Lesson Learned

Researchers evaluating the Nagoya pilot program offered the following lessons learned.

When implementing traveler information systems that encourage individuals to modify their travel behavior and use non-auto transport such as walking, bicycles, and public transportation:
  • Minimize the amount of data that must be recorded and manually input by travelers. Cell phones with Internet and GPS functions can be used as TDM (Transportation Demand Management) devices to improve the cost-effectiveness of collecting travel behavior data. These TDM devices should not burden the user with complicated operations, a range of input items, and excessive functionality. Consider designs that can be easily used by the elderly.
  • Offer personalized advice and feedback based on action. Develop an automated expert system to identify and diagnose a variety of travel behavior patterns. Feedback should include an assessment of planned versus actual travel behavior and include recommendations for multi-modal route options and timing alternatives.
  • Provide users with good planning tools. Planning tools should be easy to use, identify the most efficient commuter routes, and support multi-modal travelers.
The pilot test results were positive. Participants were generating approximately 20 percent fewer carbon dioxide emissions compared to participant emissions at the beginning of the pilot. In general, the reduction was attributed to changes in modal share due to users switching from cars to public transportation, walking, or bicycles. Lessons learned from the Nagoya pilot test offer guidance on achieving significant emissions reduction and, thus, on improving environmental sustainability.
