Abstract:Autonomous vehicles (AVs) could have both positive and negative impacts on public health. The most notable benefits relate to reduction in crashes and pollutant emissions. Conversely, AVs can limit opportunities for active travel and associated health benefits. If the adoption of the AV or shared AV technology is not adequately designed, it could likely lead to increases in vehicle-miles traveled (VMT). This may decrease physical activity and aggravate air pollution, and in turn, exacerbate non-communicable diseases, which are nowadays responsible for two-thirds of deaths globally. This study evaluates the relationship between ridesharing (as a proxy for shared travel behavior) and active travel behavior (often measured as the number of trips made by walking or biking) and identifies personal health-related outcomes associated with the adoption of AVs. The study also discusses the built environment settings that are more likely to surround early adopters of AVs. Two metropolitan statistical areas served as case studies. A variety of strategies are recommended to maximize the benefits of SAV technology and mitigate any adverse impacts that this technology may bring.
