超音波感知器データを利用した旅行時間計測への遺伝的アルゴリズムの応用

抄録

The Information on travel time is useful to improve traffic efficiency, e.g., to reduce traffic congestion effectively. Travel time is computed from the passage time of vehicles observed at both origin (upstream) and destination (downstream) points. To do so, we are studying a vehicle identification method using vehicle height data obtained from ultrasonic vehicle detectors. However, matching method using vehicle height only, suffer from poor identification accuracy because many similar vehicles exist on the road. Therefore, we propose a method based on matching vehicle sequences (two or more vehicles). In addition, we develop this method using Genetic Algorithm based on traffic characteristic.
