Description

System and method for providing traffic information

The present invention relates to a traffic information providing system and method.

In the conventional method of collecting and transmitting traffic information, a beacon is installed on a road to convert a distance and time of a vehicle passing through a specific point into information, and then transmit the information to a traffic information collection server and reprocessing the traffic information collection server. Traffic information on roads is provided to users, government offices, and companies. This method is expensive to install beacons to be installed for each road section and maintenance to maintain beacons directly on the road. In order to improve this, while using the Probe-Car equipped with GPS, while driving on the road, the individual GPS position and speed of the vehicle are transmitted to the traffic information collection server, and the road is reprocessed by the traffic information collection server. Traffic information on the service to users, government offices, companies, etc. The systems utilizing this include ROTIS and MBC's DARC.

However, in the case of the beacon method, the sensor installation cost is high for each section of the road, and the maintenance cost to go to the road and perform maintenance is not easy. Also, even when using a probe-car using GPS, the conventional method collects individual vehicle positions, transmits them to the traffic information collection server at a set time interval, and reprocesses the information gathered at the traffic information collection server. The total time required to go through the process is about 10 to 20 minutes, which cannot provide real-time traffic information. Also, unnecessary communication load due to excessive data amount due to sending the location and speed of individual vehicles through the wireless network. This leads to unnecessary communication costs.

Such a conventional traffic information collection method is simply based on the speed information of the vehicle, there is a problem that the generated traffic information may be inaccurate.

Background Art of the Invention There is a patent document relating to an apparatus and method for controlling an idle stop of a vehicle, and discloses not only waiting for traffic signals but also performing idle stop control for the vehicle even when the vehicle stops for a predetermined time. .
