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.
Does the book mention that the Zipper merge is inherently flawed as it relies on drivers to be far more cooperative than they are?
Yeah. So, like communism, the entire theory breaks down when humans are actually involved.
Sadly, there are many places in Canada with the same problem. I blame Americans for that, too.
