Despite contributions to reducing private car dependency and carbon emissions, impacts of transit-oriented development (TOD) on ride-hailing usage are largely overlooked in existing studies. Using massive ride-hailing trips data in Chengdu, the influence of subway proximity on vehicle kilometers traveled (VKT) and corresponding CO emissions of ride-hailing is examined at the disaggregated level. Similarly, moderated multiple regression is adopted to investigate the interaction effects of subway proximity at pick-up and drop-off on VKT of ride-hailing. Results suggest that for each additional kilometer in subway proximity at pick-up/drop-off position, the VKT of ride-hailing trips is reduced by 0.315 km/0.273 km, resulting in the CO emission reduction of 0.063 kg/0.055 kg. Moreover, the influence of pick-up proximity on VKT change is negatively moderated by drop-off proximity and vice versa. Our results suggest that the carbon emission reduction can benefit from "T (Transit)" however the problem of regional imbalances in "D (Development)" needs to be addressed.
尽管向公共交通导向型发展（TOD）模式转变有助于减少对私家车的依赖和碳排放，但现有研究在很大程度上忽视了 TOD 对打车出行的影响。本文利用成都市海量的打车出行数据，在细分层面上考察了地铁可达性对打车出行里程（VKT）和相应 CO2 排放量的影响。同样，采用了调节多元回归来研究上下车站点地铁可达性对打车出行 VKT 的交互影响。结果表明，在上下车站点，地铁可达性每增加一公里，打车出行里程将减少 0.315 公里/0.273 公里，相应的 CO2 排放量减少 0.063 公斤/0.055 公斤。此外，上下车站点的可达性对 VKT 变化的影响存在负向调节作用，反之亦然。我们的研究结果表明，虽然“T（交通）”可以带来碳减排效益，但“D（发展）”方面的区域不平衡问题仍需解决。
