既有城区“通学型”潮汐式拥堵机理与规划调控缓解模式

随着既有城区建筑、人口的高密度发展及私家车拥有量的快速提升，城市交通拥堵，尤其是潮汐式拥堵问题日益严重。目前已有不少学者从道路交通角度，土地利用与交通关系等方面进行研究，并取得一定进展。但是“通学”引起的潮汐式交通拥堵问题并没有被有效解决。本项目拟针对“通学型”潮汐式拥堵问题，运用城乡规划学原理，采用GIS服务区分析、网络分析法，探索“通学型”潮汐式拥堵的致堵机理，构建中小学周边交通网络模型，研究中小学规划布局策略与停车配建标准，拟提出一套“自走式”停车模式、及规划设计原则和方法。项目对揭示潮汐式拥堵机理，缓解既有城区潮汐式拥堵，提升既有城区宜居水平等方面具有理论意义和应用价值。

With the high-density development of buildings and population in existing urban areas and the rapid increase of private car ownership, urban traffic congestion, especially tidal congestion, is becoming increasingly serious. At present, many scholars have studied from the perspective of road traffic, the relationship between land use and traffic, and have made certain progress. However, the tidal traffic congestion caused by " commute to school" has not been effectively solved. This project aims at the problem of " commute to school " tidal congestion, the principles of urban and rural planning, GIS service area analysis and network analysis methods are used to explore the mechanism of " commute to school " tidal congestion, to build a traffic network model around primary and secondary schools, to study the planning and layout strategies and parking allocation standards of primary and secondary school, meanwhile，a set of "self-propelled" parking mode is proposed, as well as principles and methods of planning and design. The project has theoretical significance and application value in revealing the tidal congestion mechanism, alleviating the tidal congestion in the existing urban area, and improving the livable level of the existing urban area.
