基于宜居性的城市轨道交通布局规划优化研究

为提升城市轨道交通附近居民居住舒适度,提出基于宜居性的城市轨道交通布局规划优化研究。在宜居性理论背景下,建立城市轨道交通布局指标,确定布局规模,在交通站点数量相同的规划方案中获取最优规划方案。利用综合评价法分析城市轨迹交通布局规划方案,计算交通线路客流覆盖量,构建城市轨道交通布局规划模型。实验结果表明,基于宜居性的城市轨道交通布局规划优化方法不仅可以提高城市轨道交通布局的利用率,还可以降低城市轨道交通布局重复率,从而提高城市轨道交通布局的整体规划效果。

Optimization of Urban Rail Transit Layout Planning Based on Livability

This paper puts forwards a study on the optimization of urban rail transit layout planning based on livability for improving the living comfort of residents near urban rail transit.First of all,based on the theory of livability,the urban rail transit layout index was established and the layout scale was determined.Secondly,the optimal planning scheme was obtained from the planning schemes with the same number of traffic stations.Then,the urban rail transit layout-planning scheme was analyzed via the comprehensive evaluation method,and the passenger flow coverage of transportation lines was calculated.Finally,the urban rail transit layout-planning model was constructed.The results show that the method not only improve the utilization rate of urban rail transit layout,but also reduce the repetition rate of urban rail transit layout,thus the overall planning effect of urban rail transit layout can be improved.
