为了深入研究进出交通对路段通行能力的影响,在分析城市道路进出节点交通流构成和运行特征的基础上,基于交通流冲突分析原理,利用理论分析建模的方法,针对不同进出交通对主线交通流6种可能的干扰类型,提出相应的通行能力计算模型,并对相关因素对主流向通行能力影响的敏感性进行了分析。结果表明:进出交通会对路段通行能力产生一定影响,各股干扰车流的影响程度与主路车道数、主路交通量、主路交通转向比例、次路交通量等因素密切相关。
In order to deeply study the influence of traffic entering and leaving on the traffic capacity of road sections, based on the analysis of traffic flow composition and operating characteristics of traffic entering and leaving nodes of urban roads, based on the analysis principle of traffic flow conflict and using the method of theoretical analysis and modeling, Flow six kinds of possible interference types and put forward corresponding calculation models of capacity, and analyzed the sensitivity of relevant factors to the impact of mainstream on capacity. The results show that the traffic entering and exiting will exert some influence on the capacity of road sections. The impact of traffic jam on each stock is closely related to the number of lanes in the main road, the traffic volume in the main road, the traffic steering ratio of the main road and the traffic volume on the secondary road.
