Synergistic Optimization Mechanism of Transportation and Land Use Factor Supply on the Spatial Characteristics of Commuting Circle:A Case Study of Wuhan
Against the backdrop of increasingly acute transportation-related challenges constraining the high-quality development of large cities,research on the spatial characteristics of commuter zones based on residents'spatiotemporal big data provides an effective perspective for the refined allocation of transportation and land use elements.Taking Wuhan as an example,this study utilizes mobile information data to identify two types of commuter zones:commercial(service)and industrial.It then explores,through scenario simulation,the collaborative impact of transportation and land use element supply on the morphological changes of commuter zones and their internal traffic structure characteristics.The findings reveal that:(1)Commercial(service)commuter zones exhibit two structural patterns:"ring-layer+axial-belt"and"core agglomeration+ring-layer expansion";industrial commuter zones display a"spindle layout",with more apparent commuting directionality.(2)The supply of rail transit elements significantly affects the shape of commuter zones and extends commuting distances;a compact layout of land use elements facilitates the agglomeration of commuter zone layers,reducing commuting distances and time spent.For both types of commuter zones,the study proposes optimization strategies for improving the layout of transportation facilities and supporting service facilities,from the perspective of promoting green travel within commuter zones.
