关于小区开放对道路通行影响的研究
The Research on the Influence of Community Opening on Road Capacity
摘要: 小区的开放必然会引起之前的交通系统和城市结构的改变。本文通过建立适当的数学模型对小区开放后对周边道路通行所产生的影响进行了分析。本文利用全有全无的分配方法结合Matlab程序解决了车辆在小区开放后的分流问题,接着利用所得出的流量,计算车辆在行驶完某段路所需的时间,以此来建立模型。通过计算车辆行走相同路程的时间的多少来衡量小区周围道路的交通流畅程度,从而确定小区开放后的影响。最后,我们运用已建立的模型,进行定量的分析,分别得到了开放前后,车辆绕行小区一周的时间,得出了小区开放会对周围交通产生积极影响的结论。
Abstract:
The opening of the community will inevitably lead to changes in the traffic system and urban structure. In this paper, the influence of the community opening on the surrounding road is analyzed by setting up an appropriate mathematical model. In this paper, we solved the problem of vehicle shunting after the opening of community through the “all or nothing” allocation method and the Matlab program. Then we used the result of flow to calculate the time of vehicle finishing a certain road. In this way, we built the mathematical model. By calculating the time of vehicles travels on the same distance we can know the traffic condition around community, so as to know the impact of opening of the community. Thirdly, we used the established model for quantitative analysis and obtained the time of the vehicle detour around the community, before and after the opening. Finally, we obtained the conclusion that the opening of the community has a positive impact on the surrounding road capacity.
