Coupling Coordination Measurement between Information Attention and Service Level of Urban Public Transport

Abstract

The concept of urban public transport information attention was defined to determine travel information demand and spatiotemporal differentiation of urban public transport. On the basis of the Baidu index of urban public transport attention in 31 cities in China from 2011 to 2014, this study applied the standard deviation and the Theil index to analyze absolute and relative differences in urban public transport information attention. Then, the coupling coordination degree model was established to measure the coordination of information attention and service level of urban public transport. Results showed that the relative difference gradually diverged, whereas the absolute difference increased from 2011 to 2014. The regional rank changes of urban public transport information attention gradually diminished from east to west, the spatial coupling coordination between information attention and service level of urban public transport was low, and the differences between regions were significant.
