摘　　要：由于城市建设的扩张,新城区道路接入城郊高速公路的需求日益增加,同一城市区域的高速公路存在多个互通的情况也越来越多。互通立交间的距离较近时,立交分合流区的交通会产生相互的干扰。研究针对多个互通立交的路段,通过交通流微观仿真,对多个互通立交区分、合流区主要断面的平均速度、延误以及交通冲突等交通运行特征进行分析。并通过不同的预测交通量,对远期多互通立交路段的交通运行与交通需求的适应性进行分析。Due to the expansion of urban construction,the demand for new urban roads to access suburban expressways is increasing,and there are more and more multi-interchange situations in the same urban area expressway.When the distance between the interchanges is short,the traffic in the interchange and junction area will cause mutual interference.The study analyzes the traffic flow characteristics of multiple intersecting interchange sections and the average speed,delays and traffic conflicts of the main sections of the intersecting interchange through traffic flow micro-simulations.Based on the different forecast traffic volume,the adaptability of traffic operation and traffic demand of long-term multi-interchange sections is analyzed.
