Primary Versus Secondary Trade Areas

Primary zones supply the majority of routine visits—often five to ten minutes by car or a walkable radius in urban cores. Secondary zones add occasional guests from special trips or events.

Drive-Time Isochrones and Barriers

Rivers, Highways, and Retail Gates

GIS tools draw isochrones respecting one-way grids, highway dividers, and gated communities that block through traffic. A straight-line mile lies; drive time tells whether office workers will cross the river for lunch. Barriers shrink effective trade areas even when demographics look dense on paper.

Delivery Trade Area Versus Dine-In

Courier Reliability Zones

Delivery polygons may extend farther than dine-in when couriers are plentiful, but food quality sets the real limit. Define delivery trade area separately with max minutes out the door plus transit.
