Abstract
A fixed station and an on-board apparatus are constructed to carry out a short range communication. The on-board apparatus specifies an application from a command included in reception data received from the fixed station and starts a corresponding processing, when an acquired command is a menu selection command. A menu including commodities and charges are displayed. When a selected item is determined, the determined content is displayed. When an IC card unit receives an IC card for settling the charge, the charge is settled by rewriting the IC card by data exchange via wireless communication. A short range wireless unit is used to ensure individuality of the communication. This short range communication may also be used at a vehicle repair shop, at a curved corner on a travel path or the like.

3. The communication method of claim 1 further comprising the step of:
-
carrying out wireless communication between the on-board apparatus and a fixed station having a limited communication area when the on-board apparatus is present in the communication area, wherein the on-board apparatus is mounted on the vehicle, wherein the fixed station is installed in a vicinity of a curved corner having a poor visibility and transmits the information on the running path and the information on the running vehicle to another vehicle approaching the object area which covers a predetermined range forward and rearward from the curved corner, and wherein the on-board apparatus controls a brake apparatus of the vehicle to avoid an emergency at the curved corner based on the information on the running path and information on the running vehicle.
