US 7,010,583 B1 · Transport system

Abstract

A transport system composed of road side stations installed along roads and vehicles running on roads, wherein emergency processing at the time of an accident, a local information providing service, and so on are realized by the road side stations in cooperation of the road side stations and the respective vehicles. In the transport system, a plurality of road side stations are interconnected through a road side communication network, and a plurality of vehicles communicate with the road side stations. A vehicle transmits a request message containing a service code and location information. A road side station receiving the request message broadcasts the request message to the network. The road side stations receive the message, and determine whether or not requested processing should be executed based on the service code and the location information. When determining that the processing should be executed, the road side station executes processing indicated by the service code.

Dependent claims

An information processing method in a transport system having a plurality of roadside stations disposed along a road and interconnected through a network along the road, said roadside stations each including a radio communication unit for communicating with a mobile body, the method comprising the steps of:

said mobile body transmitting request information to at least one of said plurality of roadside stations, said request information including contents information indicative of contents of a request for a processing for the mobile body, and location information indicative of a location at which said mobile body exists;
a roadside station, which has received said request information, transmitting said request information to other roadside stations through said network;
and
each of said plurality of roadside stations, which have received said request information, determining to execute a processing for the mobile body based on said location information when a distance between the mobile body and said roadside station along the road falls into a predetermined value, and broadcasting a result of said execution of said processing to said mobile body or to other roadside stations interconnected through the network.

A transport system having a plurality of roadside stations disposed along roads with relay devices and interconnected through a network along the roads with the relay devices, said roadside stations each including a radio communication unit for communicating with a mobile body, wherein:

each of said roadside stations comprises:
means for directly receiving from the mobile body location information indicative of a location at which the mobile body exists, and route information indicative of a route along which the mobile body is running by using the radio communication unit;
means for broadcasting the location information and the route information to other roadside stations interconnected through the network;
means for determining to execute a processing for the mobile body based on said location information when a distance between the mobile body and said roadside station along the roads reaches a predetermined value;
and
means for executing said processing for the mobile body based on the determination by said means for determining.
