基于出行需求期望的城市快速路网均衡性研究

Research on Urban Expressway Network Equilibrium Based on Travel Demand Expectation

为评价大城市快速路路网均衡性,以上海市为研究案例,利用手机信令数据和百度API路径推荐,获取小区间出行需求期望,再基于小区间的出行需求期望从快速路网与地面路网的协调性、快速路网内部服务分担协调性以及各小区间快速路出行的可获得性三个视角对快速路网的均衡性进行分析,三个视角分别选取快速路出行绕行距离、快速路路网各路段的服务强度以及区域公平性作为度量指标,据此建立了大城市快速路路网均衡性的评价体系。

To evaluate the equilibrium of urban expressway network system.Taking Shanghai as a case study,the mobile signaling data and Baidu API route recommendation are used to obtain the inter-cell travel demand expectations.Then,the equilibrium of Expressway network was analyzed from three perspectives,travel demand expectations,the coordination between expressway network and surface road network,the service sharing and coordination within expressway network.The three perspectives use the detour distance of expressway travel,the service intensity of expressway network sections and regional fairness as measurement indicators respectively.Finally,an evaluation system is established for the equilibrium of urban expressway network system.
