About Our Research Unit

The Urban Transportation Research Unit is dedicated to research and educational activities related to transportation planning both domestically and internationally. Focusing on the movement of people, goods and information, our research interests cover a wide scope of topics ranging from theoretical and methodological research to practical implementation of new planning strategies. In recent years, major research topics include:

  • Transportation planning methods
  • Travel behavior and activity-based models
  • The relationship between urban form and transportation
  • Transportation planning in developing countries
