Effectiveness of a Point-of-Decision Prompt to Encourage Physical Distancing on Greenways and Rail-Trails During the COVID-19 Pandemic

Adherence to public health messaging recommending physical distancing in public outdoor spaces during the early months of the COVID-19 pandemic and strategies to promote physical distancing are currently unknown. This study examined the effectiveness of a point-of-decision prompt to increase physical distancing (maintaining at least 6 ft of distance) on greenways and rail-trails using systematic observation with passive infrared cameras. Results indicate that the intervention did not have a significant effect on interacting groups maintaining physical distance. However, groups maintaining physical distance increased from baseline (72%) to post-intervention (79%) and likelihood of maintaining physical distance at baseline and post-intervention was higher when: passing in the opposite direction compared to passing in the same direction; using 12-foot-wide trails compared to 10-foot-wide trails; and only one person was in each group. These results provide important implications for public health and parks and recreation professionals to promote physical distancing on multi-use trails.
