Nationwide, the average worker spends 24.7 minutes, each way, traveling to and from work. People who drive alone spend 24.4 minutes; people who carpool spend 28.0 minutes; people who walk take 11.9 minutes; and people who take transit take 48.7 minutes.
In other words, people who take transit spend almost exactly twice as much time en route as people who drive alone. Why? The simple answer is that transit is slower. But this flies in the face of the idea that people have a travel-time budget that limits the total amount of time they are willing to spend traveling each day (or week).
Is the travel-time budget idea wrong? Or do people who take transit have different travel-time budgets than people who drive? Or is the travel-time budget different if, when you are traveling, you can relax and read your iPad or do something else entertaining than if you have to face the work and stresses of driving?
