> If you expand a road, there will be greater usage because demand soaks up supply. Only up to a limit, as I mentioned. They won’t keep “soaking up” supply. People are not looking to drive 24/7. They are looking to reach destinations and spend time there. > Of course, you can continue to expand roads. Problem with that idea is that the roads displace other uses of land such as homes and businesses. This seems like a vague argument. Road space displaces other uses marginally. If your population were held equal, then you can build more roads, displace some amount of other uses, and the increased traffic from those displaced wouldn’t be nearly as much as the extra traffic capacity the road provides. If your population increases or usage patterns change, then it is simply “latent” demand that is being met, since there’s an appetite for more travel throughout and increased speeds and all the utility that brings. All of this applies to anything that we can model with supply and demand, including bike lanes.
