It is actually possible for an additional road to increase the travel time for each driver, without any new cars added, and with everybody acting rationally! Braess's paradox (https://en.wikipedia.org/wiki/Braess%27s_paradox https://en.wikipedia.org/wiki/Braess%27s_paradox). It has been observed in practice.
- lazyjones 8y agoThat's a whole can of bogus science you opened there. The Wikipedia example is particularly funny, since it looks at a case where a new road is suddenly added and all drivers currently on the road switch to it momentarily because at one single moment in time it looks beneficial (but isn't). In reality, people don't change their routes based on new roads added during their trips and even if they did, they'd quickly learn a new overall more efficient route instead of what this bogus example suggests.
