Chart of the Day: Induced Travel Hypothesis



All right, here’s a doozy for you. This is a chart that I pulled out of one of David’s engineering articles. I’m not sure I understand it. Maybe you can explain it to me.

The best I can do is that this chart shows that demand for travel (e.g. the desire to drive in a car down the road or freeway) is not constant, but shifts in relation to the supply of roadway (i.e. congestion). In other words, if we build more roads, people will drive more because it’s easier. If we build fewer roads, people will drive less because its more difficult.

This seems really important, somehow.
