Abstract:  Commuting is a periodical and stable travel behavior of urban residents, which is an important research content of urban development planning and public transportation management. Taxi GPS trajectory data reflects urban traffic conditions and citizens’ travel patterns to a certain extent. Aiming at the problem of taxi regional commuting pattern recognition, a commuting traffic analysis zone recognition method based on improved K-means algorithm is proposed. This method mainly includes three steps: dividing traffic analysis zones, generating flow transfer matrix between traffic analysis zones, and identifying commuting traffic analysis zone pairs. Referring to the existing traffic analysis zones division methods, a bottom-up division method based on fine-grained elements is proposed. In the recognition model of commuting traffic analysis zone pairs, the traffic flow and its dispersion coefficient during peak hours are taken as input features, and the commuting traffic analysis zone pairs are identified based on the improved K-means algorithm. Finally, an experimental verification is carried out based on the Chongqing taxi GPS data set, and the experimental results show that the method is effective.
