[DC Comics] How does Batman and Green Arrow protect their entire cities?

They've got allies sure, and they've got the police on their side also but these guys can't fly. They can't move faster than normal, short of a vehicle. So how do they way up what's important and where they should devote their time? 

Gotham at least has shown to have several islands, so does Batman just protect each island on a rotating roster, stopping any crime he sees or hears on a police scanner?

They don't. While Batman is stopping maybe Bane or the Riddler on one side of Gotham, 13 people just got mugged in a straight line leading up to the Killer Croc.

He does a great job relatively, but he is ultimately a human and can only cover but so much area.

This was actually a plot point one a Batman/Superman comic where Bats ended up with Supes' powers. **SPOILER** He hovered above the planet, and marveled on how he could now stop all crime. **END SPOILER**
