Abstract:Shared transportation has grown significantly as renewed interest in urbanism and growing social and economic concerns have strengthened the need for sustainable alternatives. Shared autonomous vehicles (SAVs) are emerging as an alternative mode of transportation that could improve mobility and accessibility. However, the implications of SAVs on social equity are still under research and uncertainty exists regarding the potential adoption and market penetration within transportation-disadvantaged populations. The objective of this study is to assess the extent to which transportation-disadvantaged groups intend to adopt SAVs at two study areas with different density and travel characteristics, and to identify the potential geographical areas where SAVs could be effectively deployed. Public acceptance towards SAVs was assessed via stated preference surveys while a multi-spatial perspective approach was adopted to identify transportation disadvantaged groups in the two study areas. The results of the spatial market segmentation analysis showed that most of the respondents located in areas in Indianapolis identified as transportation disadvantaged are classified as early adopters and innovators, while the opposite conclusion was reached for the respective areas in Chicago, except for those closer to the downtown area. The results of this study could be useful to three stakeholders: ridesharing service providers, for their marketing and pricing-scheme decisions; public transportation planning agencies, for their policy making and investment decisions; and transportation planners, for infrastructure preparations towards the emergence of SAVs.
