Abstract

A toll collection system obtains the data showing that the vehicle enters into the entrance of a toll road and data obtained from the on board unit mounted on the vehicle as the entrance passing data and the data showing that the vehicle exits from the exit of the toll road and the data peculiar to the on board unit mounted on the vehicle obtained by wireless communication with the on board unit as the exit passing data. Furthermore, the system specifies the utilization by the vehicle basing upon the obtained exit passing data and the entrance passing data and also, obtains the data read out from the number plate provided on the vehicle and specifies the vehicle basing upon the data read out from the number plate, when the utilization by the vehicle cannot be specified.

Claims

1. A Toll collection system comprising:

entrance data obtaining means for obtaining data showing that a vehicle has entered an entrance of a toll road and data obtained from an on board unit mounted on the vehicle by wireless communication as entrance passing data;

exit data obtaining means for obtaining data showing that the vehicle has exited from an exit of the toll road and data peculiar to the on board unit obtained by a wireless communication from the on board unit mounted on the vehicle as exit passing data;

first vehicle specifying means for specifying a utilization by the vehicle basing upon the obtained entrance passing data and the exit passing data;

toll calculating means for calculating toll charge basing upon the specified utilization by the vehicle that is specified by the first vehicle specifying means;

means for obtaining data readout from a number plate provided on the vehicle; and

second vehicle specifying means for specifying the vehicle basing upon the data obtained from the number plate when the utilization by the vehicle cannot be specified by the first vehicle specifying means.

2. A system as claimed in

claim 1

, wherein the second vehicle specifying means includes:

means for preparing abnormal cases details including a data peculiar to the on board unit that is obtained from one of the exit passing data and the entrance passing data and transmitting the abnormal cases details to the entrance data obtaining means when the vehicle cannot be specified basing upon the data obtained from the number plate.

3. A toll collection method comprising the steps of:

Further in accordance with the present invention there is provided a toll collection method comprising the steps of obtaining data showing that a vehicle has entered an entrance of a toll road and data obtained from an on board unit mounted on the vehicle by wireless communication as entrance passing data;

obtaining data showing that the vehicle has exited from an exit of the toll road and data peculiar to the on board unit obtained by wireless communication from the on board unit mounted on the vehicle as exit passing data;

specifying a vehicle basing upon the obtained entrance passing data and the exit passing data;

calculating toll charge basing upon the exit passing data and the entrance passing data;

obtaining data readout from a number plate provided on the vehicle; and

specifying the vehicle basing upon the data obtained from the number plate when the vehicle cannot be specified by the data peculiar to the on board unit included in the exit passing data and the entrance passing data obtaining data showing that a vehicle has entered an entrance of a toll road and data obtained from an on board unit mounted on the vehicle by wireless communication as entrance passing data;

obtaining data showing that the vehicle has exited from an exit of the toll road and data peculiar to the on board unit obtained by wireless communication from the on board unit mounted on the vehicle as exit passing data;

specifying a vehicle basing upon the obtained entrance passing data and the exit passing data;

calculating toll charge basing upon the exit passing data and the entrance passing data;

obtaining data readout from a number plate provided on the vehicle; and

specifying the vehicle basing upon the data obtained from the number plate when the vehicle cannot be specified by the data peculiar to the on board unit included in the exit passing data and the entrance passing data.

4. A method as claimed in

claim 3

further comprising the step of;

preparing abnormal cases details including a data peculiar to the on board unit that is obtained from one of the exit passing data and the entrance passing data and transmitting the abnormal cases details to the entrance of the toll road when the vehicle cannot be specified by the data readout from the number plate.

5. Toll collection system comprising:

entrance data obtaining means for obtaining data showing that a vehicle has entered an entrance of a toll road and data obtained from an on board unit mounted on the vehicle by wireless communication as entrance passing data;

means for imposing toll charge for a specified section on the vehicle basing upon the obtained entrance passing data;

exit data obtaining means for obtaining data that the vehicle has passed from an exit of the toll road and data obtained from the on board unit by wireless communication as exit passing data; and

settling means for specifying the vehicle basing upon the exit passing data and the entrance passing data obtained respectively and changing the imposed toll charge corresponding to the travelling distance and collecting the toll charge.

6. A system as claimed in

claim 5

, wherein the exit passing data includes data peculiar to the on board unit obtained by wireless communication with the on board unit.

7. A system as claimed in

claim 6

, wherein the exit data obtaining means includes:

means for obtaining data readout from a number plate provided on the vehicle; and

the settling means includes;

means for specifying the vehicle basing upon the data readout from the number plate, in case the vehicle could not be specified basing upon the data peculiar to the on board unit included in the exit passing data and the entrance passing data respectively.

8. A system as claimed in

claim 7

, wherein the vehicle specifying means includes:

means for preparing abnormal cases details including data peculiar to the on board unit that is obtained from one of the exit passing data and the entrance passing data and transmitting the abnormal cases details to the entrance of the toll road when the vehicle cannot be specified by the data readout from the number plate.

9. A toll collection method comprising the steps of:

obtaining data showing that a vehicle has entered an entrance of a toll road and data obtained from an on board unit mounted on the vehicle by wireless communication as entrance passing data;

imposing toll charge for a specified section on the vehicle basing upon the obtained entrance passing data;

obtaining data that the vehicle has passed from an exit of the toll road and data obtained from the on board unit by wireless communication as exit passing data; and

specifying the vehicle basing upon the exit passing data and the entrance passing data obtained respectively and changing the imposed toll charge corresponding to the travelling distance and collecting the toll charge.

10. A method as claimed in

claim 9

, wherein the exit passing data includes data peculiar to the on board unit obtained by wireless communication with the on boar unit.

11. A method as claimed in

claim 10

further comprising the steps of:

obtaining data readout from a number plate provided on the vehicle; and

specifying the vehicle basing upon the data obtained from the number plate when the vehicle cannot be specified by the data peculiar to the on board unit included in the exit passing data and the entrance passing data, respectively.

12. A method as claimed in

claim 11

further comprising the step of:

preparing abnormal cases details including data peculiar to the on board unit that is obtained from one of the exit passing data and the entrance passing data and transmitting the abnormal cases details to the entrance of the toll road when the vehicle cannot be specified by the data readout from the number plate.
