Walkability Research
Decades of peer-reviewed research established that walkability shapes home values, lending risk, health, and how much people walk. SafeStreets turns that evidence into an open, address-level walkability score, computed with a citable methodology (DOI 10.5281/zenodo.20506270).
Home values and the walkability premium
Does walkability raise home values?
Yes — walkability commands a measurable price premium. Across 15 major US housing markets, a one-point increase in Walk Score was associated with roughly $700 to $3,000 in higher home values (Cortright 2009); in commercial real estate, more walkable properties carried significantly higher values and net operating income (Pivo & Fisher 2010); and walkability has been tied to fewer foreclosures and lower crime alongside higher values (Gilderbloom, Riggs & Meares 2015).

Mortgage default and lending risk
Do walkable locations have lower mortgage and lending risk?
Yes — more walkable, location-efficient places carry lower lending risk. Higher walkability has been linked to lower residential mortgage default rates (Rauterkus, Thrall & Hangen 2010), and for securitized commercial mortgages, sustainable and walkable property features predict lower default risk (Pivo & An 2015, 2016). This is the evidence base for treating walkability as an underwriting and portfolio-risk signal.

Validation of walkability scores
Are algorithmic walkability scores actually accurate?
Yes — peer-reviewed studies validate Walk Score-style measures against ground-truth amenity access and observed travel behavior across multiple US metros (Duncan et al. 2011; Carr, Dunsiger & Marcus 2010), and against how different households respond to their neighborhood (Manaugh & El-Geneidy 2011). An automated, address-level walkability score is a defensible proxy for real-world walkable access — which is what SafeStreets computes, with the method published openly.

Health, physical activity, and travel behavior
Does living somewhere walkable affect health and how much people walk?
Yes — walkable built environments are tied to more physical activity and better outcomes. A landmark meta-analysis confirms that neighborhood density, diversity, and design shape how much people walk and drive (Ewing & Cervero 2010); neighborhood walkability correlates with walking and cycling for transport (Saelens, Sallis & Frank 2003) and with measured quality of life (Rogers et al. 2010).
