城市交通协同下的城市更新项目实施时序控制体系

Implementation Sequence Control System for Urban Renewal Projects Under Urban TransportationCoordination

城市更新项目实施时序控制是稳步、有序、高质量推进城市更新的重要手段,与城市交通系统协调发展是制定城市更新项目实施计划的重要考虑因素。在分析城市更新项目实施时序的交通影响因素的基础上,构建城市交通协同下的城市更新项目实施时序控制体系。控制体系由目标层、标准层和指标层3个层次组成,以交通枢纽引领更新、城市轨道交通带动更新、更新保障城市交通用地、城市轨道交通可承载、道路交通可承载5个方面进行控制,包含11项指标。明确了各项指标的评价标准,并采用层次分析法确定各指标的权重系数。最后,以广州市为例进行应用实践,提出广州市城市交通协同下近期阶段和中远期阶段的城市更新项目实施计划,将综合得分为0.35分及以上的城市更新项目列为近期阶段推进项目。这些项目一部分位于铁路枢纽、城市轨道交通枢纽等周边,另一部分是“十四五”时期建设道路经过的项目,有利于为城市更新提供良好的交通支撑。

Effectively managing the implementation sequence of urban renewal projects is crucial for promoting urban renewal in a stable,organized,and high-quality manner.Coordinated development with the urban transportation system is a key factor to consider when developing implementation plans for these projects.This paper presents an analysis of transportation impact factors on the implementation sequence of urban renewal projects and proposes an implementation sequence control system for urban renewal projects under urban transportation coordination.The control system consists of three levels:the goal level,the standard level,and the indicator level.It covers 11 indicators with the focus on five aspects:guiding renewal by transportation hubs,driving renewal through urban rail transit,ensuring urban transportation land in renewal areas,carrying capacity of urban rail transit,and carrying road transportation capacity.The evaluation criteria are defined for each indicator,and the Analytic Hierarchy Process(AHP)is used to determine their weighting coefficients.Furthermore,the proposed system is applied in practice using Guangzhou as a case study.Implementation plans for urban renewal projects in Guangzhou are proposed with the shortterm and medium-to-long term phases under the urban renewal and transportation coordination.Projects with a comprehensive score of 0.35 or higher are identified as projects to be promoted in the near term.Some of these projects are located near railway hubs and urban rail transit hubs,while others involve roads constructed during the“14th Five-Year Plan”period,providing strong transportation support for urban renewal.
