本文从影响道路通行能力的因素入手,分析小区政策开放的原理以及可能造成的影响,进而选取饱和度、行车时间、最大密度作为评价指标,建立综合评价指标体系对开放小区效果进行了定量化分析。然后建立开放小区条件下车辆通行模型,依据容量限制交通分配方法给出三项评价指标的计算程序,并对其中的一些关键参数给定了确定方法。最后针对城市不同区域给出了开放建议。
This article starts from the factors that affect the capacity of the road, analyzes the principle of the open policy of the community and the possible impact, and then chooses the saturation, the travel time and the maximum density as the evaluation indexes and establishes the comprehensive evaluation index system to quantitatively analyze the effect of the open community . Then, the vehicle traffic model under the condition of open residential area is established, and the calculation procedure of three evaluation indexes is given according to the capacity limited traffic allocation method. Some of the key parameters are given. Finally, it gives suggestions for opening up to different regions of the city.
