城市公交换乘模型的优化研究

传统的城市公交网络换乘模型中,一般根据公交站点间距离确定公交站点间是否应设定换乘关系,但该方法比较主观,可能导致某些公交站点间必要的换乘关系缺失。本文在以常用的以标准距离建立的公交换乘关系基础上,提出在介于标准距离和扩展距离的站点之间基于最优线路分析决定是否添加换乘关系的方法,同时给出了具体的实施步骤和实例分析。结果表明本文提出的方法能够为用户提供更好的出行选择,从而更好地满足乘客的实际需求。

Research on Optimization of City Public Transit Model

In conventional city public transit model, transit relations are generally determined by straight distance between stations. However, above mentioned method is subjective as it may result in missing of some important transit relations. On the basis of public transit model using standard transit distance, this paper concerns with adding appropriate transit relations between stations having distance in the interval of standard distance and extended distance, and further provides a public station transit model based on route analysis. Meanwhile the paper gives specific construction process and case study. The result shows this new method will provide best travel solutions to passengers and fulfill their actual demands.
