Transit Accessibility and the Characteristics of Resident’s Travel Based on GIS

Based on the urban public transport network data of 2011 and supported by the GIS software, the transit accessibility in communities is analyzed in this paper. Meanwhile, based on the survey data, how well the supply of public transport matches the transportation demand of community residents is explored. The results show that: transit accessibility in four sample communities in Guangzhou all present the distribution characteristic that it diffuses incrementally along the bus and subway routes network from community to all around; transit accessibility during the morning and evening peak hours is worse than that in other hours; the supply of public transport can basically satisfy the residents’ public transport travel demand for work and leisure, but there are still some public transport unreachable areas beyond the maximal bearable commuting time; the supply of public transport can’t meet the transportation demand of community residents for shopping.
