From"Station-City Integration"to"Corridor Integration":TOD Framework and Model Optimization from the Perspective of Space of Flows
Transit-oriented development(TOD)is a crucial planning approach for ad-dressing urban sustainable development challenges.However,the theoretical mecha-nism and practical effectiveness of TOD require further improvement.The paper re-views the TOD concept and its key mechanisms,emphasizing that integrating public transit and land use is central to TOD.However,the fundamental purpose of TOD is not simply compact,mixed,and high-intensity land development,but rather en-hancing the attractiveness of public transit to residents and promoting urban green,low-carbon,and sustainable development.To address implementation challenges of TOD policies in China,the paper proposes a theoretical framework encompassing travel behavior,public transit systems,and land use from the perspective of the space of flows.Based on empirical findings about community structures influenced by transit travel behavior,the paper proposes an optimized TOD model with the"corridor"as the primary planning unit.This approach aims to achieve more bal-anced passenger ridership on rail transit and provide urban residents with better choices in employment,residence,and recreation.
