      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.

      How's the capacity infinite in theory? it's constrained by the length and speed of cars no? the theoretical max is the cars right after each other going full speed (unless i'm misunderstanding the problem)

      It's not infinite. You're right. The capacity is bounded by the maximum speed of cars and their length relative to the length of the road. That said, we're so far from that capacity, it's basically infinite.

      I'm unsure how to calculate the true capacity of the road, but: Suppose 1,000,000 cars needed to go 10 miles from point A to point B. Max car speed is 100 mph. Car length is 15 feet. It takes 6 minutes to go 10 miles at 100 mph. Every 10th of a second, a car onramps...

      Loading seems to be taking a while.

      Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
