eli5: would adding more lanes to a freeway/busy street really ease congestion or would you still get bottlenecks?

1.16K views

I mean theoretically adding a lane or two should allow more cars to flow through, or would bad drivers still cause bottlenecks/gridlock despite the added capacity?

The problem isn’t the whole “more lanes means more people will drive” because we already have a bunch of people who drive and we DESPERATELY need more lanes and roadways, but traffic is a complex issue.

There’s a YouTube video about ghost signals that is a great way to look at traffic.. and most of it boils down to we are stupid monkey drivers and if we paid more attention to driving than to other things we would have significantly less traffic.

but in terms of bottlenecks? You’d still get them at the end of where the more lanes stop.

If you suddenly go from 4 lanes for example to 2 lanes (which is the case for an interchange near me where it’s 4 lanes going southbound but then it splits into east or west bound traffic 2 lanes each)

It creates a natural bottle neck.

The real solution to traffic is motorcycles and generally smaller cars.

I ain’t against cars by any means, but unless you NEED the bigger car, why bother having it
