| Abstract: | GPS (Global Positioning System) is the most popular satellite positioning technology in the world at present, but its applications in the city traffic are confined to the positioning and navigating vehicles. This paper presents a new detection method of traffic conditions on the basis of GPS technology. By virtue of the instantaneous velocity of vehicles and precise time information supplied by GPS, a mathematic model can be established. Then, a series of important traffic condition information can be obtained, such as traffic volume, mean velocity, driving time, driveway occupancy, etc. This technology realizes the real time detection of city traffic condition and offers the premise for intelligentizing of city traffic management system. |
