Coverage analysis
What 45 minutes covers in Baton Rouge.
River-bound and highway-split, Baton Rouge isochrones stretch aggressively east along I-12 while the Mississippi River hard-stops westward expansion within 3 miles of downtown.
At 45 minutes, the Baton Rouge 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 Baton Rouge'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 227,470 and a median household income of $52,000 give a sense of Baton Rouge'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.
