随着开放小区的政策出台后,对不同小区开放后能否起到缓解交通压力的作用的置疑声不断上升,为此选取了3种典型代表类型的小区作为研究对象;通过在研究BPR函数的基础上建立Braess悖论模型进行分析研究,最终结果显示并非所有类型的小区在开放后都能够缓解周边道路的交通压力。 With the introduction of the policy of open community, the suspicion of whether different communities can play a role in alleviating traffic pressure after the opening up of the community continues to rise. Therefore, three typical representative types of community are selected as the research object. By studying the BPR function Based on the establishment of Braess paradox model for analysis and study, the final results show that not all types of communities are open after being able to ease the traffic pressure on the surrounding roads.
