When people leave matters as much as how far they go. Rush-hour traffic shrinks how much ground a 20-minute trip covers, so a trade area drawn as a simple circle often takes in neighborhoods that customers or staff would never drive from and misses others that are an easy trip. A drive-time zone, also called an isochrone, outlines every place within a set number of minutes of an address, which makes it the more honest way to size a store's catchment, a hiring area or the commute from a new home.
