我国智能交通信号控制系统应用现状分析及展望

Application Status and Expectation of Intelligent Traffic Signal Control System in China

随着经济持续高速发展,本世纪初开始,我国城市化、机动化进程明显加快。由于交通基础设施的新建、改善速度始终无法跟上日益增长的机动化交通需求,各大中城市先后出现了不同程度的交通拥堵问题,且大有向中小城市蔓延之势。而作为最易发生交通拥堵的道路平面交叉口,交通信号控制是否科学合理,直接关系到整个区域交通流的畅通有序。基于此,本文从道路交通信号控制系统规划和使用者角度,对我国智能交通信号控制系统建设、应用现状及存在问题进行了剖析,并对智能交通系统的发展趋势进行了展望。

With the rapid development of economy, the process of urbanization and motorization in China has speeded upsince the beginning of this century.As the traffic infrastructure construction and improvement speed cannot keep up withthe increasing of motorized traffic demand, large and medium-sized cities have emerged in varying degrees of trafficcongestion, and there is a tendency to spread to small and medium-sized cities. The intersection is the most vulnerableplace for traffic congestion.Whether the traffic signal control is scientific and reasonable is directly related to the smoothand orderly traffic flow in the whole area. Based on this, this paper analyzes the construction, application and existingproblems of intelligent traffic signal control system in China from the perspective of road traffic signal control systemplanning and users. Finally, the development trend of intelligent transportation system is prospected.
