Abstract

In mobility-on-demand services, the number of vehicles needed is often determined by peak demand during rush hours, leading to prolonged vehicle idle times during off-peak periods. This surplus capacity presents an opportunity for vehicles to perform additional tasks, potentially enhancing system efficiency and reducing the overall number of vehicles needed in cities. Leveraging agent-based modeling, we evaluate the effectiveness of vehicles catering to on-demand rides and food deliveries in two real-life scenarios: Cambridge, MA, USA, and San Sebastian, Gipuzkoa, Spain. The results show that multifunctional behavior can lead to reduced fleet sizes, with context-specific exceptions. Additionally, a strategic dispatching algorithm is introduced that demonstrates reductions in wait times and overall distances traveled. This research contributes to the understanding of the performance of multifunctional fleets in diverse urban contexts, informing the development of sustainable and resource-efficient mobility systems.

多功能轻型自动驾驶汽车：基于代理的研究

在按需移动服务中，所需的车辆数量往往取决于高峰时段的需求，从而导致车辆在非高峰时段长时间闲置。这种剩余容量为车辆执行额外任务提供了机会，有可能提高系统效率并减少城市所需的车辆总数。利用基于代理的建模，我们在两个真实场景中评估了车辆按需乘车和送餐的有效性：美国马萨诸塞州剑桥市和西班牙吉普斯夸省圣塞巴斯蒂安市。结果表明，多功能行为可以减少车队规模，但也有特定环境下的例外情况。此外，研究还介绍了一种战略调度算法，该算法可减少等待时间和总行程。这项研究有助于人们了解多功能车队在不同城市环境中的表现，为开发可持续的资源节约型交通系统提供信息。

期刊介绍： In our first issue, published in 1972, we explained that this Journal is intended to promote the free and vigorous exchange of ideas and experience among the worldwide community actively concerned with transportation policy, planning and practice. That continues to be our mission, with a clear focus on topics concerned with research and practice in transportation policy and planning, around the world. These four words, policy and planning, research and practice are our key words. While we have a particular focus on transportation policy analysis and travel behaviour in the context of ground transportation, we willingly consider all good quality papers that are highly relevant to transportation policy, planning and practice with a clear focus on innovation, on extending the international pool of knowledge and understanding. Our interest is not only with transportation policies - and systems and services – but also with their social, economic and environmental impacts, However, papers about the application of established procedures to, or the development of plans or policies for, specific locations are unlikely to prove acceptable unless they report experience which will be of real benefit those working elsewhere. Papers concerned with the engineering, safety and operational management of transportation systems are outside our scope.
