ITS50激光交调系统，采用激光非接触式精准测量，通过测量区域机动车的车高、车速、车长、车身轮廓来对机动车进行自动模型比对精确分型（可按交通运输部Ⅰ、Ⅱ类车标准分型），同时按《交调设备相关技术要求、管理办法及外场检测操作实施细则》中规定的 I 级设备要求，将车头时间、车速、车长、9 类车型号由激光器直接以 RS-485 输出，以供中心计算车流量、地点车速、车头时距、跟车百分比、车头间距 、时间占有率等交通情况调查数据。

ITS50 laser Intermodulation system, using laser non-contact precision measurement, By measuring the vehicle height, speed, length, and body profile of the motor vehicle in the area, the motor vehicle is automatically modeled(according to the standard types I and II of the Ministry of Transport). At the same time, according to the requirements of Class I equipment stipulated in the "Technical Requirements for Intermodal Equipment, Management Measures, and Implementation Rules for Outfield Detection Operations," the front time, speed, length, and type 9 vehicles are directly exported by the laser to RS-485. The center is used to calculate traffic survey data such as traffic flow, location speed, time distance from the front of the car, percentage of the car, distance from the front of the car, and time share.
