Research on the calculation of coverage rate of bus stop based on GIS

Urban public transportation has several advantages, including intensiveness, high-efficiency, energy-saving and environmental-friendliness. Giving development priority to public transportation is a necessary requirement in reducing traffic jams, transforming development mode of urban transportation and improving the life quality of people. And improving the coverage rate of bus stop is an important mean to prioritize public transportation development. The coverage rate of bus stop is an important index to evaluate the level of bus services. Under the consideration of deficiencies of calculating the coverage rate with traditional methods, including the great difficulty to acquire the information of bus stops, the low efficiency in deducting repeated area and the inaccuracy of calculation results, an idea of calculating the coverage rate of bus stop with GIS buffer tool and isochrones tool is put forward in this paper. In addition, case study is done in this paper to prove the powerful operability of the two tools, which provides good technical supports for urban public service.
