In ancient Rome, there was a law that no wheeled vehicles could be in the streets between the hours of sunrise and sunset. That way pedestrians, and maybe people on horseback, had the streets to themselves in the daytime. But you have to figure that it was hard to sleep at night in the city, since wheels were either wood or shod with metal, and the streets were cobblestone, and all the wheeled traffic ran from sunset to sunrise.
