Coverage analysis
What 45 minutes on foot covers in Houston.
Houston has no zoning, three concentric loop highways (610, Beltway 8, Grand Parkway), and continues to sprawl in every direction. Drive-time isochrones here can cover staggering land areas, which makes household-density weighting more important than polygon size.
At 45 minutes on foot, the Houston walk-time isochrone captures the urban mobility boundary — a wider pedestrian catchment used for destination walking, accessibility auditing, and urban mobility analysis. Unlike a simple ≈ 3.5 km radius circle, the real pedestrian-network polygon follows Houston's actual street grid, accounts for crossings, parks, and dedicated walk paths, and contracts sharply around freeways, rail corridors, and waterways that break pedestrian continuity.
Walk-shed area at 45 minutes: ≈ 7–15 km². The 45-minute isochrone is the standard input for urban accessibility auditing and transit-gap identification.
The city-level population of 2,304,580 and a median household income of $57,791 give a sense of Houston's density, but the figure that matters for walkable-retail siting is the population inside the pedestrian polygon — not the city as a whole. That number shifts dramatically depending on whether you're anchored in a high-density urban core or a lower-density neighbourhood where blocks are long and crossings are scarce. Use the tool above to set your actual candidate address, then generate the isochrone to see the real walk shed.
