Context/Purpose. With the motivation to evaluate the suitability of a urban environment for pedestrian mobility, we revisit walkability scores from the scientific literature whose one of the most representative figure is the Walk Score, which is also commercially exploited through an eponymous website. Methods. This study refines the purpose of the foundations of walkability scores as a “pedestrian level of accessibility” score and mobilizes works on accessibility to simplify the computations of the score. The parameter “importance of an amenity” gains a more generic estimation method. Lastly, the scoring is proposed for different trip categories before being aggregated into a global score. Results. We obtain a new scoring, which we apply to a small town with a simple urban layout for illustration purposes before computing scores for a larger and more diverse area. The scores allow us to identify different urban fabrics associated with different opportunities within walking distance. Conclusions. In the end, we provided walkability scores with a more scalable, explainable and readable methodology which led to improve their usefulness.
