Abstract：AbSTRAcT The scientific diagnosis of urban mobility is a powerful method for the solutions to urban problems, especially traffic issues. Restrained by data sources and calculation condition, existing models of urban accessibility or mobility mostly focus on static or local area analysis with absence of quantized description of general mobility in city scale. Using internet data and algorithm program, a standard urban mobility model that covers accessibility calculation between al nodes in the city is created and another model is created on this basis, which takes the city centers, nearest commercial centers, nearest parks and external transportation facilities as the reference frame. This paper employs the latter model to conduct a diagnosis on the general mobility of Shanghai central city. Major structural characteristics are revealed, such as descending mobility from inside to outside, difference between east and west part and finger radiation structure etc., and nodes which need mobility promotion are located.
