Coverage analysis
What 45 minutes covers in Pittsburgh.
Three-river convergence and Allegheny ridges create highly fragmented isochrones where bridge crossings and tunnels add minutes that inflate apparent distance.
At 45 minutes, the Pittsburgh isochrone captures the extended regional draw — a regional footprint where destination-category businesses draw from a wide geographic spread. Unlike a 200–600 km² circle, the real road-network polygon follows Pittsburgh'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 45 minutes: Regional mall anchor, hospital, specialty medical, premium auto, luxury retail, cinema. The 45-minute isochrone is the standard input for regional territory design and logistics network planning.
The city-level population of 303,000 and a median household income of $55,000 give a sense of Pittsburgh'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.
