Quantitatively Modeling of Beijing Work Trip Spatial Distribution
基于家庭访谈数据，分析了北京不同区域、全市及不同社会群体的工作出行空间分布，建立了出行分布模型，发现高收入居民出行距离更长且分布更分散。
Based on the home interview data,we analyzed the work trip spatial distribution of different zones,the whole Beijing city,and different social groups. As a result,we established the modeling function of Beijing work trip distribution. It is demonstrated that residents with higher income are more dispersed around their work place,with the trip distance increase,trip index decreases more slowly; on the contrary,residents with lower income are laid less dispersedly,with trip distance increase,commute distribution decreases faster. We quantitatively reached a conclusion that people with higher income in Beijing are less constrained by trip distance. Our research would lay a base for the establishment of Beijing LUTI,and would contribute to experiments of urban spatial policy and the realization of sustainable development.
