基于组态王的交通信号配时控制教学实验平台

摘要

针对公安院校交通管理工程专业学生的培养目标和未来交警职业的工作性质和要求,以组态王为开发软件,设计了一个交通信号配时控制的教学实验平台.该平台以一个十字交叉口为载体,可以模拟实际路况进行交通信号灯的配时设计实验.平台核心算法采用经典的Webster方法,根据路口的交通流量、饱和流量等参数可以进行周期和相位绿灯设置,并基于饱和度和通行能力进行配时效果比较.相比于商业仿真软件,平台具有目标用户针对性强,实验内容符合交警部门需求,实验操作在保留专业性的同时具有操作简单易学易用等特点.%According to the training target of students majoring in traffic management engineering in police colleges and the professional requirement of the future traffic police,a teaching experiment platform for traffic signal timing is developed using King-View software.An intersection simulating practical road situation is designed to carry out experiments of traffic signal timing.Webster method is adopted as the core algorithm in this platform.Cycle and phase green light can be set based on the values of the traffic flow and saturation flow,while the simulated effect can be tested according to the saturation degree and traffic capacity.Compared with the commercial simulation software,this platform has the characteristics of meeting the real demands of traffic management departments,and it is easy to use,while keeping the professional ability.
