Assessing urban walking trail use and changes in the trail environment using systematic observational protocols

► Modified two systematic observation protocols for use in underserved communities. ► Modified protocols assessed use of a walking trail and their physical features. ► Reliability for measuring trail use was found to be high (ICC=.98, p<.01). ► Reliability for measuring trail features was κ=.77-1.00; ICC=.34−1.00. ► Modified protocols were shown to be reliable for use in underserved communities.
