Predicting physical distancing on recreational trails during COVID-19

The emergence of Coronavirus 19 led to societal and behavioral changes, including intensified use of many public parks and trails for mental respite and leisure time physical activity. As visitors sought stress-relief in the great outdoors, they also encountered stressful situations as they navigated risk exposure. Recommendations to physically distance between parties was a key component to reduce risk, but compliance is unknown in the outdoor arena. This observational study of more than 10 000 trail user encounters documented distancing and enabled predictive analysis that revealed wider trails, smaller groups and signage led to greater distancing compliance. Managers and planners can integrate these findings immediately and in consideration of future trail designs to minimize risk exposure.Management implications: Select site features increase odds of distancing compliance and can inform management decisions and designs immediately and in addressing future use surges: wider trails, unpaved surfaces, and COVID-19 signage.As distancing compliance waned with time but signage increased compliance, innovative and dynamic signs may sustain compliance and multi-media communications should be considered. Both activity size and group type influence distancing so considering group size recommendations and activity separation are in order.

Cases and context: mask-related behaviors among U.S. trail visitors during the COVID-19 pandemic. (Special Issue: Covid-19 and outdoor recreation.)

The challenge of simultaneously providing outdoor recreation opportunities while protecting the public from SARS-CoV-2 virus and COVID-19 transmission, as well as future pandemics, remains foremost on managers' minds. Safe spaces and cultures are paramount for managers and visitors alike. Recommended protective measures against COVID-19 included physically distancing 1.8 m (six-feet) between parties and mask-wearing when distancing is not possible. Adoption of these protective measures is relatively unknown but essential to inform recreation management and planning through future health crises. Such adoption is likely influenced by both the pandemic context and site context, particularly related to visitor density. An observational study assessed mask-wearing behaviors among trail walkers on multiple trails in the United States from November 2020 through May 2021. Trained observers identified if walking groups were prepared to mask or had masks correctly worn as well as if encounters were compliant with the 1.8 m recommendations. Data collected across seven U.S. states enabled comparisons of mask-related behaviors across sites as well as considerations to: the influence of the pandemic context in terms of cases and vaccination rates, mask mandates, and trail density. Results from nearly 3000 encounters revealed significant variance in visible masks, low compliance of mask-wearing in encounters less than 1.8 m, significant influence of both COVID-19 cases and vaccination rates on mask wearing at half the sites, and no impact of state-level mask mandates when controlling for cases and vaccinations. Integrating public health data can inform predictions of compliant behaviors, or lack thereof, and needs exist to advance a safety culture.

COVID-19 compliance among urban trail users: behavioral insights and environmental implications. (Special Issue: Covid-19 and outdoor recreation.)

Public green spaces provide physical and mental respite, which have become essential and elevated services during the COVID-19 pandemic. As visitation to public parks and recreation areas increased during the pandemic, the challenge of maintaining visitor safety and protecting environmental resources was exacerbated. A key visitor safety practice during the COVID-19 onset was maintaining a physical distance of six feet (1.8 m) between groups. A novel data set documented and compared physical distancing compliance and off-trail behavior on multiple-use trails across multiple states and within select U.S. communities, attending to the impact of select environmental factors. Nearly 6000 observations revealed physical distancing compliance varied and the environmental factors of trail width, density, and signage influenced its variability. Similarly, off-trail movement was related to trail width and density. Clearly the environment matters as people negotiate the 'new normal' of physical distancing during physical activity and outdoor recreation participation. Given the ongoing COVID-19 pandemic and likelihood of future health crises, this project provides important information and insight for trail and other public green space management, monitoring, and modelling moving forward.

Implications of COVID-19 mitigation policies on recreational trail users: exploring antecedents to physical distancing on trails across the rural-urban continuum. (Special Issue: Space, place, and COVID-19.)

The COVID-19 pandemic and subsequent travel restrictions led to a worldwide increase in greenspace use. The U.S. Centers for Disease Control and Prevention encouraged policies including physical distancing and COVID-related signage. However, the extent to which these policies influenced behavior is unknown. To fill this gap, we report on a 2020 observational study at 14 trails across six U.S. states framed within a social-ecological model. Behavioral observations of 8,093 groups assessed compliance rates with infection-mitigation behaviors. Additionally, we noted the presence of COVID-related signs, the days between the observation and stay-at-home order start date, the setting (i.e., urban, suburban, and wildland-urban interface), and correlation with the distance between groups that encountered one another. Group size, presence of signage, days since stay-at-home order implementation, and trail setting significantly correlated with physical distancing compliance, while controlling for trail design and encounter rate. Hence, both policy and setting appear to influence COVID-19 mitigation behavior.
