摘　　要：首先,给出单交叉路口的定义,从抽象模型mn网络出发,该文提出城市交通的动态多车道、四相位控制模型;提出阻塞判别条件,并给出阻塞时对路口控制的网络模型。将两种系统综合在一起,给出多目标优化的性能指标及其约束条件。采用遗传算法进行多目标优化,仿真结果表明该方案是可行的。First,giving the definition of isolated intersect io n,from the abstract model of mn traffic network system,this paper processes t he dynamic multi-driveway four -phase network model of urban traffic,raises t he term of jamming differentia,gives the network model of the intersection when jammed.Using the two system s together,the paper gives the multi-objective optimal property index with its constrains.Applying the genetic algorithms ,th e paper accomplishes the multi-objective optimization.The simulation results t estify the feasibility of the program.
