SAFEWAY: An explainable context-aware recommender system for safe routes

. This paper presents SAFEWAY, a case-based recommender system to propose and explain the safest route between two points taking the user context into account. The novelty of this work is twofold. First, it considers safety as the main goal to optimize during the route calculation, and includes dynamic restrictions from the user context, like geographical, temporal, weather, and past accidents in that route. Sec-ondly, it presents an approach to increase the acceptance of the recommendations by means of graphical explanations about the route safety. The paper describes a version of the SAFEWAY system that works with a memory of cases obtained from the Road Safety dataset that includes road accidents in GB since 1979.
