Abstract
Motorcycle taxi plays an important role as one of public transportation modes in Bangkok. However, in the past, the motorcycle taxi service has been operated under unregulated condition that causes various problems to motorcycle taxi drivers and users. In 2005, the Thai government has imposed the regulations upon motorcycle taxi service that included motorcycle taxi drivers? registration and fare rate. This makes Thailand becoming the first country in the world that regulates motorcycle taxi service. This study examines the motorcycle taxi drivers and service conditions before and after having imposed the regulations. The results reveal that the motorcycle taxi drivers? behavior and its service system have been changed obviously after the imposition. Also, this study proposes the equation that could represent the system of motorcycle taxi service which could be applied for future planning condition perspective.
