With the acceleration of urbanization and motorization in China,traffi c congestion has becomethe“bottleneck”in the development of major cities in China.If the urban traffi c problem can not be solvedeffectively,it will seriously affect the sustainable development of big cities.However,to solve the traffi cproblems in big cities,it is necessary to have a forward-looking view,and to determine the developmentstrategy of transportation in big cities according to China’s national conditions and the characteristics ofmajor cities.China’s urban land resources are limited,and the land available for road traffi c is increasinglyscarce,and the contradiction between supply and demand of transportation is intensifi ed.Urban populationis gathering in big cities and megacities,and the demand for urban transportation will increase at a fasterspeed.Based on GIS spatial analysis technology,the accessibility of public transport for residents in themain urban area of Nanchang City before and after the metro opening is measured,and improvementbenefi ts of accessibility of metro in different spatial patterns are analyzed.This paper puts forward theimprovement measures of metro to Nanchang traffi c as the suggestions of Nanchang traffi c management.
