Ms. Johnson said the question for transportation planners is, how do we get people out of their cars?

The state and regional transportation planners have worked to adapt to this change since the 1940s.

When the project was finally canceled in 1974, local transportation planners began to look at completing I-205.

A lot must happen, but transportation planners hope that by 2010 the line will carry 18,000 commuters each day.

Transportation planners say this is too expensive, with bus and van services more feasible.

One principal element of this change is the way transportation planners and engineers address speed.

"This has not been supported by transportation planners, law enforcement officials and local officials," he said.
