In this paper, we introduce a pedestrian route optimization model depending on the users preference. The model uses fuzzy sets theory for its capacity to answer subjective and imprecise route choices. The structure of the model is explained and discussed on a pilot study. The proposed Fuzzy Inference System (FIS) model needs to be developed and proved on a detailed case study supported by a database. Yet, it is promising in terms of the effectiveness of fuzzy approach and the simplicity of the application process.
