Circuity is defined as the average ratio of the length of the trip to the crows' flight (or direct) distance between the end points of the trips starting at an Origin Zone and ending at a Destination Zone. A low circuity trip would be one that takes the most direct path between your Origin and Destination Zone. A high circuity trip would be one that takes an indirect route, between your Origin and Destination zone. Think of an Uber or delivery truck creating a highly circuitous trip as they make pickups and dropoffs. So if trip circuity is "2," think of it as any trip that is 2x as long in distance compared to the "as the crow flies" distance between the Origin and Destination Zones.
