小区开放对道路通行能力影响的数学模型

The Mathematical Model of the Influence of Community Opening on Road Capacity

本文运用了交通运输网络脆弱性评价模型、BA无标度网络模型和等效通行模型等对小区开放后对周边道路的影响进行了探讨。首先分别考虑外部、内部影响因素对周围道路通行的影响,得出小区内部结构越复杂,开放程度越大,所处位置较偏远的小区类型周边道路通行能力越好。然后在得到的最优内部影响指标下,获得了最佳小区结构下小区开放后将提高道路通行能力。

In this paper, we discuss the impact of the traffic network vulnerability evaluation model, BA scale-free network model and equivalent traffic model on the surrounding roads after the opening of the community. We first consider the external and internal influencing factors on the surrounding traffic, and show the result that the village type road traffic capacity is better if the inner structure of the community is the more complex and more open, also the location is more remote. And then, under the optimal internal influence index, we obtain that the road capacity is improved after the community is opened.
