在美国，公共交通车辆具有非常低的平均负载系数（10.1-12.4%），导致座位容量的过度浪费和每乘客英里服务的燃油经济性差。2019冠状病毒病疫情严重加剧了这一问题，疫情高峰期导致全国过境乘客量减少超过70%。另一方面，疫情加速了电子商务的快速发展，给最后一公里的交付带来了巨大压力。将过境服务与最后一英里物流相结合的多式联运系统为更好地利用/共享车辆能力和支持基础设施提供了一个有前途的解决方案。在这里，我们展示了这样的系统可以基于自主模块化车辆技术（AMVT）来实现。AMVT的核心是能够操作一组模块化自动驾驶车辆或吊舱，这些车辆或吊舱可以在真实的时间内移动、驻扎、加入和分离。将模块化与自主性相结合，可以实现协同模式及其他模式。我们描述了一个AMVT双模系统，提供综合的公共交通和最后一英里的物流服务与车队的吊舱，并讨论相关的研究挑战和机遇，研究方法，和现实世界的采用问题。
In the United States, public transit vehicles have a very low average load factor (10.1–12.4%), resulting in an excessive waste of seat capacity and poor fuel economy per passenger mile served. This problem is gravely exacerbated by the COVID-19 pandemic, which at its peak had caused more than 70% reduction in transit ridership nationwide. On the other hand, the rapid uptake of e-commerce, also accelerated by the pandemic, has put tremendous pressure on last-mile delivery. A co-modality system that integrates transit services with last-mile logistics offers a promising solution to better utilization/sharing of vehicle capacity and supporting infrastructure. Here we show such a system may be implemented based on Autonomous Modular Vehicle Technology (AMVT). At the core of AMVT is the ability to operate a fleet of modular autonomous vehicles or pods that can be moved, stationed, joined, and separated in real time. Coupling modularity with autonomy is poised to enable co-modality and beyond. We describe an AMVT bimodality system that provides integrated public transit and last-mile logistics services with a fleet of pods and discuss relevant research challenges and opportunities, research approaches, and real-world adoption issues.
