This report investigates current trends in the MaaS market in North America and how the public sector can most effectively collaborate with private companies to improve regional accessibility while protecting public interestsーsuch as equal access to transportation and job opportunities, effective traffic management to enable economic agglomeration, and safety. To clarify the opportunities for and challenges of this new technology, I study MaaS programs promoted by three leading transportation authorities: Los Angeles County Metropolitan Transportation Authority (LA Metro), Dallas Area Rapid Transit (DART), and Tri-County Metropolitan Transportation District of Oregon (TriMet). Through a careful review of the literature and in-person interviews with people involved with these three authorities, I draw lessons learned from the ongoing programs and propose three potential directions that transit agencies and local governments can take in developing future mobility strategies related to MaaS.
