Abstract

A non-stop toll collection system has a plurality of road-side radio apparatuses having mutually different radio communication regions, which transmit identification signals responsive to the installation locations thereof, a vehicle-mounted apparatus, which receives an identification signal, records a communication log for each road-side radio apparatus, in response to the identification signal, and transmits the communication log, wherein each of the plurality of road-side radio apparatuses receives the communication log and wherein, in the case in which the communication log indicates that another road-side radio apparatus and the vehicle-mounted apparatus have already communicated, the vehicle-mounted apparatus is instructed to perform billing processing.

Claims

1. A non-stop toll collection system comprising:

a plurality of road-side radio apparatuses having mutually different radio communication regions, which transmit identification signals responsive installation locations thereof;

a vehicle-mounted apparatus, which receives an identification signal, records a communication log for each said road-side radio apparatus, in response to said identification signal, and transmits said communication log,

wherein each of said plurality of road-side radio apparatuses receives said communication log and wherein, in a case in which said communication log indicates that another road-side radio apparatus and said vehicle-mounted apparatus have already communicated, said vehicle-mounted apparatus is instructed to perform billing processing.

2. A non-stop toll collection system according to claim 1, wherein at a particular road-side radio apparatus of said plurality or road-side radio apparatuses, if said identification signal of said road-side radio apparatus with which said vehicle-mounted apparatus has already communicated as indicated by said communication log therefrom is an identification signal of a road-side radio apparatus to the rear of said current road-side radio apparatus in a direction of vehicle travel, instruction is given to said vehicle-mounted apparatus to perform billing processing.

3. A non-stop toll collection system according to claim 1, wherein each of said plurality of road-side radio apparatuses repeatedly transmits one frame of transmitted data, made up of a plurality of slots, control information with respect to said vehicle-mounted apparatus being added to a control signal in said one frame, identification signals responsive to each of said installation locations for said plurality of road-side radio apparatuses being added to said control information.

4. A non-stop toll collection system according to claim 1, wherein said plurality of road-side radio apparatuses are installed in a line along a direction of travel of said vehicle.

5. A non-stop toll collection method comprising;

a plurality of roadside radio apparatuses having mutually different radio communication regions sending identification signals responsive to installation locations thereof;

a vehicle-mounted apparatus receiving said identification signals and, in response to said identification signals, recording and transmitting a communication log for each of the road-side radio apparatuses; and

each of the plurality of road-side radio apparatuses receiving said communication log and, if said communication log indicates that another road-side radio apparatus and said vehicle-mounted apparatus have already communicated, instructing said vehicle-mounted apparatus to perform billing processing.

6. A non-stop toll collection system according to claim 5, whereby wherein each one of said plurality of road-side radio apparatuses, if said identification signal of a road-side radio apparatus with which said vehicle-mounted apparatus has already communicated as indicated by said communication log therefrom is an identification signal of a road-side radio apparatus to the rear of the current road-side radio apparatus in a direction of vehicle travel, giving an instruction to said vehicles-mounted apparatus to perform billing processing.

7. A non-stop toll collection system according to claim 5, wherein each of the plurality of road-side radio apparatuses repeatedly transmits one frame of transmitted data, made up a plurality of slots, control information with respect to the vehicle-mounted apparatus being added to the control signal in the one frame, identification signals responsive to each of the installation locations for the plurality of road-side radio apparatuses being added to this control information.

8. A storage medium having an executable program for a non-stop toll collection method according to claim.
