Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle guidance system, and more specifically to a vehicle guidance system that safely guides a vehicle that is used at an ETC vehicle entrance/exit installed at the entrance/exit of a toll road.

In recent years, an ETC system (Electronic Toll Collection System: non-stop automatic toll payment system) has been installed at toll gates of toll roads. As shown in FIG. 1, the ETC system uses wireless communication between the roadside antennas 3 and 5 installed at the toll gate and the vehicle-mounted device 20 mounted on the vehicle 14 to automatically settle the toll. It is a system that allows non-stop passage through toll booths. The ETC system is basically installed on the dashboard of the vehicle 14, etc., and includes an on-vehicle device 20, which is a wireless device that communicates information necessary for toll calculation, and a toll payer, which is inserted into and used by the on-vehicle device 20. It consists of an IC card (ETC card) 21 in which contract information is recorded, roadside antennas (ETC roadside wireless devices) 3, 5, etc., which are installed on the lanes of the tollbooth and perform wireless communication with the vehicle-mounted device 20. It is Of these, the vehicle-mounted 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 ticket issuing system used on many toll roads, entrance information is wirelessly transmitted from the roadside antennas 3 and 5 to the vehicle-mounted device 20 at the entrance toll booth, and after traveling on the toll road 7, At the exit toll booth, entrance information is wirelessly transmitted from the vehicle-mounted device 20 to the roadside antennas 3, 5, the toll calculation computer provided separately calculates the toll, and the toll information is directed from the roadside antennas 3, 5 to the vehicle-mounted device 20. Transmitting by radio. In the simple collection system of uniform tolls such as urban expressways, it is sufficient that such an ETC is installed in at least one place between the entrance and the exit. The number of roadside antennas 3 and 5 may be one or two or more.

The benefits of ETC are wide-ranging, including alleviation of congestion at toll gates, environmental improvement due to reduced noise and exhaust gas emissions due to fewer stops and departures at toll gates, convenience associated with cashless payments, and reduced management costs. Expected to be effective.

However, at present, not all vehicles are compatible with the ETC system, so there are lanes for ETC vehicles labeled "ETC exclusive" and ETC vehicles labeled "general ETC" in the lanes of toll gates on toll roads. There are lanes that can be used by general vehicles, and lanes that cannot use the ETC system that are marked "general". Therefore, a general vehicle may erroneously enter the dedicated lane for ETC vehicles. In this application, "ETC vehicle" refers to a vehicle that can collect tolls by ETC, and "general vehicle" refers to a vehicle that cannot use the ETC system.

Furthermore, even if it is an ETC vehicle, it may happen that the vehicle-mounted device cannot communicate normally with the roadside antenna. For example, there are cases such as non-insertion, incomplete insertion, or just-before insertion of the ETC card into the vehicle-mounted device.

In such a case, the opening and closing bar will be lowered and you will not be able to proceed. As a result, traffic jams at the toll booths are exacerbated, defeating the original purpose of ETC.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals are given to the same elements shown in the drawings, and redundant explanations are omitted.

First, the vehicle guidance system using the ETC system used at the entrance toll gate of the toll road will be explained, then the vehicle guidance system used at the exit toll gate, and further application examples (interchange with enhanced reverse run prevention function, smart interchanges, parking lots, etc.).

[Vehicle guidance system using ETC system for entrance tollgate]
FIG. 3 shows a vehicle guidance system using an ETC system used at an entrance tollgate.

A vehicle travels from a general road 8 toward a toll road 7, and a toll booth 9 is provided in between. Conventionally, the toll gate 9 has three lanes. Lane (A→D) is exclusively for ETC, and lanes B and C are for general vehicles. In this embodiment, a lane E (also referred to as a "re-entry lane") newly branched from A is provided. Here, the route A→D is a route that passes through the ETC gate 5 and proceeds to the toll road 7, 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 for wireless communication with the vehicle-mounted equipment. FIG. 4 shows details of lanes A→D and A→E, along which further discussion is provided. A vehicle enters from a general road 8, passes through a pre-opened barrier 1, is detected by a vehicle detection device 2a, and faces a roadside antenna (antenna in front of a gate) 3 for determining whether or not wireless communication is possible. It passes through and is detected by the vehicle detection device 2b.

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

When it is determined that wireless communication with the front-of-gate antenna 3 is impossible or impossible, the guidance device 4-2 is opened while the guidance device 4-1 remains closed, the vehicle advances to lane E, and passes the vehicle detection device 2d side. and return to the point where one of lanes A, B, and C is selected again. Conventionally, since there was no re-entry lane E, when the opening/closing bar 4-1 was lowered and it became impossible to proceed, it was necessary to stop the vehicle and call an attendant using an interphone or the like. As a result, traffic congestion at the toll gate 9 is aggravated, and the original purpose of ETC cannot be achieved. In addition, if a vehicle blocked from traffic by the lowering of the opening/closing bar 4-1 backs up from Lane D and tries to exit from Lane A, there is a risk of colliding with the following vehicle, which is extremely 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 tollgate), a vehicle with or without wireless communication is from lane A, passes through lane E, and passes through lane B or C toll ticket issuing box 6. It may be configured such that it merges with an earlier point. Note that lanes B and C are lanes for general vehicles and are provided with toll ticket issuing boxes 6, respectively.

Returning to FIG. 4, the front-of-gate antenna 3 is provided with communication means for communicating data with the ETC on-board device mounted on the vehicle and determination means for recognizing the received data and determining whether toll collection by ETC is possible. It is

The guiding devices 4-1 and 4-2 are, for example, in the form of crossing gates. There is a method of opening the barrier on the E side and closing the barrier on the route D side. In addition, in the form of a display panel, it is possible to display characters such as "passable" and "impassable" for each route, and "↑" (arrow) for passable routes and impassable routes may display a symbol such as "x" (cross mark) or a picture. Also, the reason for guiding to the route E such as "ETC cannot be read" may be displayed. Also, the circuit breaker type and the display panel type may be used together.

A toll ticket issuing box 10 is a manned or unmanned facility for collecting tolls with cash, magnetic cards, etc., and is currently introduced at expressway toll booths.

The guidance method of the vehicle guidance system shown in 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 a vehicle (step S02), the gate 1 is closed to keep a certain distance from the following vehicle (step S03). As will be described later, the gate 1 does not open unless the vehicle detection device 2c or 2d detects a vehicle, thereby avoiding collision between the preceding vehicle and the following vehicle, and preventing the preceding vehicle from traveling in the opposite direction on lane A. can. When the second vehicle detection device 2b detects an entering vehicle (step S05), it confirms that the vehicle has passed the front gate antenna 3, and determines at this timing whether communication is possible or communication is impossible/impossible. (Steps S06, S07). Judgment timing is determined so that it is possible to discriminate between a state in which no vehicle has passed and a state in which radio communication has not been performed even though the vehicle has passed.

If communication is possible, the guidance device 4-1 is opened and the vehicle is guided to the lane D to proceed to the toll road 7 (step S08). Conversely, if the communication is disabled/impossible, the guidance device 4-2 is opened and the user is guided to lane E, and returns to the place where lanes A, B, and C are selected again (step S13). Here, "communication disabled/impossible" includes cases where a general vehicle enters by mistake and cases where an ETC vehicle fails to communicate wirelessly for some reason.

When the third vehicle detection device 2c detects an entering vehicle (step S09), this vehicle is exiting lane A→D, so the gate 1 is opened (step S10). When the vehicle 2d detects an entering vehicle (step S14), it is escaping from lane A→E, so the gate 1 is opened (step S15). As a result, when one vehicle enters the section between the vehicle detection devices 2c and 2d from the gate 1, this section becomes a kind of closed area, and only one vehicle is allowed to exist. ing. Therefore, collisions between preceding and following vehicles do not occur in this closed area. As long as the ETC system is working normally, the time that the barrier 1 is closed is the time from the barrier 1 until the vehicle passes through the ETC gate 5, which is only a few seconds. Stop running is practically secured.

The front gate antenna 3, which is a roadside antenna, and the ETC gate 5 are installed together at the location of the front gate antenna 3 to determine whether or not wireless communication is possible and, if possible, to transmit entrance information. can be run at once.

Further, although the above-described embodiment is an entrance ticket issuing system, the present invention is not limited to this, and can also be employed in a simple collection system. In this case, at least one such guiding system should be installed between the entrance and 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, gate front antenna, ETC gate, and the like. The guidance method described above is programmed, read into this computer, and executed. Furthermore, this program is recorded on a suitable recording medium. The present invention includes not only the guidance system described above, 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 are obtained.
(1) This embodiment can be realized by simply preparing a new re-entry lane E without making any drastic changes to the conventional interchange.
(2) After entering the ETC lane, even if the ETC wireless communication is disabled or disabled, the re-entry lane E is prepared, so traffic congestion does not occur.
(3) When the vehicle detection device 2a detects an entering vehicle, the gate 1 is closed, and after that, the gate 1 cannot be opened unless the vehicle detection devices 2c and 2d detect the entering vehicle, thereby preventing the entering vehicle from illegally traveling in the opposite direction. can be prevented.
(4) Furthermore, since the number of vehicles between the gate 1 and the vehicle detection devices 2c and 2d is limited to one, collision accidents between the entering vehicle and the following vehicle can be avoided.

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

A vehicle advances from a toll road 7 toward a general road 8, and a toll gate 9 is provided in between. Conventionally, a toll gate has three lanes. Lane (A→D) is exclusively for ETC, and lanes B and C are for general vehicles. In this embodiment, a re-entry lane E is newly provided.

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

Focusing on the functions of the plurality of vehicle detection devices 2a, 2b, 2c, and 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 gate 1 is closed to keep a certain distance from the following vehicle (step S23). When the second vehicle detection device 2b detects an entering vehicle (step S25), it confirms that the vehicle has passed the front gate antenna 3, and determines at this timing whether communication is possible or communication is impossible/impossible. (Steps S26, S27). If 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 disabled/impossible, the guidance device 4-2 is opened and the passenger is guided to the re-entry lane E, and returns to the place where lanes A, B, and C are selected again. Alternatively, the vehicle may be guided to the general vehicle lane B or C as shown in FIG.

At this time, when the third vehicle detection device 2c detects an entering vehicle (step S29), this vehicle is exiting lane A→D, so the gate 1 is opened (step S30). When the vehicle detection device 2d detects an entering vehicle (step S34), the barrier 1 is opened (step S35) because the vehicle is escaping from lane A→E.

Similarly, the guidance system of FIGS. 6 and 7 is executed by a computer (not shown) connected to each circuit breaker, each vehicle detection device, an antenna in front of the gate, an ETC gate, and the like. The guidance method described above is programmed, read into this computer, and executed. Furthermore, this program is recorded on a suitable recording medium. The present invention includes not only the guidance system described above, 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 improved reverse entry prevention function)
However, in the embodiment described with reference to FIG. 4, it is not possible to prevent an illegal vehicle for the purpose of non-payment of tolls from entering the ETC lane backwards from the exit of the ETC lane or the departure lane. It has a problem. In order to solve this problem, in the embodiment described below, each of lane D and lane E is similarly provided with reverse-running prevention means by a combination of a barrier and a vehicle detection device.

FIG. 9 is a modification of FIG. 4, showing the configuration of an interchange with enhanced reverse entry prevention function. FIG. 10 is a flow chart explaining the guidance method of the vehicle guidance system of FIG.

Comparing the configuration of the interchange in FIG. 9 with that in FIG. -2 to barrier 4-1) and closed section G (section from barrier 1-3 to barrier 4-2). As shown in FIG. 9, in order to form the closed section F, a new circuit breaker 1-2, a vehicle detection device 2e, and a closed section sensor 16 are newly provided. -3, a vehicle detection device 2f and a closed section sensor 17 are provided, and a closed section sensor 18 is also provided.

Comparing the flow of FIG. 10 with that of FIG. 8, the substantial difference is that steps S50 to S54, 56, and 59 to 62 are newly added to FIG.

Briefly describing this embodiment with reference to FIGS. 9 and 10, when a vehicle enters lane D and the vehicle detection device 2c detects the vehicle (step S49), the gate 4-1 is closed to block the vehicle. The gate 1-2 is opened (step S50), and the barrier 4-1 is kept closed until the gate front antenna 3 recognizes and judges the following vehicle (step S48). When the vehicle detection device 2e detects a vehicle (step S52), the gate 1-2 is closed (step S53) to prevent unauthorized vehicles from entering from the lane D exit. When the vehicle section sensor 16 confirms that there is no vehicle in the closed section F (step S54), the gate 1 is opened (step S55) to allow the following vehicle to enter. Even in the unlikely event that another unauthorized vehicle enters the closed section F while passing another vehicle, if the closed section sensor 16 determines that the vehicle is in the closed section F (step S54), it will notify the monitoring center. Take action to prevent further unauthorized vehicles from entering.

The same is true for lane E. When a vehicle enters the lane E, when the vehicle detection device 2d detects the vehicle (step S58), the barrier 4-2 is closed and the barrier 1-3 is opened (step S59). The gate 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), the barrier 1-3 is closed (step S61) to prevent an unauthorized vehicle from entering from the lane E exit. When the vehicle section sensor 17 confirms that there is no vehicle in the closed section G (step S62), the gate 1 is opened (step S63) to allow the following vehicle to enter. Even in the unlikely event that another unauthorized vehicle enters the closed section F while passing another vehicle, if the closed section sensor 17 determines that the vehicle is in the closed section G (step S62), it will notify the monitoring center. Take action to prevent further unauthorized vehicles from entering.

Furthermore, 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 captured by the closed section sensor is displayed on a monitor in a monitoring center (not shown) and monitored by a monitoring staff. Here, the closed section sensor can be a normal visible camera, an infrared camera, or a combination of both, as required. If an infrared camera is used, the high temperature of the engine part of the vehicle can be detected, so even if multiple vehicles approach at the same time, they can be identified.

It should be noted that this embodiment is applicable to both entrance and exit interchanges.

(Vehicle guidance system for smart interchanges)
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 (tollbooth) exclusively for ETC vehicles, which is connected to general roads by installing ETC gates in parking areas and service areas of expressways. It is It is characterized by being able to be constructed and managed at a lower cost than 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 always be present in case a general vehicle enters the smart interchange and gets stuck.

As shown in FIG. 11, a parking-area or service-area 11 is provided between the general road 8 and the toll road 7 . There is an entrance toll gate 12 for entering the toll road 7 from the general road 8 and an exit toll gate 13 for exiting from the toll road 7 to the general road 8. - 特許庁Roles of lanes (A→D) and (A→E) at the entrance tollgate 12, and lanes (A→D) and (A→E) at the exit tollgate 13, except that there are no general vehicle lanes B and C. The role of is the same as that of FIGS.

According to the vehicle guidance system of the present invention, entry of general vehicles can be blocked and only ETC vehicles can be targeted.
