Evaluation and Optimization Study on Public Transportation Network in Three Areas of Shangdi,Qinghe,Xisanqi in Haidian District of Beijing

首先通过对海淀区上地、清河、西三旗等3个地区的地面公交线网进行详细调查分析;然后从线网密度、线路重复系数、非直线系数、平均站间距、站点覆盖率等5个方面对处于城市边缘地区的这3个人口密度大、交通拥堵严重的典型地区进行地面公交线网评价;继而有针对性地提出现况地面公交线网的主要问题,并结合城市边缘新兴地区的特点,提出相应的优化对策和改善方案,给出较为可行的优化方案。

The article analyzes the detail investigation of the ground public transportation network in three areas of Shangdi,Qinghe,Xisanqi in Haidian District,evaluates the ground public transportation network in these three areas with the great population density and serious traffic congestion located at the fringe area of city from five aspects of line network density,line repeating coefficient,non-straight line coefficient,average station spacing and station covering rate,specially points out the main problems existing in the ground public transportation network,and according to the characteristics of new focal area at the fringe of city,puts forward the relative optimized countermeasures and improvement scheme,and proposes the more feasible optimized scheme.
