In this paper, we apply an optimization-based approach to locate electric vehicle (EV) fast charging stations that prioritize the deployment of stations considering the designated EV corridors. A designated corridor is a segment of a highway selected for EV charging infrastructure deployment to increase the adoption of EVs. We formulate the problem such that candidate charging stations on corridors are prioritized over the other candidate station locations outside the corridor. We also introduce two new objective functions based on corridor-utilizing and corridor-weighted traffic flow concept and a new constraint that primarily focuses on the corridor building. These new objectives fit better for enabling EV corridors when the underlying objective is to locate chargers along these corridors with high density. We conduct numerical experiments using the Maryland highway network, major population centers, and select EV corridors as input. Experiment results suggest that the traditionally used objectives in the literature, maximizing traffic flow and maximizing vehicle-miles traveled (VMT), may not be well-suited for corridor building. However, a corridor-focused objective function causes the removal of many O-D pairs from consideration; hence, its impact on the overall EV flow refueled is significant as well. Experiment results also indicate that corridor prioritization is crucial for selecting a solution with more stations on corridors.

在本文中，我们应用一种基于优化的方法来定位电动汽车 (EV) 快速充电站，考虑指定的电动汽车走廊，优先部署充电站。指定走廊是选择用于电动汽车充电基础设施部署的高速公路路段，以增加电动汽车的采用率。我们制定问题，使走廊上的候选充电站优先于走廊外的其他候选充电站位置。我们还引入了两个基于走廊利用和走廊加权交通流概念的新目标函数，以及一个主要关注走廊建设的新约束。当基本目标是在这些走廊上以高密度定位充电器时，这些新目标更适合启用 EV 走廊。我们使用马里兰州高速公路网络、主要人口中心进行数值实验，并选择 EV 走廊作为输入。实验结果表明，文献中传统使用的目标，即最大化交通流量和最大化车辆行驶里程 (VMT)，可能并不适合走廊建设。然而，以走廊为中心的目标函数会导致许多 OD 对被排除在考虑之外；因此，它对整个 EV 加油流量的影响也很大。实验结果还表明，走廊优先级对于选择走廊上有更多站点的解决方案至关重要。最大化交通流量和最大化车辆行驶里程 (VMT)，可能并不适合走廊建设。然而，以走廊为中心的目标函数会导致许多 OD 对被排除在考虑之外；因此，它对整个 EV 加油流量的影响也很大。实验结果还表明，走廊优先级对于选择走廊上有更多站点的解决方案至关重要。最大化交通流量和最大化车辆行驶里程 (VMT)，可能并不适合走廊建设。然而，以走廊为中心的目标函数会导致许多 OD 对被排除在考虑之外；因此，它对整个 EV 加油流量的影响也很大。实验结果还表明，走廊优先级对于选择走廊上有更多站点的解决方案至关重要。
