Observational data were collected by community observers trained in systematic direct observation techniques along three greenways; the Conner Creek Greenway (Detroit's Eastside), Mexicantown-Corktown Greenway (Southwest Detroit), and the Lyndon Greenway (Northwest Detroit). Data were collected for six months in each year (May-October) for three years (2006-2008). In each month, observers were stationed at designated points along the greenway at four 10-minute intervals each day (early morning, noon, mid afternoon and early evening), with data collected on two weekend days and two weekdays during a one week period in each data collection month. Data collection instruments were modified versions of the SO-PARC instrument (McKenzie et al 2006), modified for use along a greenway rather than for a larger park area.

To assure systematic observations, we assessed inter-rater reliability between each observer and a gold standard staff member for 25 pedestrian observations and 10 station observations. To commence observations, each observer was required to have at least 80% agreement (Cohen's Kappa > .8) at the beginning of each year of observation, and was assessed again during the study period (Cohen 1960).

In addition, once each month an observer walked the entire length of the greenway to collect observational data on the characteristics of the Greenway itself as it changed over time. This data collection form modified tools and measures that were part of the Robert Wood Johnson Foundation Active Living Research Program, including Systematic Pedestrian and Cycling Environment (SPACES) Instrument, Pedestrian Environment Data Scan (PEDS), Path Environment Audit Tool (PEAT), SOPARC: System for Observing Play and Recreation in Communities, in addition to the HEP Neighborhood Observational Checklist (NOC). The form focused on built environment characteristics of the Greenway itself and some characteristics of the social environment (e.g., police presence, presence of other pedestrians).

A composite database links data from the observed pedestrian activity form and the observed characteristics of the Greenway, enabling analysis of relationships between characteristics of the Greenway and pedestrian use over time.
