论文摘要
运输贡献了所有温室气体排放的很大一部分。减少这种排放的一种方法是修改车辆的路线选择，以最大程度地减少其燃油消耗或排放，这被称为生态切割。大多数生态路线是基于选择最大程度减少其个人燃料消耗或排放的途径的车辆。胸罩悖论表明，当车辆选择最小化其个人目标的路线时，由于拥塞模式的变化，总体效应可能会矛盾地从而产生相反的净效应。我们构建了一个多类用户平衡模型，其中一些车辆使用生态路线，而另一些车辆则试图最大程度地减少其个人旅行时间。使用此模型，我们表明存在盲文悖论用于生态路由。如果大量车辆试图最大程度地减少其燃油消耗或排放，则总燃油消耗或排放可能会增加。然后，我们在公开可用的城市网络数据上解决了多类用户平衡，并发现生态布线会导致某些城市网络上的燃料消耗和排放量增加。
Transportation contributes a substantial fraction of all greenhouse gas emissions. One approach for reducing such emissions is to modify vehicles' route choices to minimize their fuel consumption or emission, which is known as eco-routing. Most eco-routing is based on vehicles choosing routes that minimize their individual fuel consumption or emissions. The Braess paradox demonstrates that when vehicles choose routes to minimize their individual goals, the aggregate effect may paradoxically result in the opposite net effect due to changes in congestion patterns. We construct a multiclass user equilibrium model in which some vehicles use eco-routing and others seek to minimize their individual travel times. Using this model, we show that the Braess paradox exists for eco-routing. If a large number of vehicles are trying to minimize their fuel consumption or emissions, the total fuel consumption or emissions may increase. We then solve the multiclass user equilibrium on publicly available city network data, and find that eco-routing results in increases in fuel consumption and emissions on some city networks as well.
