I'm trying to understand what kind of effect adding lanes has on the effectiveness of highway transport and I...can't. Suppose you have a single lane highway between A and B. In theory, its capacity is infinite.

Highways don't have intersections, so it's not like adding lanes increases the capacity of the roads between traffic intersections (avoiding gridlock). According to "credentialed" economists, the reason why adding lanes doesn't work is a concept called induced demand.

The idea is that by increasing supply (lanes), it will lower the cost of travel (by reducing traffic) thereby increasing demand, negating the new supply. I'm pretty suspicious of this idea, simply because I don't think that adding lanes after the 2nd does much to reduce traffic.pic.twitter.com/o0HthKCLmU

Additional lanes seem self-defeating. The cars in the far most left lane, to exit, will cross other lanes' traffic, slowing them. Is there something that I'm not understanding here? Or do lanes after the 2nd really give strongly diminishing returns?pic.twitter.com/gz4on8aYL7
