Which score is NOT included in the three levels of walkability scores?

The score that is typically not included in the three levels of walkability scores is 100. Walkability scores are often categorized into different ranges to assess how conducive an area is to walking. Generally, these scores focus on thresholds around the mid-range to high-range scores, such as 50, 70, and 90, which indicate varying degrees of walkability. A score of 100 suggests a level of walkability that approaches perfection, which is often unrealistic for most urban or suburban environments. Therefore, while 50, 70, and 90 represent measurable and achievable walkability levels, a score of 100 stands out as an outlier, not fitting within the standard scoring framework used to evaluate walkability effectively.
