DEVELOPMENT OF A MEASUREMENT SYSTEM FOR VEHICLE MOVEMENT

Information collected via ultrasonic vehicle detector is limited to traffic volume and occupancy, due to its point sensing characteristic. A measurement system is developed for vehicle movement that allows for the collection of a variety of traffic information. Collected data from the system, with its ability to measure various vehicle behavior, will be better for current advanced traffic control strategies. Using a video camera, data on velocity, position, and other information can be collected, locating the vehicle within a section of maximum 100 m long. The measurement is conducted on a real-time basis, because image data acquired 15 times in a second are processed sequentially by parallel processing. In the vehicle detection algorithm, a combination of two methods is used; one is interframe differencing method and one is background frame differencing method. Because of the algorithm, obstacles are eliminated. Consequently, a high accuracy rate is obtained in detecting vehicles continuously during the day and night. This measurement system can be applied widely as a multi-purpose detector, which grasps the current behavior of vehicles. This paper describes some application examples, such as measurement of dilemma phenomenon or directional traffic volume in and around an intersection, and measurement of illegal parking vehicles.
