Figure 3From: Estimating spatial accessibility to facilities on the regional scale: an extended commuting-based interaction potential modelDistribution of probabilities for spatial interaction at a given distance. These graphs show cumulated per cent of trips that are greater than a given distance for hyper/supermarkets (left) and grocery stores (right). Data for bakeries are not shown. Plotted values can also be seen as the probability for interaction at a given distance. It allowed us to have an idea of the type of distance decay function.Back to article page
