目前国内外城市交通线控系统软件多达10余种且在不同国家地区的运用得到了良好的效果,其信号协调控制模型主要分为最小延误法和最大绿波带法。基于延误最小和带宽最大两个优化目标,对当前典型的交通线控系统软件的技术特性进行总结和分类,并从用户友好性、优化模型、软件扩展功能3个方面对各种线控软件的优缺点进行比较。最后,依据当前国内的交通特征及应用现状,提出线控软件研发中需重点考虑的因素,对今后干线信号协调控制软件的研究提出改进建议。
At present, there are more than 10 kinds of softwares for urban traffic control system at home and abroad and their application in different countries and regions has achieved good results. The signal coordination control model is mainly divided into the minimum delay method and the maximum green band method. Based on the two objectives of minimum delay and maximum bandwidth, this paper summarizes and classifies the technical characteristics of the typical traffic control system software, and analyzes the technical characteristics of the various types of remote control software from three aspects: user friendliness, optimization model and software extension function The advantages and disadvantages are compared. Finally, according to the current domestic traffic characteristics and application status, this paper puts forward some key considerations in R & D of wire-controlled software, and puts forward suggestions for improving the research of coordination and control software for main-line signals in the future.
