> If you’re not convinced, just look at the empty highways at night. This part threw me off because it seemed to contradict your argument. But I’ll try to get past that. What your saying here is that demand for roads will always be fixed at X cars per minute between 7am to 9am, for example. So if a road between a city and a suburb was built to handle 1.5 * X cars per minute, then there would be no traffic jam between the two places from 7am to 9am. But that’s assuming this new capacity won’t encourage city dwellers to move out into the suburb especially if the latter is cheaper, has more access to greenery, etc. In addition, there could be commuters who, realizing that said road now has greater capacity, will start commuting within the 8am-9am period instead of earlier/later because it’s more convenient. In both cases, wouldn’t that, in effect, be a case of induced demand?
