The comprehensive transportation system planning of prefecture-level cities has important guiding significance for urban development, which is necessary to fully consider the transportation location characteristics of prefecture-level cities within the province or urban agglomeration, to propose planning strategies in coordination with regional positioning and existent development level, supporting the planning and construction of important transportation infrastructures. Based on geographic information data, this paper establishes an evaluation model of transportation location and accessibility considering highway network density, connection rapidity with regional hub cities and accessibility to transportation hubs including railway, waterway and aviation. Taking Jiangmen City as an example, this paper comprehensively analyses its regional transportation advantage within the scope of Guangdong Province based on the actual geographic information data in 2013 and the planning data for the future, in order to evaluate the effect of transportation planning. The results show that this method can effectively identify the relative level of accessibility and transportation location characteristics of a city among all prefecture-level cities in the province or urban agglomeration, which can provide support for comprehensive transportation system planning.
