本文在分析主路为单车道情况的基础上,通过定义间隔余隙,建立了主要道路为双车道及多车道情况时,无信号交叉口支路车辆穿插通行能力的新的分析模式,并推出了其一般公式。公式考虑了各车道任意的临界间隔分布和任意的跟车时距分布,其一般性保证了各种主路交通特性和支路车辆的行为特性能在模型中得到真实反映,因而结果是符合实际的。本模式还适用于高速公路合流,信号交叉口车辆左转等问题的分析研究。 Based on the analysis of the main road as a single lane, a new analysis mode of interspersed traffic at the non-signalized intersections is established by defining the clearance gap when the main road is two-lane and multi-lane. The general formula. The formula takes into account the arbitrary critical interval distribution of each lane and any following-car-to-track distribution, which generally guarantees that the traffic characteristics of various main roads and the behavior of the tributary vehicles can be truly reflected in the model, so the result is in line with the real of. This model is also suitable for highway convergence, left-turn signal intersection and other issues analysis.
