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 enti…
