街区制条件下微循环公交网络设计

Study on bus microcirculation network design under the block system

在国内、外街区制微循环公交研究的基础上,引出街区制、交通微循环及微循环公交的概念。针对现有微循环公交无网络设计研究的问题,对微循环公交网络设计进行了研究,分析了微循环公交线路设计的原则和优化目标。以乘客时间需求为主约束,构建以企业成本最小为目标的微循环公交线路设计的数学模型,并用遗传算法对该模型进行求解。通过算例分析,验证了该模型及其方法的可行性和适用性,满足了企业和乘客2方面的需求。

The research process of microcirculation public transport is summarized under the block system at home and abroad. The concept of block system,traffic microcirculation and microcirculation public transport were proposed. A mathematical formulation of bus microcirculation network problem in case of enterprise costs and the time which the passengers require is presented. For sloving this problem, genetic algorithm for obtaining good solutions was developed. The principles and optimization objectives of microcirculation bus line design are analyzed. The passenger time requirement as the main constraint is considered. The mathematical model of the microcirculation bus line design with the minimum cost of the enterprise is constructed. The model is constructed by genetic algorithm. The feasibility and applicability of the model and the method are verified by case study, which can meet the needs of both enterprises and passengers.
