Abstract

We compare charging station accessibility for different income groups in the San Francisco Bay Area. Using a microsimulation model, we estimate charging station accessibility under varying battery range scenarios, assuming different income groups have vehicles with different battery ranges. We conduct the analysis based on charging station availability in each traffic analysis zone in the Bay Area (N = 1442). Contrary to the general notion of unequal access to public charging stations across different income groups, we found that the disparity was minimal. Assuming a full fleet of EVs and the current level of charging infrastructure, the success rate for all income groups is low but similar using 2035 trip-level data. This finding highlights the need to build more charging infrastructure. To achieve a 95% charging success rate, we provide an estimate of the additional charging ports required in the San Francisco Bay Area.

人人平等充电：公共充电站是否存在收入差异？

我们比较了旧金山湾区不同收入群体的充电站可达性。假设不同收入群体拥有不同电池续航里程的车辆，采用微观仿真模型对不同电池续航里程下的充电站可达性进行了估计。我们基于Bay Area各交通分析区的充电站可用性进行分析（N = 1442）。与不同收入群体使用公共充电站的机会不平等的一般观念相反，我们发现这种差距很小。假设电动汽车车队齐全，充电基础设施现有水平，所有收入群体的成功率都很低，但根据2035年出行水平的数据，成功率相似。这一发现凸显了建设更多充电基础设施的必要性。为了达到95%的充电成功率，我们提供了旧金山湾区所需的额外充电端口的估计。

期刊介绍： The International Journal of Sustainable Transportation provides a discussion forum for the exchange of new and innovative ideas on sustainable transportation research in the context of environmental, economical, social, and engineering aspects, as well as current and future interactions of transportation systems and other urban subsystems. The scope includes the examination of overall sustainability of any transportation system, including its infrastructure, vehicle, operation, and maintenance; the integration of social science disciplines, engineering, and information technology with transportation; the understanding of the comparative aspects of different transportation systems from a global perspective; qualitative and quantitative transportation studies; and case studies, surveys, and expository papers in an international or local context. Equal emphasis is placed on the problems of sustainable transportation that are associated with passenger and freight transportation modes in both industrialized and non-industrialized areas. All submitted manuscripts are subject to initial evaluation by the Editors and, if found suitable for further consideration, to peer review by independent, anonymous expert reviewers. All peer review is single-blind. Submissions are made online via ScholarOne Manuscripts.
