单中心大城市土地利用对居民出行方式的影响

为了全面了解大城市内部土地利用对居民出行行为的影响,以团块状单中心大城市为例研究了居民出行方式的相关特征。结果表明,团块状单中心城市内部土地利用密度和区位对居民出行方式有显著影响,步行和自行车出行比例由市中心向外围随着人口密度的减小而递减;助力车、摩托车、公交车、私家车出行比例则由市中心向外围随着人口密度的减小呈梯度式递增。土地混合利用程度对出行方式的选择影响不明显。土地利用对居民出行方式间的转移没有显著影响,居民出行方式间的转移局部与全局的特征相似。

Effect of Land-use on Resident Travel Mode in Compact Single Center City

In order to understand the land-use effect on travel behaviors in the big city,this paper,taking the compact single center city as an example,studies the characteristics of the resident travel modes.Analysis result shows that the land-use density and location have significant impact on travel mode in compact single center city.For example,the travel proportions of the walk and the bicycle are progressively-reduced with the population density decreasing from the city center to periphery,while the travel proportions of the electric-bicycle,the motorcycle,the bus and the car increase as the population density increasing from the city center to periphery.The effect of land-use on travel mode transfer is small.The characteristic of the resident travel mode transfer in a certain part is similar to that of the whole situation.
