This study conceptually confirms and empirically tests the potential that the significance and magnitude of the compact land use–trip time relationship differ by the degree of compactness and trip time. Based on a quantile regression of about 25,000 commuters in Seoul, Korea, the empirical analysis suggests a significant level for each neighbourhood land use variable and a magnitude change within the level. Weekend trip and school densities are significant for shorter trip time commuters, population density is significant for longer trip time commuters, and pedestrian density is significant for all commuters. Wherever significant, the land use variables exert stronger effects as their values increase.

土地利用与出行时间非线性关系的分位数回归

本研究从概念上确认并实证检验了紧凑土地利用-出行时间关系的重要性和幅度因紧密程度和出行时间而不同的可能性。基于韩国首尔约 25,000 名通勤者的分位数回归，实证分析表明每个邻里土地利用变量都有一个显着水平，并且在该水平内有一个幅度变化。周末出行和学校密度对于出行时间较短的通勤者来说很重要，人口密度对于出行时间较长的通勤者来说很重要，而行人密度对于所有的通勤者来说都很重要。无论在何处显着，土地利用变量都会随着其值的增加而产生更强的影响。
