Abstract

The introduction of autonomous vehicles (AVs) is predicted to potentially improve both transportation capacities and stimulate the worst impacts of car dependency. The concept of connected autonomous shared electric vehicle (CASE) has been introduced as an enabler of the collective mobility of the future that prioritizes ride-sharing and promotes multi-modal share with public transportation as the backbone. However, research in these areas is significant geographical imbalance upon contexts of the Global North. The future studies of CASE concepts are essential to fill the gap between fast technologies changing and long-term planning in technology's adopter like most of the Global South countries. This research explores different policy pathways in the long-term implication of CASE in Southeast Asia Mega-Urban Regions. Bangkok and Ho Chi Minh City have been selected as case studies due to their urban dynamics of rapid expansion of urbanization areas. This research proposes novel mixed methods to synergize multiple scenario buildings stages and find robust strategies. The exploratory processes take place in three stages of scanning driving forces, identifying critical uncertainties with bibliometric analysis, developing plausible scenarios with cross-impact analysis, and identifying robust strategies with spatial analysis. The issue on the categories of mobility solutions and governance approaches are critical uncertainties that are derived from bibliometric analysis. Then, two critical uncertainties were used to plot quadrants scenarios of everyman for himself scenario, affordable treats scenario, AVs-public transport hegemony scenario, and multi-modal prosperity scenario. The reconsideration of the current urbanization and urban mobility system in spatial analyses highlights a long path dependence of the absence of government intervention, weak transportation network, and lack of accessibility to public transportation. These inherent problems would likely lead the city to exclusiveness scenarios that fuel ignorance of CASE adoption and continue the high penetration rate of private transport. Indeed, the reaction of anticipatory governance will be unavoidable due to the need for public democratic discussion. Integrating CASE and mobility as a service is important to deliver a seamless user experience, personalized mobility plans, and fare payments on a single digital platform. This research recommends participatory planning to develop comprehensive urban-regional planning considering multi-level governments of local and regional levels in the metropolis and neighboring cities, private sectors, and communities. Initially, this research proposes scenario-based robust strategies underlying the idea of minimizing the maximum regret covering public rights-of-way, incentive zoning, and taxation strategies.
