Description

  The present invention relates to a traffic information providing apparatus that provides traffic information to a service target vehicle.

  VICS (Vehicle Information and Communication System: “VICS” is a registered trademark of the above-mentioned foundation) is widely known as a technology for providing road traffic information to drivers. This VICS tabulates traffic information including traffic congestion and link travel time on each route based on fixed point observation information consisting of the number of vehicles, vehicle speed, etc. collected from various roadside sensors (vehicle detectors, loop coils, etc.). The traffic information is provided to the driver by wide-area communication such as narrow-area communication using beacons or FM broadcasting.

  In such a system, fixed point observation information cannot be collected in a place where a roadside sensor is not installed, so that there is a drawback that the accuracy of traffic information is lowered.

  Therefore, on-board terminals that collect probe information such as position data and speed data are mounted on a large number of probe vehicles, and traffic information and the like are generated from the probe vehicles collected by these on-vehicle terminals, and various roadside sensors ( Traffic information such as traffic jam information is generated using VICS information obtained via a vehicle sensor, a loop coil, etc., and supplemental traffic information collected by an in-vehicle terminal mounted on the probe vehicle is added to this traffic information. In some cases, advanced traffic information is generated and transmitted from the VICS center to the vehicle via optical beacon, radio beacon, and FM multiplexed signal media (see, for example, Patent Document 1).
