基于步行接驳效率的轨道交通站点改扩建方式与效果预测——以重庆轨道交通三号线观音桥站为例

Pedestrian Access Efficiency-based Renovation and Expansion Methods and Effect Precasting for Rail Transit Stations——A Case Study of Guanyinqiao Station of Line Three in Chonqing Rail Transit

由于轨道交通具有运量大、速度快、安全、准时、保护环境、节约能源和用地等特点,因此国内城市轨道交通的发展呈上升趋势。但同时也暴露了在设计初期对人流量预估不足等问题,导致轨道交通站体本身容量不足,人的通行时间增加,严重降低了使用者的步行接驳效率。因此,不少站体在建成后几年内不得不进行改扩建。该文以重庆市观音桥站为例,调研站点各个出入口的人流量现状,结合轨道交通影响域步行行为特征和空间类型,分析不同使用背景下的站体改扩建方式。最后运用行人仿真软件对其改扩建方案进行验证,并提出更有效解决方案[1]。

Thanks to the advantages of huge capacity, high speed, security, punctuality, environmental protection, conservation in energy and land use,urban rail transit in China is steadily on the rise. However, the pitfalls also emerge like inadequate estimation on passenger flow in early design period,causing insufficient station capacity, prolonged passing time and low pedestrian accessing efficiency. Therefore, many rail transit stations have to be renovated in just a few years. Based on the case of Guanyinqiao Rail Station in Chongqing, this paper studies the current passengers flow, and combined with the impacts of pedestrian domain behaviors and spatial types, analyzes the renovation and expansion methods for the stations under different using conditions. In the end, the pedestrian simulation software is adopted to verify the renovation and expansion solution, with a more effective one presented.
