Coverage analysis
What 60 minutes covers in Boston.
Boston's road network predates the grid era, and drive-times here are notoriously hard to model with default assumptions. The Charles River, the harbor, and a tangle of pre-revolutionary streets make isochrones unusually irregular even with modern routing engines.
At 60 minutes, the Boston isochrone captures the metro-wide reach — a regional footprint where destination-category businesses draw from a wide geographic spread. Unlike a 400–1,200 km² circle, the real road-network polygon follows Boston'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 60 minutes: Distribution center, regional franchise territory, e-commerce fulfillment, hospital system, workforce housing. The 60-minute isochrone is the standard input for regional territory design and logistics network planning.
The city-level population of 675,647 and a median household income of $81,290 give a sense of Boston'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.
