In recent years, the number of vulnerable shopping people who have difficulty accessing fresh food stores has increased. This problem is called the food dessert problem. Mobile supermarkets are one of the ways to solve the food dessert problem. In this study, we investigate mobile supermarkets in Hitachi City, Ibaraki Prefecture. Next, we analyze the food desert area using metabolic equivalent distance considering road gradient. Then, we find the efficient traveling route of the mobile supermarket using a mathematical model. As a result, it became clear that the total travel distance can be reduced by about 30 km in one week. The results of this research will greatly contribute to evaluate for sustainability of the mobile supermarket business.
