Samenvatting
It is important to measure traveling time along each network link in order to optimize urban traffic signal control. A vision sensor was developed which is able to measure traveling time between the adjacent intersections, installing a single camera at each intersection. This vision sensor covers whole the area of an intersection, and detects a region of vehicle in an image and classifies vehicle sizes and colors. The two vehicle feature sequences are compared with Dynamic Programming Matching to search the same vehicle sequences. Measured traveling time has a margin of error of 4.5% one way or the other for true traveling time. For the covering abstract see ITRD E134653.
