Does the first/last-mile design matter for transit commuting compared to land use?
利用计算机视觉和XGBoost模型分析武汉街景与居民出行数据，发现首末段步行路径设计和居住地土地利用对促进公交通勤有显著非线性影响，且微观街道设计比单纯的土地利用干预更有效。
Pedestrian-friendly first/last-mile (FLM) path design has potential to promote transit use. Few studies focused on the design of transit FLM paths and comprehensively discussed the combined effects of land use attributes and FLM on transit commuting. Using computer vision techniques and the XGBoost model to analyze street view data and resident travel data in Wuhan, China, we elucidated the nonlinear association among work and residence place land use, FLM design, and individual commuting choices regarding transit, while controlling for individual demographic attributes. Our finding demonstrates the effectiveness of focusing on micro-street design in promoting transit commuting. The first-mile design attributes and residential land use attributes had a greater impact. Furthermore, almost all built environment attributes were nonlinearly associated with transit commuting. The findings emphasize urban design interventions that improve street-level walkability. In comparison, transit-oriented built environment interventions centered solely on land use may struggle to achieve satisfactory results.
