Do you think the system of roads in the assyrian empire worked well? explain?

I would say they did work well. The reason is that at the time, very few civilizations (if any at all) maintained a big road network that kept the civilization well connected and allowed for "fast" transport of information. This wa different in the Assyrian empire as local governors were required to maintain roads and road stations at points of strategic interest which enabled, as a consequence of better infrastructure, faster communication as well.
