| In recent years, with the steady development of social and economic in China,and resident’s living standards improved, under the circumstance of state macro control on the housing market, there has been an unprecedented increase in residents’travel demands. The development of affordable and commodity housing guarantee the people’ s residency, and at the same time it causes trouble in residents’daily transit, especially for the low-income residents. It brings great challenge for their daily travel behavior by public transit. Poor accessibility of public transport, low bus service standards, single lines and many other issues like these are becoming increasingly prominent in affordable housing areas. Based on this background, it is necessary to find out the different effects of public transit on residents who lives in affordable and commodity housing, and analysis reasons that cause the differences. So that we can provide theoretical basis in order to enhance and improve the overall infrastructure, such as transport facilities, public service facilities, to meet residents’travel demand. And ultimately achieve the goal that optimize the city traffic network structure, allocate the city traffic resources rational, and meet the residents daily travel needs to the maximum extent.Based on this, this study takes affordable and commodity housing as research objects. It firstly introduced the current transit network characteristics and transit accessibility characteristics of Xi’an. Then we analysis the relationship between affordable housings and transit accessibility so as to select the sample points. In order to make a control group, we choose commodity points that have the similar conditions by the same amount. In addition, based on the questionnaire survey data, this study explored the travel behavior of residents who live in the different type of house and analysis the difference of their travel behavior. Finally, by constructing MNL model and multivariable linear regression model, this study explored that to what extent transit accessibility affect residents’travel behavior and what the difference between residents from living in the two different types of houses are. The main conclusions are as follows.(1) The findings indicate that the spatial characteristic of accessibility is "circling structure". The farther the distance away from the center city, the worse the accessibility is. The affordable housings are mainly located in the areas that are in a lower level of transit accessibility, and usually these areas are far away from the downtown area.(2) Both commuting and non-work travel, residents living in affordable and commodity housings exist significant differences in the travel mode, travel time, travel distance, travel strength. Residents living in public rental housing mainly rely on public transport and walking, and residents living in economically affordable housing use public transport and walking at the same time, they also use cars. Residents living in commodity housing use car more often. Residents living in public rental housing showed obvious weaknesses in travel time and travel distance, they have a longer trip time and trip distance.(3) Transit accessibility shows no influence on commuting travel modes of residents living in both affordable and commodity housing. It significantly affects the non-work travel modes, but residents living in different housings have the diversity degrees. The degrees decreased from affordable housing to commodity housing. Transit accessibility significantly affects the travel strength, and there exists a big difference between residents living in different types of housings.(4) Residents living in affordable housing rely mostly on public transport, but residents from commodity housing do not show obvious dependence on public transport. |
