Humans may choose a route to their destination on a different basis than the 'shortest'
It is known that the shortest distance between two points is a straight line, but in reality there is no straight road connecting the current location and the destination, so choose a route that avoids buildings and impassable places. Will be. Studies have shown that humans may have other guidelines in this route selection that are not the 'shortest path.'

A research team led by Christian Bongiorno of the Massachusetts Institute of Technology conducted a survey based on a dataset of more than 550,000 gait routes collected from more than 14,000 pedestrians over the course of a year. As a result, many pedestrians choose the 'pointiest path,' which the team describes as the 'pointiest path,' instead of choosing the shortest path. It turned out that there was.
Below is a map showing the shortest path (blue) and pedestrian path (red) that were actually confirmed. It has been shown that pedestrians do not always follow the shortest path from the house mark (current location) to the flag mark (destination). In addition, the distance difference from the shortest route increased as the distance to the destination increased.
In addition, we know that humans 'follow an asymmetric path' when going back and forth between two different points. The map showing this is shown below, showing that the route from the house mark to the flag mark (blue) and the route from the flag mark to the house mark (red) are different. I am.
Bongiorno et al. Call such route selection 'vector-based route selection'. It is difficult for humans to grasp the shortest path perfectly, unlike a computer that uses an algorithm to find the shortest path to the destination. 'For humans, choosing a route in terms of reference points, landmarks, and angles is a very natural way to understand space,' said Bongiorno and colleagues.
It is said that such route selection can be seen in animals other than humans, and Bongiorno et al. It may have evolved in this way to do so. '
'As smartphones connect humans to artificial intelligence, it's increasingly important to understand how the computational mechanisms our brains relate to computer computational mechanisms,' said Carlo Ratty, who participated in the study. It will be. '
