-
In principle, ultrasonic sensors are suspended over a road, which keep emitting pulse signals periodically to nearby and feed back waves to decide existence of any obstacles, thus to detect the speed, height, length, different sizes ( heavy, medium and small ) of moving vehicles and accumulative flow as well as length of motorcade. optionally, it can be applied to multitude driving lanes simultaneously for traffic data. by integrating and analyzing these measured data, the necessary figures concerning traffic flow may be obtained, which are fundamental basis guiding road buildings
本課題設計的是一種懸掛式超聲波車流多信息檢測器，通過懸掛于路面上方的超聲波探頭向路面周期性地發射脈沖信號，利用地面回波來判斷遮擋物地存在，可用於檢測行駛中的機動車車速、車高、車長、大中小分型以及累計車流量、車隊長度等信息，並可用於多個車道車流信息的同時檢測，綜合這些測量參數可獲得車流量的必要數據，可為公路建設提供必要的基礎依據。 -
