Flip side of induced demand
- Yet another article citing numerous cases where removing motor vehicle capacity actually reduced congestion--includes freeway removals. This is the flip side of "induced demand," a well-known phenomenon among traffic engineers whereby adding capacity entices more people to drive more miles and thus cause more congestion.
=v= Thanks, I try to explain traffic evaporation (and Braess's
Paradox) to people, and it would be nice to have a resource like
this to point to. I find that a lot of people can grasp induced
demand, but any notion of removing car accommodation will strike
fear into the very depths of their petroleum-powered being.
=v= San Francisco has seen traffic evaporation on a grander
scale than the parklet mentioned in the video at the website.
Two freeways were damaged in the 1989 earthquake, and parts
were eventually torn down. The local media freaked out, and
even predicted "post-apocalyptic" traffic conditions, but it
didn't materialize. Instead we saw traffic evaporation.
