This book offers comprehensive state-of-the-art knowledge of how ride-hailing applications (RHAs) are changing the landscape of urban mobility in developing Southeast Asia by examining the disruptions they cause, the impacts of RHAs on the transportation system, and public policy responses aimed at mitigating these impacts. Providing new perspectives on the familiar issues by taking the local contexts of middle-income SEA into account, where abundant and diverse modes of informal transportation thrive amidst rapid urbanization and motorization, the book also draws lessons based on empirical evidence on how public interventions can benefit urban mobility for other developing countries. Each city-specific chapter sets the stage by overviewing the city and its transportation system, and delves into the specifics of its RHA market, such as market structure and demand characteristics. Impacts of RHAs on other transportation operators as well as responses from affected parties are discussed, followed by the ensuing regulatory efforts and their outcomes. Findings from each city are internationally compared and lessons drawn from them that are useful for policymaking. The book will present insights into useful and effective policy interventions pertaining to RHAs, including how the new technology may affect the infrastructure investment decision and how RHA may be leveraged as an intervention tool in urban mobility in developing countries. Digital Transport Platforms and Urban Mobility provides academics and upper level students with in-depth knowledge and practices of the disruptive technology in urban transportation due to the advent of mobile ride-hailing applications in Southeast Asian countries. It will be an invaluable resource for all those interested in transportation planning and policy, urban and regional planning, with a particular emphasis on sustainability.
