New roads can cause congestion
New Scientist - New roads can cause congestion viaMeshForum
Traffic should flow best in cities when only a limited number of roads lead to the centre. This counter-intuitive finding could allow planners to prevent gridlock by closing roads rather than building new ones.
It's not counter-intuitive to me. Seems totally clear to me that when there are more roads or more lanes, there's more traffic and thus more congestion. I'd like to see close or narrow roads for cars but leave the pavement in place for bikes. Lakeshore drive would be a good place to start. Turn one lane each way into lanes and everyone would see the benefits nearly right away. Too bad they couldn't have kept Wacker Drive closed to cars after it was closed for 2 years to be rebuilt. Traffic in the loop during that time showed that the road simply isn't needed for cars. Let's see a balanced policy that works for all of us!
