【摘要】 以改进的NaSch模型为基础,采用开放边界条件,分别对普通交通灯和智能交通灯控制下的十字交叉路口交通流进行模拟.结果表明,主干道车辆较多时,智能交通灯控制下的主干道车辆平均速度和流量都比普通交通灯控制下高,并可减少车辆的无谓等待时间.更多还原

【Abstract】 Using the improved NaSch traffic model,we simulate the traffic flow on the crossroad under open boundary condition.The simulations are controled by ordinary traffic light and intelligent traffic light respectively.The results show that the average speed and the traffic flux under control of the later are greater than that controled by the former.Moreover,the vehicles controled by intelligent traffic light can cut down the unnecessary waiting time.更多还原
