交通事故、交通堵塞等问题日益严重,不但给社会造成了大量的经济损失,而且也带来了很多社会问题。本文采用智能交通系统来充分发挥现有交通基础设施的潜力,提高快速路的运输效率,缓解交通拥挤。文中介绍了智能交通控制器上位机的设计思路和实现方法,并对其调试和运行结果做了介绍。实践证明该上位机系统能够完成对控制器的各种控制和信息采集与信息显示,具有很好的交互界面和可靠性。 Traffic accidents, traffic jams and other issues are becoming more and more serious. It not only causes a lot of economic losses to the community, but also brings about many social problems. This article uses intelligent transportation system to give full play to the potential of the existing transport infrastructure to improve the transport efficiency of expressways and ease traffic congestion. This paper introduces the design idea and realization method of intelligent traffic controller PC, and introduces the debugging and running results. Practice has proved that the host computer system to complete a variety of controller control and information collection and information display, has a good interface and reliability.
