IMPLICATIONS TO URBAN REGENERATION BASED ON THE INFLUENCE OF URBAN BLOCK EVOLUTION ON TRAFFIC CONGESTION:A CASE STUDY OF HUAI'AN,JIANGSU PROVINCE
With multiple dimensions,urban block evolution may lead to various urban problems.Therefore,exploring relevant influences is a key prerequisite for implementing urban regeneration actions.Based on multi-source spatio-temporal data and applying approaches,including dimensional reduction,correlation analysis,and Geography Weighted Regression,this paper conducts a case study on 107 urban blocks in Huai'an City,Jiangsu Province and develops a multi-dimensional complex element system with several dimensions,including spatial capacity,transportation facilities,daily commute,socio-economy,and public traffic.Then it explores the spatio-temporal influence mechanism of urban block evolution on traffic congestion.The influence mechanism indicates that spatial capacity and daily commute have significantly positive influence,public traffic has significantly negative influence,and transportation facilities and socio-economy have insignificant influence.Following this influence mechanism and considering foreseeable physical changes in urban blocks,official guidance,and practical experience of urban regeneration,scenario simulation is conducted to explore the potential increase in spatial capacity in future regeneration of urban blocks,which can be considered as implications to urban regeneration.
