摘要

人的流动主要以私家车为主,导致过多的碳排放、资源消耗、交通堵塞和污染。公共交通,如公共汽车、火车等,可以通过其较高的集合潜力缓解这些问题。然而,很多时候,人们认为公共交通不太方便,因而避而远之。在此,我们研究了一种双模式公共交通系统,该系统由一条轨道线路服务和一支按需提供线路服务站点接驳服务的班车队伍组成,旨在以较低的能源和资源消耗实现快速交通。通过基于代理的模拟和分析理论,我们证明了双模式公交系统确实有潜力在合理的服务质量下大幅降低人类出行的能源消耗。我们进一步研究了轨道沿线站点密度对双模式系统性能的影响。我们发现,在一定的实际技术参数范围内,增加停靠站往往会阻碍列车速度,但不会在服务质量和能源消耗方面显著提高双模式公交系统的整体性能。因此,减少现有铁路系统中的停靠站数量并实施双模式交通作为补充可能是有益的。

Impact of the density of line service stations on overall performance in Bi-modal public transport settings

Human mobility is mostly dominated by the use of private cars, leading to disproportionate carbon emissions, resource consumption, traffic jams, and pollution. Public transport, with buses, trains, etc., can mitigate these issues via its higher pooling potential. However, often times, public transport is considered less convenient and is therefore avoided. Here, we study a bi-modal public transport system consisting of a rail bound line service and a fleet of on-demand shuttles providing connections to the line service stops, aiming at fast transit at low energy and resource consumption. By means of agent-based simulations and analytical theory, we demonstrate that bi-modal transit indeed has the potential to significantly reduce energy consumption of human mobility at reasonable service quality. We further investigate the influence of the stop density along the rails upon the performance of the bi-modal system. We find that within a range of realistic technical parameters, additional stops tend to impede train speed without significantly enhancing the overall performance of bi-modal transit in terms of service quality and energy consumption. Hence, it can be beneficial to reduce the number of stops within an existing railway system and to implement bi-modal transit as a complement.
