Abstract

降雪や路面凍結によるスリップ事故は絶えることがない.これを防ぐために冬タイヤ規制が各路面で展開されているが,人員による目視判断によって行われているため,作業員の肉体的負担に伴う誤判定,車両の一時停車による渋滞等が発生している.そこで,我々は車両走行時にタイヤ/路面の接触に伴って発生する路面振動を収集し,周波数解析などから夏/冬タイヤの判別を行った.この結果,両タイヤの識別が可能という指針を得た.

According to traffic regulations, road administrators allow the use of winter tires in order to secure safe traffic flow during heavy snow days. In this situation, they must visually inspect vehicles to ensure summer tires are not being used on the expressways. Otherwise, heavy traffic jams come about inevitably. To avoid such traffic jams, an automatic tire discrimination system is required. In this report, simple signal parameters are proposed that descriminates between summer and winter tires using road surface vibration caused by running vehicles.
