Turn Right or Turn Left? Heuristic of A dhering to the Direction of Destination

Copy Summary: It has been found that humans not only tend to avoid the middle routes and prefer the peripheral routes among multiple choices, but also rely on the ‘initial segment strategy’ to select the route. In this paper, we propose a new heuristic which humans apply during route selection: Participants prefer the route whose initial direction lies in the direction of their final destination, while avoiding the route whose initial direction does not. Four maps were designed. The pathways, on different maps, constituted a parallelogram, a rectangle and a square. Pedestrians were instructed to select a route from an origin to a destination on one of the maps. The results confirm the application of the newly proposed heuristic. Other possible factors, such as handedness, route angles and occurrence of turns were excluded. Moreover, the heuristics of deferring decision and relying on initial straightness are not supported.
