Method and apparatus for collecting traffic information

Abstract

A method for collecting traffic information is described. The method includes a position information transmitting step of installing a position transmitting device at a starting point and an ending point of a link of entire road and transmitting position information of the link to probe vehicles. There is an information receiving/classifying/searching step of receiving a transmission signal of a corresponding position while traveling on a road, and continuously classifying and searching the intensity of the signal and the position information of the link. The method also includes a travel information transmitting step of detecting the position of the probe vehicles and the starting point and the ending point of the link according to the result of searching, computing a time, a distance and a speed required for traveling the link on the basis of the detected information, and transmitting the same. A traffic information managing step of receiving and systematically storing the travel information of the probe vehicles is included and a step of computing a representative value for the travel information of each link, and recognizing and managing the traffic flow information on the entire road processes the information. An apparatus is provided to perform the method.
