Abstract: With the deepening of the housing system reform in China, the real estate market has gradually assumed an initiative shape along with tremendous changes in the city's housing spatial structure. Based on filed investigation and spot checks, this paper tries to set up a database of housing in Beijing and produce a map of housing spatial distribution.Firstly, the paper studies the traffic passages and the trend of housing spatial distribution and expansion. The authors believe that there exist strong relations between traffic passages and housing spatial distribution and expansion. Areas along main traffic lines, exits and entrances of expressways and areas around subway and light rail stations always become the best locations for agglomeration and development of urban housing. Beijing's housing spreads along the city's main stem and assumes a shape of concentric circles.Secondly, by means of GIS and field study, we research the relationship between Beijing's housing spatial distribution and traffic passages and the influence of fast traffic passages on local residents' selection of housing location. We deem that the construction of traffic passages can improve the accessibility to the existed housing and propel the value increase of along-passage lands. Meanwhile, it can also widen people's selection of housing location, thereby providing a potential profit guarantee for the development and construction of new housing projects.Finally, using questionnaires we analyze the influence of traffic conditions on residents' selection of housing location. We hold the opinion that when selecting the housing location, urban residents often put more attention on the traffic conditions. As a result, those housing projects boasting traffic convenience are easy to sell with comparatively high prices. Therefore, traffic conditions must be taken into account in the development of a housing project which should be adapted to the construction of fast traffic passages and main roads.
