Why didn’t the chicken cross the road?
Because pedestrian Level-Of-Service was below “C”.
A couple of years ago, I was listening to a friend explain why she left Rochester for Jacksonville. "I was tired of digging my car out of the snow." It occurred to me that the nexus between driving and winter weather may at least partially explain the decline of America’s northern Rust Belt.
Here’s why: car care and storage makes snow a bigger bother than might otherwise be the case: if you don’t have a heated garage, you have to dig your car out of the snow every day, and if you park on the street you may have to constantly move your car to accommodate municipal snow removal.
The graph below shows the most recent USDOT vehicle-travel data covering the last 25 years. Although vehicle-miles of travel (VMT) grew steadily during most of the Twentieth Century, in recent years the growth rate stopped and even declined a little. It is now about 10% below where it would have been had past trends continued.
Time is a limited and valuable resource. As much as possible, people should spend the precious hours of their lives in the most satisfying and productive possible ways. This has important implications for transportation planning, since most people spend a significant amount of time in transport, and travel time savings are often the greatest projected benefits of transport projects such as roadway and transit service improvements.
