A Route Evaluation Method Considering the Subjective Evaluation on Walkability, Safety, and Pleasantness by Elderly Pedestrians
To improve the quality of life (QOL) of elderly people, we propose a route planning method considering the subjective evaluation on walkability, safety, and pleasantness of the users. By using this method, it is possible to plan a route with lower physical load, higher safety, and more enjoyable for each elderly user. To quantify their preferences, the acceptable time delay is used for the cost functions. In this study, we confirmed that the factors can take into consideration the mental and physical situation of the user and acquired the quantitative cost functions for these factors. The cost functions were constructed based on the subjective evaluation data. The basic validity of the method was confirmed by a subjective evaluation experiment.
