Dynamic Simulation and Implementation of Mixed Traffic Flow at Urban Road Intersection Based on Multi-Agent

通过分析机动车和自行车在城市道路平交口处的动态行为特性,建立了平交口混合交通流微观行为模型,提出了基于Multi-Agent的平交口混合交通流动态并行模拟算法,构造了机动车和自行车的Agent类函数,通过计算机仿真再现了平交口混合交通流的动态行为特性。实测数据和仿真分析结果验证了所建模型是正确的。该研究成果解决了传统仿真技术不能协同模拟多种混合交通流动态行为特性的难题,同时为解决我国城市道路平交口的交通干扰和拥堵问题提供了一种新的模拟分析方法。

By analyzing the dynamic behavioral characteristics of motor vehicles and bicycles at urban road intersection,the micro-behavior models of mixed traffic flow at intersection were established,the dynamic parallel simulation algorithm for mixed traffic at intersection based on Multi-Agent system was presented,the Agent class functions for motor vehicles and bicycles were constructed,and the dynamic behavioral characteristics of mixed traffic flow at intersection were reproduced by computer simulation.These models were validated separately with field data and simulation results.The research results have solved the problem that dynamic behavioral characteristics of mixed traffic flow cannot be simulated by traditional simulation methods.At the same time,the research results provide a new simulation method to solve the traffic interference and congestion at road intersection in Chinese cities.
