论文摘要
近年来，共享自动化车辆（SAV）的技术已大大提高。但是，现有的SAV研究主要集中在系统设计上，而有限的研究研究了外源变量，尤其是城市形式的SAV性能的影响。因此，尚不清楚哪种关键的城市形式测量可能会影响SAV系统的可持续性。这项研究通过使用从286个城市收集的数据进行模拟实验来填补研究空白。这项研究确定了使用固定效应回归模型与模拟SAV性能相关的关键城市形式测量。结果表明，SAV效率更高，并且在具有更连接的网络和多样化的土地利用开发模式的密集城市中产生的VMT较少。模型结果可以帮助提供有关土地使用和运输政策的见解，以遏制将来SAV的不利影响，并将现有的SAV仿真结果推广到美国其他城市。
The technology of Shared Automated Vehicles (SAVs) has advanced significantly in recent years. However, existing SAV studies primarily focus on the system design while limited studies have examined the impacts of exogenous variables, especially urban form, on SAV performance. Therefore, it remains unclear what key urban form measurements may influence SAV system's sustainability. This study fills the research gap by conducting simulation experiments using data collected from 286 cities. This study identifies critical urban form measurements correlated with the simulated SAV performance using fixed effects regression models. The results suggest that SAVs are more efficient and generate less VMT in denser cities with more connected networks and diversified land use development patterns. The model results can help provide insights on land use and transportation policies to curb the adverse effects of SAVs in the future and generalize existing SAV simulation results to the rest of U.S. cities.
