基于多源多汇最大流模型评价小区开放

Evaluation of opening community based on the multi-source and multi-sink maximum flow model

建立了评价指标体系和关于车辆通行的数学模型,通过多源多汇最大流模型,定义最大交通流量增长率,给出了对应的路网通行能力改善效果评判标准,并将其应用于不同类型的小区,研究了开放封闭式小区对周边道路通行的影响,从而为城市规划和交通管理部门提出关于小区开放的合理化建议。

In this paper,the evaluation index system and the mathematical model of vehicular traffic are established. The maximal traffic flow growth rate are defined by the multi-source and multi-sink maximum flow model,as well as the corresponding evaluation criteria of the improvement of road network capacity is given,and which will be applied to different types of residential areas to study the impact of opening closed communities on the surrounding road traffic. Finally the rational recommendations of opening community will be put up with for the urban planning and traffic management department in this thesis.
