Adding lanes may not cut congestion in the long term, but it can increase throughput and overall utility by moving more people and goods.

- ronbenton 10mo agoI don't doubt it. It is quite a while ago so I don't fully recall the talk that my professor gave, but I don't believe he intended to mean adding lanes was useless, just that they didn't help with congestion of the particular roadway
- bluGill 10mo agoIf adding lanes doesn't help you didn't add enough. People live in a city to do things and you need to enable that by preventing congestion. i don't know how to afford the 50 more lanes that most cities need though. I suggest better transit.
- loglog 10mo agoRemoving parts of the city to add more lanes will also help decreasing demand - it's a win-win!

- JumpCrisscross 10mo ago> how do you see that something is downvoted? You can’t directly. If the comment goes negative, it get greyed out. (In many cases, people are complaining about a comment they like not being the top comment.) Either way, complaining about the voting is against the guidelines and thus flaggable. That causes your comment to get marked as flagged.
- simonra 10mo agoLook up «Braess's paradox», more throughput when removing capacity is long established (century +) in systems with simplistic greedy agents like humans
- CarVac 10mo agoRoad throughput doesn't solve congestion when road throughput isn't the issue. They are trying to widen the NJ Turnpike but the congestion isn't because 6 lanes aren't enough, the congestion is because the three Hudson crossings into Manhattan cannot ingest 6 lanes worth of traffic.
- array_key_first 10mo agoEach additional lane has less and less impact because of lane switching. Ultimately, you can still only enter or exit on the left or right, regardless of if you have 100 lanes. And having people move across 100 lanes to exit is much slower than moving across one or two.
