国家“七五”重点科技攻关项目——城市交通管制系统由南京电子工程研究所等单位研制成功。该系统由微机、路口机、动态地图板、磁翻转室外可变标志板等部分组成。它在各种恶劣气候和环境下都能控制道路上车辆行驶的概况,监视车速、车辆流量,从而实现城市交通管制,减少或避免事故,提高调度速度,
National “Seventh Five-Year” key scientific and technological projects - urban traffic control system developed by the Nanjing Institute of Electronic Engineering and other units. The system consists of computer, junction machine, dynamic map board, magnetic flip outdoor variable sign board and other components. It is in a variety of adverse weather and environment can control the profile of the vehicle on the road, monitoring the speed of vehicles, traffic flow in order to achieve urban traffic control, reduce or avoid accidents and improve scheduling speed,
