北京居住型轨道交通站点周边步行空间量化研究

Firstly, the key factors affecting the convenience and comfort of walking around Beijing residential rail transit stations were confirmed through questionnaire, the most significant factors respectively are the degree of walking detours and the street ground-floor commercial facilities, then quantitative researches were carried out on the two factors. 13 residential stations in Beijing were selected, and the coefficients of detours both under current situation and the scenario of open communities were calculated, moreover, the current situation was compared with other domestic and foreign cities. The distribution of street ground-floor commercial facilities around 13 stations was investigated, and the Huilongguan station was analyzed in details. The result shows that the degree of walking detours around residential stations in Beijing was relatively serious, and significant factors are, for instance, closed communities and road network. There are relatively continuous underlying commercial facilities over half of the sites, and the facilities around a few of stations were insufficient, the density of street ground-floor commercial facilities within 500 meters of Huilongguan station was 2.42 per 100 meters, which is far less than the walkable standard.
