Abstract

The Global Positioning System (GPS) is the most popular satellite positioning system in the world at present. From the development of GPS and current traffic condition monitoring methods, the paper presents a new detection method of traffic condition based on the GPS technology. It can derive conveniently the driving time, demand velocity of vehicles and driveway occupancy, and obtain the distribution function of velocity by means of fitting velocity values of short time periods, and the time mean of velocity by quadrature. The traffic volume is calculated by an interval mean of velocity, realizing a real-time detection of the traffic condition. This has important signification to city traffic induction and control, offering a necessary condition for the realization of an intelligent transportation system.
