论文摘要
交通拥堵是运输行业面临的主要挑战之一。尽管此问题具有较高的经济和环境成本，但必须有效地设计多层网络基础架构中乘客的最佳途径。我们考虑一种基于最佳运输理论的方法，最好沿着比道路更碳效率的层途径路线路线。铁轨。通过分析这种选择对性能的影响，我们发现与最短路径最小化相比，这种方法可大大减少碳排放。同样，我们发现这种方法更均匀地分配流量，从而减轻了交通拥堵的风险。我们的结果阐明了在最佳运输理论指导的层次上灵活分配流量的影响。
Traffic congestion is one of the major challenges faced by the transportation industry. While this problem carries a high economical and environmental cost, the need for an efficient design of optimal paths for passengers in multilayer network infrastructures is imperative. We consider an approach based on optimal transport theory to route passengers preferably along layers that are more carbon efficient than the road, e.g. rails. By analyzing the impact of this choice on performance, we find that this approach reduces carbon emissions considerably, compared to shortest-path minimization. Similarly, we find that this approach distributes traffic more homogeneously thus alleviating the risk of traffic congestions. Our results shed light on the impact of distributing traffic flexibly across layers guided by optimal transport theory.
