Analysis of Network Characteristics and Influencing Factors of Commuting Flow in Group Cities:A Case Study of Guiyang
Taking Guiyang as an example,based on the commuting flow data,this paper analyzes the characteris-tics of the commuting flow network at different scales in the region,evaluates the coupling and coordination rela-tionship between commuting flow network and bus facility network,and explores the influencing factors of commu-ting flow at different scales by using the improved gravity model.This paper aims to provide a reference for the op-timization of urban traffic systems and the layout of job-housing space in the group.The results show that:(1)The hierarchical structure of the commuter flow network is obvious,and the overall spatial connection pattern with the old city and the Guanshan Lake group as the core and gradually extending outward.(2)The coupling coordi-nation degree between the commuter flow network and transit facility network is generally low.Most areas are in an uncoordinated state,and public transport facilities need to be improved.(3)The number of people from the place of origin and the job-housing ratio of the place of arrival have a significant positive impact on commuting mobili-ty,and spatial distance is an important factor inhibiting commuting mobility.At the scale of the traffic zone,the high value of commuter flow usually occurs between two areas with unbalanced land use functions.
