虽然一些压缩天然气（CNG）车队在其基地设有中央加油站，但其他车队在其车队仓库缺乏加油能力，必须依赖公共加油站。为了了解这种分散的加油行为，我们在洛杉矶地区的六个公共加油站调查了133名CNG车队车辆的司机。近三分之一的CNG车队司机完全依赖公共加油。对于每个驾驶员的加油行程，我们使用GIS来比较所选站点与驾驶员车队基地的接近程度，以及它们与上一站和下一站之间的最短路径相对于所有其他站点的偏差。这种显示偏好的方法表明，车队司机选择了车站与最接近基地的车站以6：1的比例最小的偏差，尽管这个比例因司机的中央加油的可用性和车辆和路线的类型而异。鉴于公共加油站对于满足其他车队和消费者的分散加油需求仍然至关重要，这些发现对正在考虑采用CNG车辆和在其基地托管中央加油基础设施的额外投资的车队具有重要意义。
While some compressed natural gas (CNG) vehicle fleets have a station at their base for central refueling, others lack refueling capability at their fleet depot and must rely on publicly available stations. To understand this kind of decentralized refueling behavior, we surveyed 133 drivers of CNG fleet vehicles at six public stations across the Los Angeles region. Nearly one-third of CNG fleet drivers were solely reliant upon public refueling for their operations. For each driver's refueling trip, we used GIS to compare the chosen station's proximity to the driver's fleet base and their deviation from the shortest path between their previous and next stops relative to all other stations they could have chosen. This revealed-preference approach shows that fleet drivers chose the station with the smallest deviation over the station closest to base by a 6:1 ratio, though this ratio varied by the driver's availability of central refueling and type of vehicle and route. Given that public stations remain essential to meeting decentralized refueling demand for other fleets as well as consumers, these findings have important implications for fleets that are both considering the adoption of CNG vehicles and the additional investment of hosting central refueling infrastructure at their base.
