Description

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

In recent years, an ETC system (Electronic Toll Collection System) has been installed at toll gates on toll roads. As shown in FIG. 1, the ETC system automatically sets the toll by wireless communication between the roadside antennas 3 and 5 installed at the tollgate gate and the vehicle-mounted device 20 mounted on the vehicle 14. It is a system that allows non-stop traffic toll booths. The ETC system is basically installed on the dashboard of the vehicle 14 or the like, and is mounted on the vehicle-mounted device 20 that is a wireless device that communicates information necessary for fee calculation, and is used by being inserted into the vehicle. Consists of an IC card (ETC card) 21 in which the contract information is recorded and a roadside antenna (ETC roadside wireless device) 3, 5 etc. that is installed on the lane (lane) of the tollgate and performs wireless communication with the vehicle-mounted device 20. Has been done. Among them, the in-vehicle device 20 is sold to a user by a private company, the credit company lends the ETC card 21 to the user, and the roadside antennas 3 and 5 are installed by a toll road company.

As shown in FIG. 2, in the entrance ticketing system used on 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 in-vehicle device 20 wirelessly transmits the entrance information to the roadside antennas 3 and 5, the charge calculation is performed by a separately provided charge calculation computer, and the charge information is directed from the roadside antennas 3 and 5 to the on-vehicle device 20. It is transmitting wirelessly. In the case of a simple toll collection method with a uniform toll such as an expressway in a city, such an ETC may be installed at at least one place between the entrance and the exit. The roadside antennas 3, 5 may be one or two or more.

ETC has a wide range of benefits such as eliminating congestion at tollgates, reducing noise by reducing the number of stops/departures at tollgates, improving the environment by reducing exhaust gas, convenience and management costs associated with cashlessness, etc. The effect is expected.
The name of the invention, "High Speed", was filed on November 10, 1994 (Japanese Patent Application No. 6-286508) and published on May 31, 1996 (Japanese Patent Application Laid-Open No. 8-138095). There is a road toll collection system.

This prior application discloses a technology regarding toll collection when exiting from a toll road to a general road (paragraph 0036), and toll collection is performed between the wireless IC card sensor 14 and the wireless IC card.

However, not all vehicles are compatible with the ETC system at this time, so some ETC vehicle-only lanes labeled "ETC only" and some ETC vehicles labeled "ETC general" are available in the toll gate lanes. Lanes in which ordinary cars can also pass are mixed, and lanes in which the ETC system labeled "general" cannot be used are mixed. For this reason, there is a possibility that an ordinary vehicle may accidentally enter the ETC vehicle dedicated lane. In this application, "ETC vehicle" means a vehicle that can collect charges by ETC, and "general vehicle" means a vehicle that cannot use the ETC system.

Further, even in the case of an ETC vehicle, the case where the vehicle-mounted device cannot normally communicate with the roadside antenna may occur. For example, this is the case where the ETC card is not inserted into the vehicle-mounted device, is incompletely inserted, or is just inserted.

In such a case, the open/close bar will go down and you will not be able to proceed. Therefore, it is necessary to stop the vehicle and call an attendant by the intercom. This promotes traffic congestion at the toll booth, which defeats the original purpose of ETC. In addition, when a vehicle whose opening/closing bar has been lowered to stop traveling backtracks from the lane and tries to get out, it may collide with a following vehicle, which is extremely dangerous.

However, the above-mentioned Patent Document 1 makes no mention of providing a safe vehicle guidance system as described later in the vehicle guidance system using the ETC system.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. The same elements as those shown in the drawings are designated by the same reference numerals, and a duplicate description will be omitted.

First, we will explain the vehicle guidance system that uses the ETC system used at the toll gates of toll roads, and then the vehicle guidance system that will be used at the exit toll gates, as well as application examples (interchanges with enhanced reverse running prevention functions, smart Interchanges, parking lots, etc.) will be explained.

[Vehicle guidance system using ETC system for entrance toll gate]
FIG. 3 shows a vehicle guidance system using the ETC system used at the 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 booth 9 was provided with three lanes. Lanes (A→D) are for ETC only, and lanes B and C are for ordinary vehicles. In this embodiment, a lane E (also referred to as a “re-entry lane”) that newly branches from A is prepared. Here, the route A→D is a route that goes through the ETC gate 5 to the toll road 7, and the route A→E is a lane for re-entry to the toll gate 9.

The lanes A to D are basically provided with roadside antennas 3 and 5, and perform wireless communication with the vehicle-mounted device. FIG. 4 shows the details of lanes A→D and A→E, and will be described further along with this. The vehicle enters from the general road 8, passes through the pre-opened circuit breaker 1, is detected by the vehicle detection device 2a, and is on the side of the roadside antenna (antenna in front of the gate) 3 for determining whether or not wireless communication is possible. It passes and is detected by the vehicle detection device 2b.

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

When it is determined that the wireless communication with the front-gate antenna 3 is impossible or impossible, the guidance device 4-1 is opened and the guidance device 4-2 is opened. Go back to the point where you will select one of lanes A, B, or C again. Conventionally, since there is no re-entry lane E, when the opening/closing bar 4-1 goes down and the vehicle cannot proceed, it is necessary to stop the vehicle and call an attendant by an intercom or the like. As a result, the congestion at the toll booth 9 is promoted, and the original purpose of ETC cannot be achieved. Further, when a vehicle whose opening/closing bar 4-1 has been lowered and is blocked from traveling back from lane D and trying to leave 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 systematically resolved.

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

Returning to FIG. 4, the antenna 3 in front of the gate is provided with a communication means for communicating data with an ETC vehicle-mounted device mounted on the vehicle and a determination means for recognizing the received data and determining whether the charge can be collected by ETC. Has been.

The guidance devices 4-1 and 4-2 are, for example, in the form of a circuit breaker. When guiding to the route D, the circuit breaker on the route D side is opened, the circuit breaker on the route E side is closed, and the route is guided to the route E. There is a method of opening the E side breaker and closing the route D side breaker for guidance. In addition, the display panel may be used to display characters such as “passable” and “impossible” on each route. “↑” (arrow) indicates a passable route, and “impossible” indicates a passable route. May display symbols or pictures such as "x" (cross mark). Further, the reason for guiding to the route E such as "ETC unreadable" may be displayed. Further, the circuit breaker type and the display panel type may be used together.

The pass ticket issuing box 10 is a manned or unmanned facility for collecting tolls with cash, magnetic cards, etc., and is currently installed at toll gates on expressways.

While focusing on the functions of the plurality of vehicle detection devices 2a, 2b, 2c, 2d shown in FIG. 4, the guidance method of the vehicle guidance system of FIGS. 3 and 4 will be briefly described using the flow 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 constant distance from the following vehicle (step S03). As will be described later, the circuit breaker 1 does not open unless the vehicle detection device 2c or 2d detects the vehicle, so that a collision between the preceding vehicle and the following vehicle can be avoided, and the preceding vehicle is prevented from traveling in the lane A in the reverse direction. it can. When the second vehicle detection device 2b detects an approaching vehicle (step S05), it is confirmed that the vehicle has passed through the front gate antenna 3, and it is determined at this timing whether communication is possible or communication is impossible or impossible. (Steps S06, S07). The determination time is fixed so that the state where the vehicle is not passing and the state where the vehicle is passing but the wireless communication is not performed can be distinguished.

If the communication is possible, the guidance device 4-1 opens and the vehicle is guided to the lane D to proceed to the toll road 7 (step S08). On the contrary, if the communication is impossible/impossible, the guiding device 4-2 is opened and the vehicle is guided to the lane E and returns to the place where the lanes A, B and C are selected again (step S13). Here, the “communication disabled/impossible” includes a case where a general vehicle erroneously enters 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), the vehicle is about to escape from lanes A→D, so the circuit breaker 1 is opened (step S10). Similarly, the fourth vehicle detection device When 2d detects an approaching vehicle (step S14), it is trying to open the circuit breaker 1 (step S15) because it is exiting from lanes A to E. As a result, when one vehicle enters the section of the vehicle detection devices 2c, 2d from the circuit breaker 1, this section becomes a kind of closed area, and only one vehicle is allowed to exist. ing. Therefore, no collision between the preceding vehicle and the following vehicle occurs 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 it takes for the vehicle to pass through the circuit breaker 1 and the ETC gate 5, and is only a few seconds. Stop driving is virtually ensured.

The front gate antenna 3 and the ETC gate 5, which are roadside antennas, are installed together at the location of the front gate antenna 3, and it is determined whether or not wireless communication is possible. May be executed at once.

Further, although the above-described embodiment is the entrance ticket issuing system, the present invention is not limited to this and can be adopted in the simple collection system. In this case, such a guidance system may be provided at at least one place between the entrance and the exit of the toll road.

The guidance system of FIGS. 3 and 4 is executed by a computer (not shown) connected to each circuit breaker, each vehicle detection device, front gate antenna, ETC gate, and the like. The guiding method described above is programmed, read into this computer, and executed. Furthermore, 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 the guidance method, and a recording medium recording the program.

According to this embodiment, the following effects can be obtained.
(1) The present embodiment can be realized by newly preparing the re-entry lane E without making a large change to the conventional interchange.
(2) After entering the ETC lane, even if the ETC wireless communication is disabled or impossible, the re-entry lane E is prepared, so that the traffic jam does not occur.
(3) When the vehicle detection device 2a detects an approaching vehicle, the circuit breaker 1 is closed, and when the vehicle detection devices 2c and 2d do not detect the approaching vehicle, the circuit breaker 1 cannot be opened. Can be stopped.
(4) Furthermore, since the number of vehicles between the circuit breaker 1 and the vehicle detection devices 2c and 2d is limited, a collision accident between the approaching vehicle and the following vehicle can be avoided.

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

The vehicle travels from the toll road 7 toward the general road 8, and a toll gate 9 is provided therebetween. Traditionally, toll booths had three lanes. Lanes (A→D) are for ETC only, and lanes B and C are for ordinary vehicles. In this embodiment, a re-entry lane E is newly 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.

While focusing on the functions of the plurality of vehicle detection devices 2a, 2b, 2c, 2d shown in FIG. 6, the guidance method of the vehicle guidance system of FIGS. 6 and 7 will be briefly described using the flow shown in FIG. When the first vehicle detection device 2a detects the entry of a vehicle (step S22), the circuit breaker 1 is closed to leave a constant 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 front gate antenna 3, and it is determined at this timing whether communication is possible or communication is impossible or impossible. (Steps S26, S27). If the communication is possible, the guidance device 4-1 opens and the vehicle is guided to the lane D to proceed to the general road 8. On the contrary, if the communication is impossible/impossible, the guidance device 4-2 is opened and the vehicle is guided to the re-entry lane E, and returns to the place where the lanes A, B and C are selected again. As shown in FIG. 7, the vehicle may be guided to the general vehicle lane B or C.

At this time, when the third vehicle detection device 2c detects an approaching vehicle (step S29), the vehicle is about to escape from lanes A→D, so the circuit breaker 1 is opened (step S30). When the vehicle detection device 2d detects an approaching vehicle (step S34), the circuit breaker 1 is opened (step S35) because the vehicle is exiting from the lanes A to 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, front gate antenna, ETC gate, and the like. The guiding method described above is programmed, read into this computer, and executed. Furthermore, 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 the guidance method, and a recording medium recording the program.

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

[Other application examples]
(Interchange with enhanced reverse approach prevention function)
However, in the embodiment described with reference to FIG. 4, it is not possible to prevent a fraudulent vehicle for the purpose of non-payment of charges from going back to the ETC vehicle lane from the exit of the ETC vehicle lane or the exit of the departure lane. There is a problem. In order to solve this, in the embodiment to be described next, each of the lane D and the lane E is similarly provided with reverse running preventing means by a combination of a circuit breaker and a vehicle detection device.

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

Comparing the configuration of the interchange of FIG. 9 with that of FIG. 4, in addition to the closed section (section of the circuit breaker 1 to the circuit breakers 4-1 and 4-2) described in FIG. 4, a closed section F (circuit breaker 1 -2-section of the circuit breaker 4-1) and a 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 circuit 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 circuit breaker 1 is newly provided. -3, a vehicle detection device 2f, a closed section sensor 17 are provided, and further a closed section sensor 18 is provided.

Comparing the flow of FIG. 10 with that of FIG. 8, the difference is substantially that steps S50 to 54, 56, and 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 and the vehicle detection device 2c detects the vehicle (step S49), the circuit breaker 4-1 is closed to shut off the vehicle. The machine 1-2 is opened (step S50), and then the circuit breaker 4-1 is kept closed until the antenna 3 in front of the gate recognizes and recognizes the following vehicle (step S48). When the vehicle detection device 2e detects a vehicle (step S52) and closes the circuit breaker 1-2 (step S53), an unauthorized vehicle is prevented from reversely entering 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. Even if another fraudulent vehicle reversely approaches the 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), it notifies the monitoring center. Take action to prevent unauthorized vehicles from entering further.

The same applies to lane E. When the vehicle enters the lane E and 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 front gate antenna 3 follows. The circuit breaker 4-2 is kept closed until the vehicle is recognized and determined (step S57). When the vehicle detection device 2f detects a vehicle (step S60) and closes the circuit breaker 1-3 (step S61), an unauthorized vehicle is prevented from reversely entering 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. Even if another fraudulent vehicle reversely approaches the vehicle leaving the closed section F, the closed section sensor 17 determines that there is a vehicle in the closed section G (step S62), and notifies the monitoring center. Take action to prevent unauthorized vehicles from entering further.

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

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

(Smart Interchange vehicle guidance system)
FIG. 11 shows a modification, specifically, an example in which the vehicle guidance system of the present invention is introduced into a smart interchange. A smart interchange is an interchange (toll gate) exclusively for ETC vehicles that installs an ETC gate in the parking-area or service-area of the highway and connects it to general roads. It is planned to be introduced experimentally from 2004. Has been done. It is characterized by low cost construction and management compared to conventional interchanges, and is expected to improve the convenience of expressways and revitalize surrounding areas. However, it is not economical because a staff member must be stationed in case a general car gets into a smart interchange and gets stuck.

As shown in FIG. 11, a parking area or a service area 11 is provided between the general road 8 and the toll road 7. There is an entrance toll booth 12 for entering the toll road 7 from the general road 8 and an exit toll booth 13 for exiting from the toll road 7 to the general road 8 on the contrary. Except that there are no general vehicle lanes B and C, the roles of lanes (A→D) and (A→E) at the entrance toll gate 12, and lanes (A→D) and (A→E) at the exit toll gate 13 Has the same role as that of FIGS. 3, 4, 6 and 7.

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 system for paid parking lots, etc.)
Further, the present invention is not limited to a toll gate connecting a toll road and an ordinary road, and is installed in an area where a fee is required for use, such as a toll parking lot, a toll car wash, or a drive-in theater. You can also FIG. 12 is an example of a pay parking lot in which the vehicle guidance system of the present invention is introduced.

From the entrance, a vehicle (ETC vehicle and ordinary vehicle) 14 enters the parking lot through the breaker 1. It is determined by the front gate antenna 3 whether ETC communication is possible, and if possible, the vehicle is guided in the direction of route D. After parking, go out from the exclusive exit for ETC cars. If wireless communication is impossible/impossible, the vehicle is guided in the direction of route E, and the admission ticket with the admission time is received at the admission ticket issuing office 15. After parking, pay the fee at the toll collection point 6 and go out through the exit for general vehicles.

In this case, it is possible to save labor costs because it is possible to omit human involvement with the ETC vehicle.

Similarly, the system of FIGS. 9, 11 and 12 is executed by a computer (not shown) connected to each circuit breaker, each vehicle detection device, front gate antenna, ETC gate and the like. The guiding method described above is programmed, read into this computer, and executed. Furthermore, 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 the guidance method, and a recording medium recording the program.
