Traffic (the book) says most Americans merge into traffic wrong when lanes reduce (from say 3 lanes to 2 lanes for example.)
The right way is waiting until you are at the very end of the lane that's reducing. When that happens up to 60% more cars per hour get through the bottle neck in heavy traffic and accidents resulting in killed or serious injury are reduced by up to 80%.
Bottom line having multiple entry points in a queue with multiple slow down points due to the multiple entry points is the cause of the reduced performance with the way most Americans do it.
Is there an illustration of how American’s merge? Or how the roads are designed for this?
I read this wrong... Let me see if I can find one.
This gives you an idea. Nothing special about the lane, it's like a lane anywhere else. We just overall merge early and at random distances causing chaos.
one of those being from INDOT (indiana) is funny. That example would break a state traffic law^1 that says you must merge as soon as you pass the lane ends sign
That's interesting.
