The effort would review current literature and research that address these issues, extract the vital information, describe good examples and present the findings in an understandable way that would be meaningful in the public debates on transportation investment. The following are some of the elements that should be included:

• Description of how the modes contribute to the nation's productivity;
• Congestion's negative impact on the economy;
• Transportation's contribution to environmental protection;
• Transportation's contribution to past and future mobile source air emissions;
• Description of what constitutes quality of life and how transportation can enhance quality of life;

• Integration of transportation design standards and community goals;
• Choices between modes such as pedestrian, bicycle, auto and transit, etc.; and
• How overall social concerns are addressed in transportation plans and programs.
