Air Pollution and Outdoor Recreation on Urban Trails: A Case Study of the Elizabeth River Trail, Norfolk

Poor air quality represents a significant health risk for individuals engaging in recreation activities outdoors in urban parks and trails. This study investigated temporal variability in particulate matter (PM) exposure along an urban waterfront trail. We also used recreation choice frameworks to examine the effects of visitors’ perceptions of air quality (AQ) and health benefits on trail use. Average air quality during the collection period was “good” (PM10) to “moderate” (PM2.5). We found that PM density was significantly higher (p < 0.001), though still in the “moderate” range, at 7–9 a.m., 11 a.m.–1 p.m., and 3–5 p.m., and on weekends. Visitors’ self-reported perceptions of health outcomes, but not air quality, significantly predicted trail use. Results suggest that these experiential factors may affect recreational choices depending on other factors, such as salience. Further research is merited to determine how experiential factors can be integrated with other theories of motivation to understand recreational decision-making.

Support for and Behavioral Responses to Tolls

This chapter analyzes the experiences with tolling in the Hampton Roads region of Southeastern Virginia to better understand residents' and drivers' support for tolls and behavioral responses to tolls. The Hampton Roads region, with its population of 1.7 million and extensive network of highways, roads, bridges, and tunnels, has a long history of toll facilities that date back to the 1920s. The most recent tunnel tolls, associated with the Elizabeth River Crossing Project and introduced in February 2014, are the focus of this chapter. This chapter analyzes two sets of survey data to provide insights that have implications for policies regarding tolling: (1) The Life in Hampton Roads Surveys which includes questions about support for tolls and toll avoidance behaviors; and (2) two surveys (pre- and post- toll implementation) commissioned by the regional transportation planning organization.
