This study tested whether neighborhood greenways (NG) policy interventions can promote physical activity, such as walking and cycling, and also achieve traffic calming in the Portland, Oregon. Propensity score matching and IPW methods were used to estimate effects. The results showed that, regardless of the analysis method, the introduction of NG was effective in increasing "walking frequency" among physical activities. On the one hand, UGB residents who experienced a decrease in traffic showed effects related to traffic calming, but felt that the bicycling environment was unsafe. On the other hand, for residents living in areas where NG was implemented, the effect was shown in terms of perceived car speeds.
