I 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


If 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.


Removing parts of the city to add more lanes will also help decreasing demand - it's a win-win!
