2. Transportation Demand Management
Policies to reduce automobility and balance multiple modes
“Carrots” and “Sticks” to change travel behavior
Greater focus on efficient use of existing infrastructure than expansion of new infrastructure

3. Matching Goals to Time Frame
TDM may focus on short term results (mitigation)
Auto restrictions to clean air
Long term congestion management
Road pricing or land use development

4. Who Makes TDM Policy?
TDM implementation will vary by region
Employer-based services
Use of road toll revenue
Roll of regional transit provider
Land use regulations

5. Transportation Management

6. Changes in Trip Type
TDM is commonly thought of as a commuting strategy:
Commuting is declining as a share of total travel in many cities
TDM policies must be careful not to “destroy” economically beneficial trips

7. Parking is Critical Ample parking makes driving cheap and easy
Encourage shared parking
Eliminate parking requirements
Offer parking cash out to employees
Promote redevelopment of parking lots

8. Key Takeaways for Practice
Policies that raise the price of driving are most effective
As long as driving is cheap, cities will struggle to reduce automobility
TDM policies must be considered with the local context
