Two and Three Wheelers

Worldwide, the number of motorized two- and three- wheeled vehicles in city streets has been rapidly rising. In some Asian cities, motorcycles routinely account for more than 50 percent of the traffic. Meanwhile, road-engineering standards continue to be focused on four-wheel vehicles.

Designing streets to account for two- and three- wheelers could result in substantial benefits for all users, including minimizing casualties, optimizing traffic flows, reducing emissions, and freeing space for transit, non-motorized transport and public life.

ITDP works with experts, partner organizations, and government officials to:

• Build a coherent body of knowledge on two- and three- wheelers, including existing flows and road capacity characteristics, riding and parking behavior, and capacity to integrate with other modes.
• Evaluate experiences in innovating roadway design and regulatory guidelines, focusing particularly on integrating and/or separating motorized and non-motorized two and three wheelers with each other and with mixed traffic.
• Analyze efforts to encourage the use of less polluting vehicles, as well as efforts to prevent crashes and reduce congestion.
• Develop a set of rational standards and guideline recommendations.
• Implement exemplary pilot projects.
