DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection system used for toll roads such as expressways and toll bridges.

[0002]

2. Description of the Related Art Generally, as a toll collection system for toll payment on a toll road, a so-called open system having only one checkpoint provided for payment of tolls, a checkpoint system, and the like. , A so-called closed system having at least two locations.

The closing system is applied to, for example, a highway for traveling a long distance, and issues a toll ticket at an entrance gate through which the vehicle passes when entering the highway. This is an entrance ticketing / exit collection system that collects a toll according to the distance that the vehicle has traveled on the highway and the type of vehicle at the exit gate that passes when exiting the road.

[0004] The open system is applied to, for example, toll roads near the Tokyo metropolitan area (such as the Tokyo Metropolitan Expressway) and toll bridges, and collects a certain toll at an entrance gate through which vehicles enter the toll road. There is no gate at the exit of
This is a system that allows vehicles to pass as it is.

As a specific example of the above-mentioned closed system, there is a magnetic card type toll collection system. This magnetic card type toll collection system includes, for example, an entrance gate roadside machine installed at an entrance gate of an interchange on a highway and an exit gate roadside machine installed at an exit gate. The main equipment of the entrance gate roadside machine is an automatic toll ticket issuing device for issuing a toll ticket of a magnetic card. The exit gate roadside machine includes a receipt issuing machine, a pass ticket reader, a control device, and the like.

[0006] In this magnetic card type toll collection system, usually, at an entrance gate where a vehicle enters, an automatic toll ticket issuing device transmits information on the interchange of the entrance gate, that is, entrance gate information for specifying the entrance gate. The recorded magnetic card is issued as a toll ticket, and at the exit gate, the toll ticket held by the driver of the vehicle is passed through a toll ticket reader, and the entrance information magnetically recorded on the toll ticket is read out to pay a toll. The calculated amount is presented to the driver, and a toll is collected by cash, a highway card, or the like.

In the case of this magnetic card type toll collection system, at the entrance gate, the procedure is only to receive a passport from the automatic ticket issuance device. Therefore, the area near the entrance gate is not so crowded, but at the exit gate. However, since there are extremely many artificial operations such as the passing of toll tickets and receipts and the collection of tolls, there is a problem that as the number of vehicles using the highway increases, the area near the exit gate becomes crowded.

Therefore, in recent years, the introduction of a new technique for alleviating this congestion has been started. As one of the new technologies, a vehicle-mounted device having a wireless communication function and an IC card capable of storing various information is detachably mounted on a vehicle. It is possible to introduce a wireless card type toll collection system that performs wireless communication with the communication devices provided at the gates and settles tolls together with the magnetic card type toll collection system described above. It is considered.

As described above, when introducing a toll collection system using both a magnetic card and a wireless card, a vehicle equipped with a vehicle-mounted device (hereinafter referred to as an <ETC vehicle>) and a vehicle not equipped with a vehicle-mounted device (hereinafter referred to as an ETC vehicle). <Non-ETC vehicles>)
Because it will pass through the entrance gate and the exit gate,
It is necessary to collect tolls for each vehicle. That is, at the entrance gate, a toll such as a magnetic card is issued for a non-ETC vehicle, and for an ETC vehicle, the I / O set in the on-vehicle device in the ETC vehicle by wireless communication using a communication device.
Control is performed so that entrance gate information is stored in the C card. On the other hand, at the exit gate, a toll ticket is received from the driver of the non-ETC vehicle as usual, processed by the toll reader, and the toll is settled artificially. Reads the entrance gate information from the in-vehicle device of the ETC vehicle and the IC card by wireless communication with the device,
The toll is automatically settled based on the read entrance gate information. As a method of automatically adjusting the toll, there is a method of recording a prepaid amount on an IC card in advance and using the IC card in a prepaid card-like manner, and a method of using a user's deposit account etc. as an IC card ID number. And a method of using an IC card in a credit card manner.

[0010]

However, such a toll collection system has the following problems. For example, a toll road using the above-described wireless communication open system has a constant toll regardless of the mileage,
Mainly, the toll is paid in advance at the entrance gate, so that only one checkpoint is provided for the settlement of the toll.

[0011] For this reason, for example, in the case where the destination of the vehicle of the user is beyond the section under construction and is located further ahead even though the road section of the toll road cannot be passed due to the construction or the like for some reason. However, the user's vehicle will exit the toll road once before this section, pass through the general road, and then enter the toll road again, but at this time, the toll road will have a fixed toll regardless of the mileage Nevertheless, since the user's vehicle passes the check point of the entrance gate twice, the user has to pay twice the toll. Therefore, it was necessary to reconsider the method of collecting fees for open systems using wireless communication.
