Innovations impacting the future of transportation: an overview of connected, automated, shared, and electric technologies

ABSTRACT

This paper overviews emerging technology development by emphasizing Connected, Automated, Shared, and Electric (CASE) technologies. Existing literature on 15 CASE technologies is reviewed, and adds to the literature by consolidating important predictions of CASE-related technologies, services, and policies. Connected and automated technologies have not yet matured, and there remain many gaps in its abilities. Predictions include that shared mobility will have a large market share, electric technologies will replace internal combustion engines, and CASE-related services and policies will be used in more cities. A survey with 1,036 respondents conducted in April 2021 helps gauge how Americans make mode choices under various scenarios. Data analysis indicates that safety issues are the main factor that hinder people’s willingness to use CASE-related technologies, and the low cost encourages more users to choose shared mobility. Challenges that remain, and their associated impacts, are important to consider.
