开放式小区对城市道路交通的影响

Influence of Open Residential Communities on Urban Road Traffic

封闭小区逐步开放已成为城市道路布局的新理念,引起广泛的关注和讨论.基于道路通行能力与道路容量、车辆速度之间的关系,以上海某小区为研究对象,对小区开放前后道路通行能力的变化进行计算.研究表明,开放式小区能够优化路网结构,从而提高道路通行能力.

The opening of gated communities becoming a new concept for urban road layout has been widely discussed recently.Based on the relationships between traffic capacity with road capacity and vehicle speed,taking a community in Shanghai for example,the changes of traffic capacity before and after opening of gated community were calculated.The study shows that open residential community can optimize the network structure and enhance the traffic capacity.
