Maps of potential accessibility to hyper/supermarkets for residents (left) and commuters (right). These maps make it possible to compare potential accessibility to hyper/supermarkets between residents (left) and commuters (right). Potential accessibility was estimated with an exponential-shaped function and a 19 km span. In the case of commuters, potential accessibility is cumulated in municipalities of both residence and workplace and weighted according to the inverse distance between them and the number of commuters. Class limits are defined according to quantiles.
