摘要
为模拟区域路网的单向通行效果,运用随机分配模型的基本思想,提出一个交通仿真系统.选取福州市三坊七巷街区为研究对象,应用仿真手段对该路网分别进行单向和双向两个方案的模拟现状交通分配,比较各路段交通量和饱和度变化情况.通过对比可以看出,实施单向交通极大地提高了三坊七巷街区道路通行能力,是缓解交通压力的有力措施.
A traffic simulation system is developed by applying the basic idea of stochastic assignment model for the effect of one-way passage in regional road network. Taking Sanfangqixiang Street in Fuzhou as an example simulates the status traffic assignment of two programs that one-way traffic and two-way traffic, analyses the change of traffic flow and saturation in every road section. The compara- tive experiment showed that the application of one-way traffic increases traffic capacity greatly and the effective measure to relief the traffic pressure of congestion.
