多层次公交线网优化思路与方法——以常州市新北区为例

Optimization Concept and Method of Multilevel Public Transit Line Network

城市常规公交线网优化是城市公共交通逐渐完善的重要手段,以常州市新北区为例,探索了多层次公交线网优化思路与方法。剖析了常州市新北区常规公交线网存在的问题及问题形成的原因,针对问题提出了构建由快线、主线、微循环线路和特殊线路构成的多层次线网优化方法。具体包含线网优化的目标、思路和方法,通过评价,经过优化后的线路在线网密度、片区通达性、线网结构、非直线系数、乘客平均出行时间、线网效率等多方面得到了极大的改善。对于同类地区具有一定的示范意义。

The optimization of conventional urban public transit line network is the important method of gradually perfecting urban public transit. Taking Xinbei District of Changzhou City as an example, the article discusses the optimization concept and method of multilevel public transit line network, and analyzes the problems existing in the conventional public transit line network in Xinbei District of Changzhou City and the problem causes. Aiming at the problems, the article puts forward the multilevel line network optimization method composed of the express line, main line, microcirculation line and special line, which includes the objective, concept and method of line network optimization. According to the evaluation, the optimized line is greatly improved in many aspects of line network density, areal accessibility, line network structure,nonlinear coefficient, average travel time of passenger and line network efficiency, which has a certain demonstrating significance for the similar regions.
