Abstract

Emerging autonomous driving technologies are claimed to create new opportunities for realizing smart and sustainable urban mobility initiatives. In this perspective, some studies identified shared autonomous vehicles (SAVs) as being a crucial element of on-demand mobility services. There is, however, limited evidence from practice on what roles SAVs play in delivering smart urban mobility. In other words, SAV in the context of smart urban mobility is an understudied area of research with limited review studies. To bridge this gap in the literature, this study aims to investigate and map out the service attributes and impacts of SAVs on urban mobility, infrastructure and land use, travel behavior, and the environment. As the methodological approach, the paper adopts the systematic literature review technique. The study findings reveal that: (a) Providing dynamic ridesharing services could result in significant reduction of SAV fleet size, congestion, travel cost, parking demand, vehicle ownership, and emissions; (b) Positive environmental outcomes could be enhanced with full electrification of SAV fleet through renewable energy charging; (c) Integration of SAV, as a smart urban mobility system with dynamic ridesharing services, could promote sustainability and social and transportation equity, and their adoption. In the light of the findings, this study advocates the consolidation of urban/transport policy to achieve desired urban mobility outcomes.

摘要

据称，新兴的自动驾驶技术为实现智能和可持续的城市交通计划创造了新的机会。从这个角度来看，一些研究将共享自动驾驶汽车 (SAV) 确定为按需移动服务的关键要素。然而，实践中关于 SAV 在提供智慧城市交通方面所起的作用的证据有限。换句话说，智能城市交通背景下的 SAV 是一个研究不足的研究领域，审查研究有限。为了弥合文献中的这一差距，本研究旨在调查和绘制 SAV 对城市交通、基础设施和土地利用、出行行为和环境的服务属性和影响。在方法论上，本文采用了系统的文献综述技术。研究结果表明：(a) 提供动态拼车服务可以显着减少 SAV 车队规模、拥堵、出行成本、停车需求、车辆拥有量和排放量；(b) 通过可再生能源充电使 SAV 车队完全电气化可以增强积极的环境成果；(c) SAV 作为具有动态拼车服务的智能城市交通系统的集成，可以促进可持续性和社会和交通公平及其采用。根据调查结果，本研究提倡整合城市/交通政策，以实现理想的城市交通结果。(b) 通过可再生能源充电使 SAV 车队完全电气化可以增强积极的环境成果；(c) SAV 作为具有动态拼车服务的智能城市交通系统的集成，可以促进可持续性和社会和交通公平及其采用。根据调查结果，本研究提倡整合城市/交通政策，以实现理想的城市交通结果。(b) 通过可再生能源充电使 SAV 车队完全电气化可以增强积极的环境成果；(c) SAV 作为具有动态拼车服务的智能城市交通系统的集成，可以促进可持续性和社会和交通公平及其采用。根据调查结果，本研究提倡整合城市/交通政策，以实现理想的城市交通结果。
