车道车流 meaning in English

lane flow

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
本课题设计的是一种悬挂式超声波车流多信息检测器，通过悬挂于路面上方的超声波探头向路面周期性地发射脉冲信号，利用地面回波来判断遮挡物地存在，可用于检测行驶中的机动车车速、车高、车长、大中小分型以及累计车流量、车队长度等信息，并可用于多个车道车流信息的同时检测，综合这些测量参数可获得车流量的必要数据，可为公路建设提供必要的基础依据。
