Coverage analysis
What 5 minutes covers in Atlanta.
Atlanta has one of the worst peak-hour traffic asymmetries in the United States, and the metro's signature drive-time challenge is the Perimeter (I-285). Sites inside the Perimeter (ITP) and outside (OTP) behave like fundamentally different markets despite physical proximity.
At 5 minutes, the Atlanta isochrone captures the hyperlocal footprint — the area where customers make routine, repeat visits without deliberate trip planning. Unlike a 2–4 km² in a suburban grid; far less in a grid with barriers circle, the real road-network polygon follows Atlanta's actual highway corridors, accounts for bridge and interchange chokepoints, and respects the natural and built barriers that force drivers to detour.
Best-fit categories at 5 minutes: QSR, coffee, convenience, pharmacy, urgent care, car wash, gas station. The 5-minute isochrone is the standard input for footprint mapping and proximity-marketing radius decisions.
The city-level population of 498,715 and a median household income of $64,179 give a sense of Atlanta's economic density, but the figure that matters for site selection is the population inside the polygon — not the city as a whole. That number shifts dramatically depending on whether you're drawing from a high-density urban core or a lower-density suburban corridor. Use the tool above to set your actual candidate location, then generate the isochrone to see the real catchment.
