Excuse my french, but that's mostly bullshit. While it's true that cooperation would alleviate some of the slowdowns, they make some glaring mistakes and omissions.
I think insurance companies have convinced municipalities to put round-a-bouts in to limit liabilityExcuse my french, but that's mostly bullshit. While it's true that cooperation would alleviate some of the slowdowns, they make some glaring mistakes and omissions.
1) Rotaries - There's a rotary (or round-a-boot) about every 50 ft in Massachusetts. They don't work. If you doubt that, check-out the Concord rotary on Rt. 2. People think that rotaries allow traffic to keep moving at all times; but it doesn't.
2) Merges and exits - any way you cut it, if you are on a 3-lane highway, and a good amount of the vehicles are taking a 1-lane exit, traffic will slow down. Even the video shows that. Of course the cloverleaf doesn't help, but it would be very costly to have overpassing exit ramps.
You have fallen for an urban myth about those straight sections of the interstate.That's 100% accurate. Part of Eisenhower's plan with the highways was also to make sure that every few miles, the highway would be straight enough that they could land military aircraft on them if needed.
One of the other bad things that happened to cities when they added the highways was that if they didn't cut through the middle of downtowns and neighborhoods, they often sepearatd urban areas from their waterfronts. Look at New York, Cincinnati, San Francisco, and a bunch of other cities. The quality of life drops and it chases people out of cities to the suburbs. Cities are spending tons of money trying to correct the problem to help draw people back to live there again.
