Abstract

Rapid urbanization has posed significant burden on urban transportation infrastructures. In today's cities, both private and public transits have clear limitations to fulfill passengers' needs for quality of experience (QoE): Public transits operate along fixed routes with long wait time and total transit time; Private transits, such as taxis, private shuttles and ride-hailing services, provide point-to-point transits with high trip fare. In this paper, we propose CityLines, a transformative urban transit system, employing hybrid hub-and-spoke transit model with shared shuttles. Analogous to Airlines services, the proposed CityLines system routes urban trips among spokes through a few hubs or direct paths, with travel time as short as private transits and fare as low as public transits. CityLines allows both point-to-point connection to improve the passenger QoE, and hub-and-spoke connection to reduce the system operation cost. Our evaluation results show that CityLines framework can achieve both short travel time and high ride-sharing ratio.
CityLines:混合型轮辐城市交通系统
快速的城市化给城市交通基础设施带来了巨大的负担。在当今的城市中,无论是私人交通还是公共交通,在满足乘客对体验质量(QoE)的需求方面都存在明显的局限性:公共交通沿着固定的路线运行,等待时间和总运输时间都很长;私人交通工具,如出租车、私人班车和叫车服务,提供点对点的交通,行程费用很高。在本文中,我们提出了CityLines,一个变革性的城市交通系统,采用轮辐混合交通模式与共享班车。与航空公司的服务类似,拟议中的CityLines系统将城市旅行通过几个枢纽或直接路径在辐条之间进行,旅行时间与私人交通一样短,票价与公共交通一样低。CityLines既支持点对点连接以提高乘客的QoE,也支持轮辐连接以降低系统运营成本。我们的评估结果表明,CityLines框架既可以实现短的出行时间,又可以实现高的拼车比例。
