Coverage analysis
What 15 minutes covers in Fort Worth.
Flat prairie enables wide, nearly circular isochrones, with DFW Airport creating a notable northeastern dead zone and Trinity River floodplain providing minor downtown constraints.
At 15 minutes, the Fort Worth isochrone captures the standard trade area — a zone where trips are planned but customers are willing to cross neighborhood boundaries. Unlike a 30–80 km² in typical US metros; the range varies 3× depending on road density and barriers circle, the real road-network polygon follows Fort Worth'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 15 minutes: Casual dining, specialty retail, auto service, full-service salon, pet supply. The 15-minute isochrone is the standard input for franchise disclosure documents and protected-territory negotiations.
The city-level population of 935,000 and a median household income of $63,000 give a sense of Fort Worth'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.
