication function, so that even the presence of vehicles cannot be easily detected. Therefore, as shown in FIG. 8, an array of CCD cameras 50 as imaging means is laid so as to cover the entire road, and the center 4 first grasps the positions of all vehicles by image processing, and furthermore, the IC nail described above. Each vehicle can be specified by superimposing the result of communication with the corresponding vehicle 10. IC nail 3
Is fixed on the road, the communication position with the IC nail-compatible vehicle 10 can be specified if the individual IC nails 3 have positional information.

As shown in FIG. 9, the position information to be provided to the IC nail 3 includes a distinction such as an expressway, a national road, and a local road, a road number thereof, a serial number of the IC nail 3 from the starting point, and the like. . As another method, latitude and longitude may be used.

As shown in FIG. 10, specifying the position of an individual vehicle by image processing requires the use of a product that detects the occurrence of an accident based on the presence or absence of an image shift at a certain time difference. It is possible to specify the position of each vehicle by image processing as an extension of. In FIG. 10, the position of the vehicle is specified by the image shift between the image B in the current image stored in the memory (not shown) obtained by the CCD camera 50 and the image A in the image at a time immediately before.

As another method for specifying the position of each vehicle, it is possible to specify the position using a laser beam instead of a CCD camera. As described above, according to the embodiment of the present invention, the control information can be bidirectionally communicated by making the IC nail into a network, and can be used as profit for the manager and the traveler.

Other information contents transmitted to travelers from IC nails include current location information, road alignment information, vehicle-to-vehicle communication, town information, golf and ski resort information, communication karaoke, and Internet information. No.

Further, by laying the IC nails on the road, even if the intervals between the installation and the installation are narrow, there is no problem in terms of aesthetics. Fixed information is given to the IC nail,
In addition, since it has an arithmetic function, a function not available in the past can be realized. An unprecedented service can be realized by the network function of the IC nail.
