Our objectives in this research study are: 1) quantify the benefits of carsharing for low-income users; 2) evaluate the effectiveness of policies targeting spatial access (e.g., parking policies, designation of service areas); and 3) review other social equity initiatives taken by carsharing operators (e.g., low-income discounts, educational training) and impacts on user demographics. We use two one-way, free-floating carsharing services as case studies: a survey of GIG (Get In and Go) Car Share users in Oakland, CA from 2018 (n = 218), and a survey of car2go users (now called ShareNow) in five North American cities from 2015 (n = 9497). We analyze these surveys using descriptive statistics, hypothesis testing, and geographic information systems (GIS) mapping. We find significantly more low-income respondents in Oakland do not have a personal vehicle (70%) compared to high-income respondents (44%). Meanwhile, 62% of our sample was Caucasian, and 41% earned an annual household income of more than $100,000, similar to results of the car2go survey from 2015, indicating that the demographics of one-way carsharing users have not changed much over time. We find that policies expanding carsharing service areas into equity priority zones can potentially attract new members. Washington, D.C. and Oakland included equity service area requirements in carsharing permits and had a higher percent of users residing in equity priority zones (21% and 33%, respectively), compared to Calgary and Vancouver that did not (12% and 4%, respectively). However, the demographics of carsharing users still do not reflect the demographics of equity zones. Policies to increase spatial access of carsharing are insufficient on their own to improve social equity in carsharing. Based on findings from previous carsharing equity pilots, policy initiatives such as discounted memberships for low-income users and hands-on educational outreach are needed to advance social equity. 收起
