How slow does traffic need to be going on the highway in order to justify taking surface streets?
All right Mathletes, I’m looking for pseudo-science here. Now that I have a rush-hour commute, I’m often sitting on the highway contemplating whether I should jog off and take the lights.
The surface street has lights about every 3 blocks or so, and they aren’t timed.
