A multiple cyclic-route generation method for strolling based on point-of-interests

With the spread of map applications, route generation has become a familiar function. Most of route generation methods search a rapidly movable route to a destination, but more enjoyable route generation is recently focused on. Particularly, cyclic-route generation for strolling requires to suggest to a user more than one route passing through several POIs (Point-of-Interests), to satisfy the user's preferences as much as possible. In this paper, we propose a multiple cyclic-route generation method for strolling based on POIs. Firstly, our proposed method finds out a set of reference points based on the route length constraint. Secondly, we search a non-cyclic route from one reference point to the next one and finally generate a cyclic route by connecting these non-cyclic routes. Compared with previous methods, our proposed method generates a cyclic route closer to the route length constraint, reduces the number of the same points passing through by more than 80%, and increases the number of passing through POIs to approximately 1.24 times.
