城际快速路客运站点设置方法

为方便城际快速路沿线居民出行,提出城际快速路客运站点设置方法.针对城际快速路客运线路的运营特点,提出一种寻求最少数量的居民点集对沿线居民点进行全覆盖的算法;以居民步行总距离最小为目标建立优化模型,确定每个居民点集所对应客运站点的最佳位置;为了提高客运线路的运行效率,引入灰色聚类方法,建立量化的聚类指标体系及标准,通过评估每个站点的重要度对站点的数量进行优化;最后以一条城际快速路为例对上述方法进行验证.结果表明:该方法是一种行之有效的站点设置方法,实现了站点位置和数量的双优化,能够满足城际快速路沿线主要居民出行需求和线路快速运行的需要,从而使得城际快速路上客运站点的布局更加合理.

Setting method of passenger site on inter-city expressway

To facilitate residents travel along inter-city expressway, the setting method of passenger sites on inter-city expressway was proposed. In accordance with the operating features of passenger lines on inter-city expressway, an algorithm was proposed to achieve full coverage for all settlements by seeking the minimum number of settlement sets. Optimization model was established with the target of minimizing total walking distance to determine the best place of each passenger site corresponding with settlement set. In order to improve the operational efficiency of passenger lines, grey clustering method was introduced and the quantitative clustering index system was established to optimize the number of sites by assessing the important degree of each site. Finally, the above method was validated by a case study. The results show that it is an effective approach for setting sites. The method achieves dual optimization for the location and the number of passenger site, meets the demand of the most residents along the intercity expressway, and makes site layout more reasonable on inter-city expressway.
