That is ultimately how people will be motivated to use a transportation alternative. When driving one's own car takes a good 10 to 15 minutes longer each way than using buses or trains or whatever, that is when people will switch.

As Hank points out, 84% (in Portland, but likely similar in many places) prefer to drive single occupant cars, and that is just what they will continue to do until it becomes less preferable. It becomes less preferable when it takes significantly longer or when it costs just too damn much, which varies according to individual affluence.



The issue with that is that it negatively effects people who's jobs require daily additional travel once onsite to their work place. Which coincidentally are the same ones who foot the largest portion of the road work costs through gas taxes etc, which trimet does not pay in a proportionate sum. The cost per trimet rider is nearly 85 cents a mile, almost what a cab costs, light rail is 1.11 per rider without costing in the nearly 3 billion dollars in construction costs to date.
