The “Street Smart” Walk Score algorithm is based on walking distances from an address to a diverse set of nearby amenities. Certain categories are weighted more heavily than others to reflect destinations associated with more walking trips. In addition, road connectivity metrics such as intersection density and average block length are factored into the score.
Walk Score uses a variety of data sources such as Open Street Map, local business listings, and public data sources such as parks and schools.
The following Walk Score Methodology white paper explains the Walk Score algorithm in detail and provides source code for the algorithm.
The Walk Score methodology was developed with the Walk Score advisory board.
