Cost benefit analysis of technology and replacement options for 2-stroke three wheelers in the Philippines

Motorized three-wheelers play an important role in various Asian cities and towns. In the Philippines, these three-wheelers are called tricycles and primarily serve as feeders for residential and minor roads. However, in several towns in rural areas these tricycles serve as the main mode for transporting people all around town. This study focuses on the environmental, financial and social cost benefit aspects of the technologies concerned and the various phase-out options. It also includes an overview of an ongoing study to replace 2-stroke tricycles in Mandaluyong City, Metro Manila.
