论文摘要
电动汽车可能会在未来十年内主导电动运输，但是电动移动性集体动态对远程交通流量的影响仍然很大程度上是未知的。我们证明，如果充电基础设施有限或电动汽车密度很高，则会出现一种拥堵。这种拥堵仅通过通过排队避免行为在充电基础设施时间接相互作用而出现，这些行为 - 违反直觉 - 诱导占用的充电站的聚类以及将流动的相位分离为自由和拥挤的站点。由此产生的拥塞波总是向前进的方向传播，而通常向后传播的交通拥堵波从传统的交通拥堵中闻名。这些结果可以指导在不久的将来收取基础架构和决策支持应用程序的计划和设计。
Electric vehicles may dominate motorized transport in the next decade, yet the impact of the collective dynamics of electric mobility on long-range traffic flow is still largely unknown. We demonstrate a type of congestion that arises if charging infrastructure is limited or electric vehicle density is high. This congestion emerges solely through indirect interactions at charging infrastructure by queue-avoidance behavior that - counterintuitively - induces clustering of occupied charging stations and phase separation of the flow into free and congested stations. The resulting congestion waves always propagate forward in the direction of travel, in contrast to typically backward-propagating congestion waves known from traditional traffic jams. These results may guide the planning and design of charging infrastructure and decision support applications in the near future.
