New research recently completed for the Transit Cooperative Research Program provides the ammunition to build TODs that take the benefits of transit into account. The study completed by PB PlaceMaking, Dr Robert Cervero, The Urban Land Institute and the Center for Transit Oriented Development looked at how automobile use of residential TODs compared to conventional development.
The research looks at the actual transportation performance of 17 built TOD projects. This was done by counting the passage of motorized vehicles using pneumatic tubes stretched across the driveways of TOD housing projects of varying sizes in four urbanized areas of the country: Philadelphia/N.E. New Jersey; Portland, Oregon; metropolitan Washington D.C.; and the East Bay of the San Francisco Bay Area.
Results of this research show TOD-housing produces fewer automobile trips in the four urbanized areas. The research confirms the ITE trip generation and parking generation rates over estimate automobile trips for TOD housing by 50%.
