What term describes the method used to enhance points for more distant amenities when calculating a walk score?

The term that describes the method used to enhance points for more distant amenities when calculating a walk score is known as a decay function. This concept is rooted in the idea that while proximity to amenities is valuable for walking accessibility, the effect of that proximity diminishes as the distance increases. A decay function applies a mathematical model that reduces the impact of amenities based on how far away they are from a particular location, reflecting the reality that people are more likely to take advantage of nearby amenities than those that are farther away.

This method is important in accurate walk score calculations because it allows planners and developers to assess how access to amenities can influence walking behaviors and overall community health, thereby encouraging thoughtful urban design that prioritizes accessibility.
