Description

  The present invention relates to a vehicle guidance system, and more specifically to a vehicle guidance system that safely guides a vehicle used at an entrance / exit for an ETC vehicle installed at an entrance / exit of a toll road.

  In recent years, ETC systems (Electronic Toll Collection System) have been installed at toll gates on toll roads. As shown in FIG. 1, the ETC system automatically settles tolls using wireless communication between the roadside antennas 3 and 5 installed at the toll gate and the vehicle-mounted device 20 attached to the vehicle 14. It is a system that can pass through toll gates non-stop. The ETC system is basically installed on the dashboard of the vehicle 14 and the on-board device 20 that is a wireless device that communicates information necessary for fee calculation, and the fee payer's inserted and used therein. Consists of an IC card (ETC card) 21 on which contract information is recorded, and roadside antennas (ETC roadside radio devices) 3 and 5 that are installed on the lane of the toll booth and perform radio communication with the vehicle-mounted device 20 Has been. Among them, the on-vehicle device 20 is sold to the user by a private company, the ETC card 21 is lent to the user by the credit company, and the roadside antennas 3 and 5 are installed by the toll road operator.

  As shown in FIG. 2, in the entrance ticketing system used in many toll roads, the entrance information is wirelessly transmitted from the roadside antennas 3 and 5 to the vehicle-mounted device 20 at the entrance toll gate, and after traveling on the toll road 7, At the exit toll gate, the entrance information is wirelessly transmitted from the vehicle-mounted device 20 to the roadside antennas 3 and 5, the fee is calculated by a separately provided fee calculation computer, and the fee information is sent from the roadside antennas 3 and 5 to the vehicle-mounted device 20. Wireless transmission. In the simple collection system of a flat fee such as in an urban highway, it is sufficient that such an ETC is installed in at least one place between the entrance and the exit. The roadside antennas 3 and 5 may be one or more than two.

The benefits of ETC are wide-ranging, such as elimination of traffic jams at toll booths, noise reduction by stopping / departing at toll booths, environmental improvement by reducing exhaust gas, and convenience and management cost reduction due to cashless The effect is expected.

[ETC system vehicle guidance system for entrance toll gates]
FIG. 3 shows a vehicle guidance system using an ETC system used at an entrance toll gate.

  The vehicle travels from the general road 8 toward the toll road 7, and a toll gate 9 is provided therebetween. Conventionally, the toll gate 9 has been prepared with three lanes. Lanes (A → D) are dedicated to ETC, and lanes B and C are for ordinary vehicles. In the present embodiment, a lane E (also referred to as “re-entry lane”) that newly branches from A is prepared. Here, the route A → D is a route that goes to the toll road 7 through the ETC gate 5, and the route A → E is a lane for re-entering the toll gate 9.

  The lanes A → D are basically provided with roadside antennas 3 and 5 and perform wireless communication with the vehicle-mounted device. FIG. 4 shows details of lanes A → D and A → E, which will be further described. A vehicle enters from a general road 8, passes through a pre-opened breaker 1, is detected by a vehicle detection device 2 a, and is connected to a roadside antenna (antenna before gate) 3 that determines whether wireless communication is possible. Passed and detected by the vehicle detection device 2b.

  When it is determined that wireless communication is possible with the antenna 3 before the gate, the guide device 4-1 opens with the guide device 4-2 closed, passes through the vehicle detection device 2c, and passes through the road antenna (ETC gate). The vehicle can travel to the toll road 7 by receiving the entrance information for the vehicle-mounted device from 5.

  When it is determined that wireless communication with the antenna 3 before the gate is impossible or impossible, the guide device 4-1 is closed while the guide device 4-1 is closed, and the vehicle proceeds to the lane E to move the vehicle detection device 2d side. As a result, the vehicle returns to the point where one of the lanes A, B, and C is selected. Conventionally, since the re-entry lane E did not exist, it was necessary to stop the vehicle and call an attendant with an intercom or the like when the opening / closing bar 4-1 could not move forward. As a result, congestion at the toll booth 9 is promoted, and the original purpose of the ETC cannot be achieved. In addition, if the vehicle with the open / close bar 4-1 descending and stopped passing is going back from lane D and going out of lane A, there is a risk of collision with the following vehicle, which is very dangerous. . However, by providing the re-entry lane E, such problems and dangers can be solved systematically.

  Here, as shown in FIG. 7 (this is an example of an exit toll booth), a vehicle incapable of wireless communication from lane A through lane E to lane B or C toll ticket issuing box 6 You may make it the structure which merges in the point before. In addition, lanes B and C are lanes for general vehicles, and a pass ticket issuing box 6 is provided respectively.

  Returning to FIG. 4, the antenna 3 in front of the gate includes a communication unit that communicates data with an ETC on-board unit mounted on the vehicle, and a determination unit that recognizes the received data and determines whether or not toll collection by ETC is possible. It has been.

  The guidance devices 4-1 and 4-2 are, for example, in the form of a breaker. When guiding to route D, the route D side breaker is opened and the route E side breaker is closed, and when guiding to route E, the route E is routed. There is a method of guiding by closing the route D side breaker by opening the E side breaker. In addition, it is possible to display in the form of a display panel and display characters such as “passable” and “impossible to pass” for each route, “↑” (arrow) for routes that can pass, and routes that cannot pass May display a symbol or a picture such as “×” (cross mark). Further, the reason for guiding to the route E such as “ETC unreadable” may be displayed. Moreover, you may use together a circuit breaker format and a display panel format.

  The pass ticket issuing box 10 is a manned or unmanned facility for collecting charges with cash or a magnetic card, and is currently installed at a toll booth on a highway.

  The guidance method of the vehicle guidance system of FIGS. 3 and 4 will be briefly described using the flow shown in FIG. 5 while paying attention to the functions of the plurality of vehicle detection devices 2a, 2b, 2c, and 2d shown in FIG. When the first vehicle detection device 2a detects the entry of the vehicle (step S02), the circuit breaker 1 is closed to leave a certain distance from the following vehicle (step S03). As will be described later, the breaker 1 does not open unless the vehicle detection device 2c or 2d detects the vehicle, so that the collision between the preceding vehicle and the following vehicle can be avoided and the preceding vehicle is prevented from traveling backward in the lane A. it can. When the second vehicle detection device 2b detects an approaching vehicle (step S05), it is confirmed that the vehicle has passed the antenna in front of the gate 3, and at this timing, it is determined whether communication is possible, communication is impossible or impossible. (Steps S06, S07). The determination time is fixed, so that a state in which the vehicle has not passed and a state in which wireless communication has not been performed although the vehicle has passed can be identified.

  If communication is possible, the guidance device 4-1 opens and is guided to the lane D and proceeds to the toll road 7 (step S08). On the contrary, if communication is impossible / impossible, the guiding device 4-2 opens and is guided to the lane E, and returns to the place where the lanes A, B, and C are selected again (step S13). Here, “communication impossible / impossible” includes a case where a general vehicle enters by mistake and a case where the ETC vehicle does not succeed in wireless communication for some reason.

  When the third vehicle detection device 2c detects an approaching vehicle (step S09), since this vehicle is escaping from the lanes A → D, the breaker 1 is opened (step S10). Similarly, the fourth vehicle detection device When 2d detects an approaching vehicle (step S14), the breaker 1 is opened (step S15) because it is getting out of the lanes A → E. As a result, when one vehicle enters the section of the vehicle detection devices 2c and 2d from the circuit breaker 1, this section becomes a kind of closed area, and the existence of only one vehicle is allowed. ing. For this reason, there is no collision between the preceding vehicle and the following vehicle in this closed area. As long as the ETC system is operating normally, the time during which the circuit breaker 1 is closed is the time required for the vehicle to pass the ETC gate 5 from the circuit breaker 1 and is only a few seconds. Stop travel is virtually secured.

  It is to be noted that the roadside antenna 3 and the ETC gate 5 are installed together at the location of the antenna 3 before the gate, and it is determined whether or not wireless communication is possible. May be executed at once.

  Moreover, although the above-mentioned Example is an entrance ticketing system, this invention is not limited to this, It can employ | adopt also in a simple collection system. In this case, such a guidance system may be provided at least at one location between the entrance and exit of the toll road.

  The guidance system shown in FIGS. 3 and 4 is executed by a computer (not shown) connected to each breaker, each vehicle detection device, the antenna in front of the gate, the ETC gate, and the like. The above-described guidance method is programmed, read into this computer, and executed. Further, this program is recorded on an appropriate recording medium. The present invention includes not only the above-described guidance system but also such a guidance method, a program for executing this guidance method, and a recording medium recording this program.

According to this embodiment, the following effects can be obtained.
(1) This embodiment can be realized only by preparing a new re-entry lane E without making a significant change to the conventional interchange.
(2) After entering the ETC lane, even if ETC wireless communication is disabled / impossible, the re-entry lane E is prepared so that no traffic jam occurs.
(3) When the vehicle detection device 2a detects an approaching vehicle, the circuit breaker 1 is closed. After that, the vehicle detection devices 2c and 2d cannot open the circuit breaker 1 unless an approaching vehicle is detected. Can be blocked.
(4) Furthermore, since one vehicle is limited between the circuit breaker 1 and the vehicle detection devices 2c and 2d, a collision accident can be avoided between the approaching vehicle and the following vehicle.

[Vehicle guidance system using ETC system for exit toll booth]
FIG. 6 shows a vehicle guidance system using an ETC system at an exit toll gate.

  The vehicle travels from the toll road 7 toward the general road 8, and a toll gate 9 is provided therebetween. Conventionally, three lanes were prepared at the toll booth. Lanes (A → D) are dedicated to ETC, and lanes B and C are for ordinary vehicles. In this embodiment, a new re-entry lane E is prepared.

  The vehicle guidance system using the ETC system for the exit toll gate in FIG. 6 is basically the same as that in FIGS.

  The guidance method of the vehicle guidance system of FIGS. 6 and 7 will be briefly described using the flow shown in FIG. 8 while paying attention to the functions of the plurality of vehicle detection devices 2a, 2b, 2c, and 2d shown in FIG. When the first vehicle detection device 2a detects entry of a vehicle (step S22), the circuit breaker 1 is closed so as to leave a certain distance from the following vehicle (step S23). When the second vehicle detection device 2b detects an approaching vehicle (step S25), it is confirmed that the vehicle has passed through the antenna in front of the gate 3, and at this timing, it is determined whether communication is possible or communication is impossible. (Steps S26 and S27). If communication is possible, the guidance device 4-1 opens and is guided to the lane D and proceeds to the general road 8. On the other hand, if communication is impossible / impossible, the guiding device 4-2 opens and is guided to the re-entry lane E, and returns to the place where the lanes A, B, and C are selected again. In addition, as shown in FIG. 7, you may make it guide to the general vehicle lane B or C. FIG.

  At this time, when the third vehicle detection device 2c detects an approaching vehicle (step S29), since this vehicle is escaping from the lane A → D, the circuit breaker 1 is opened (step S30). When the vehicle detection device 2d detects an approaching vehicle (step S34), the breaker 1 is opened (step S35) because it is getting out of the lanes A → E.

  Similarly, the guidance system of FIGS. 6 and 7 is executed by a computer (not shown) connected to each breaker, each vehicle detection device, the antenna in front of the gate, the ETC gate, and the like. The above-described guidance method is programmed, read into this computer, and executed. Further, this program is recorded on an appropriate recording medium. The present invention includes not only the above-described guidance system but also such a guidance method, a program for executing this guidance method, and a recording medium recording this program.

  According to this embodiment, the same effects as (1) to (4) described above can be obtained.

[Other application examples]
(Interchange with enhanced reverse entry prevention function)
However, in the embodiment described with reference to FIG. 4, it is not possible to prevent an illegal vehicle for non-payment from entering the ETC vehicle lane back from the exit of the ETC vehicle lane or the exit of the departure lane. Has the problem. In order to solve this, in the embodiment described below, reverse running prevention means is similarly provided for each of the lane D and the lane E by a combination of a breaker and a vehicle detection device.

  FIG. 9 is a modified example of FIG. 4 and is a diagram showing a configuration of an interchange with enhanced reverse entry prevention function. FIG. 10 is a flowchart for explaining a guidance method of the vehicle guidance system of FIG.

  9 is compared with that of FIG. 4, in addition to the closed section described in FIG. 4 (section of circuit breakers 1 to 4-1, 4-2), the closed section F (breaker 1) is compared. -2 to the section of the circuit breaker 4-1) and the closed section G (section of the circuit breaker 1-3 to the circuit breaker 4-2). As shown in FIG. 9, in order to form a closed section F, a breaker 1-2, a vehicle detection device 2e, and a closed section sensor 16 are newly provided, and in order to form a closed section G, a new breaker 1 is provided. -3, a vehicle detection device 2f, a closed section sensor 17, and a closed section sensor 18 are further provided.

  When the flow of FIG. 10 is compared with that of FIG. 8, the difference is that steps S50 to 54, 56, 59 to 62 are newly added to FIG.

  This embodiment will be briefly described with reference to FIGS. 9 and 10. When the vehicle enters the lane D, when the vehicle detection device 2c detects the vehicle (step S49), the circuit breaker 4-1 is closed and blocked. The machine 1-2 is opened (step S50), and then the circuit breaker 4-1 is kept closed until the pre-gate antenna 3 recognizes and determines the following vehicle (step S48). When the vehicle detection device 2e detects the vehicle (step S52), the circuit breaker 1-2 is closed (step S53) to prevent an unauthorized vehicle from entering backward from the exit of the lane D. When the vehicle section sensor 16 confirms that there is no vehicle in the closed section F (step S54), the circuit breaker 1 is opened (step S55), and the following vehicle can enter. In the unlikely event that another illegal vehicle makes a reverse entry with a vehicle leaving the closed section F, if the closed section sensor 16 determines that there is a vehicle in the closed section F (step S54), a notification to the monitoring center is made. Take action to prevent any further unauthorized vehicles from entering.

  The same applies to Lane E. When the vehicle enters the lane E, when the vehicle detection device 2d detects the vehicle (step S58), the circuit breaker 4-2 is closed and the circuit breaker 1-3 is opened (step S59), and then the antenna 3 before the gate follows. Until the vehicle is recognized and judged (step S57), the circuit breaker 4-2 is kept closed. When the vehicle detection device 2f detects the vehicle (step S60), the circuit breaker 1-3 is closed (step S61) to prevent the unauthorized vehicle from entering backward from the exit of the lane E. When the vehicle section sensor 17 confirms that there is no vehicle in the closed section G (step S62), the circuit breaker 1 is opened (step S63), and the following vehicle can enter. In the unlikely event that another fraudulent vehicle makes a reverse entry with a vehicle leaving the closed section F, if the closed section sensor 17 determines that there is a vehicle in the closed section G (step S62), a notification to the monitoring center is made. Take action to prevent any further unauthorized vehicles from entering.

  Further, if necessary, a closed section sensor 18 may be provided to finally confirm the presence or absence of a vehicle in lane A.

  The video taken by the closed section sensor is displayed on a monitor of a monitoring center (not shown), and a supervisor monitors it. Here, the closed section sensor may be a normal visible camera, an infrared camera, or a combination of both as required. When an infrared camera is used, the high temperature of the engine unit of the vehicle is detected, so that even if a plurality of vehicles enter at the same time, these can be identified.

  It should be appreciated that this embodiment can be applied to both entrance and exit interchanges.

  According to the vehicle guidance system of the present invention, an ordinary vehicle can be prevented from entering and only an ETC vehicle can be targeted. Therefore, an interchange can be unmanned and an economic effect can be expected.

(Vehicle guidance systems such as paid parking lots)
In addition, the present invention is not limited to a toll gate that connects a toll road and a general road, but is installed in an area that requires a fee for use, such as a toll parking lot, a toll car wash, or a drive-in theater. You can also. FIG. 12 shows an embodiment of a pay parking lot in which the vehicle guidance system of the present invention is introduced.

  From the entrance, the vehicle (ETC car and general car) 14 enters the parking lot through the circuit breaker 1. It is determined whether or not ETC communication is possible by the antenna 3 before the gate, and if possible, it is guided in the direction of the route D. After parking, go out from the ETC car exit. If wireless communication is not possible / impossible, the user is guided in the direction of route E and receives an admission ticket in which the admission time is described at the admission ticketing office 15. After parking, pay the fee at the toll collection station 6 and go outside from the exit for general vehicles.

  In this case, since it is possible to omit the involvement of human hands for the ETC vehicle, it is possible to save labor costs.
