Active Living Research

This study evaluates how household interactions affect walking and biking to school. The cross-sectional research design uses a representative sample of trips to school by US youth (n = 8231) to test how parental employment status and commute patterns affect non-motorized travel. Results from a binary logit model show that young children (5-14) with mothers who commute to work in the morning are less likely to walk or bike to school after controlling for individual, household, and neighborhood factors. Policymakers may therefore want to create programs that allow parents to share chaperoning responsibilities for the school trip to address parental time constraints.

The standard Hansen measure of accessibility is extended to provide a use-based measure of accessibility reflecting the elasticity of use with respect to the level of provision of facilities. This is further extended to provide a measure of accessibility to linear features, such as trails (as opposed to features at point locations such as parks and libraries). Results from a survey on the use of urban trails in Indianapolis, Indiana are used to test the ability of this accessibility measure to predict trail use. The use-based measure of accessibility to linear features provides better predictions of use and more consistent estimates of the effects of distance and level of facility provision on trail use.

In 1969, 48% of students walked or biked to school. By 2001, that proportion had fallen to 15%. Increasing children's active travel to school is important for a variety of reasons, including the rising rates of childhood obesity and increasing fuel costs. Recent studies indicate that elements of the built environment affect the amount of time people engage in physical activity. This study evaluates two indicators of the urban form as measures of walkability potential: street connectivity and residential density around elementary schools in Pasco and Hillsborough counties in Florida. By means of controlling for school age on the basis of the growth management legislation history in Florida, four growth eras are compared. Pedestrian sheds of 1/2- and 1-mi radii around school points are used as study areas. These indicators offer insight into the evolution of the urban form around elementary schools and its implications for students' ability to walk to school. Preliminary findings suggest that walkability indicators in the vicinity of elementary schools built before 1950 exhibited high levels of street connectivity and residential density. These values declined consistently until stricter school planning legislation was enacted, when values started to increase and sometimes approached pre-1950 levels. This pattern is stronger, however, in Hillsborough County.

BACKGROUND: Somerville, Massachusetts, an ethnically diverse, urban community northwest of Boston, presents opportunities and challenges for active living. With a dense street grid, well-maintained sidewalks, neighborhood parks, and existing Community Path, Somerville is very walkable. However, two major surface arteries traverse and bisect neighborhoods, creating pedestrian safety and environmental justice issues. INTERVENTION: Major goals included promoting increased collaboration and communication among existing active-living efforts; managing the Community Path extension project; encouraging Portuguese-speaking adults to incorporate daily physical activity; leveraging existing urban planning work to establish secure, attractive walking/biking corridors; and embedding active-living messages in everyday life. RESULTS: The Somerville Active Living by Design Partnership (ALbD) successfully created a robust task force that was integrated with citywide active-living efforts, secured resources to increase infrastructure and support for active living, including city-level coordinator positions, and changed decision-making practices that led to incorporation of pedestrian and bicycle transportation priorities into city planning and that influenced the extension of the Community Path. LESSONS LEARNED: Partnerships must employ sustainability planning early on, utilize skilled facilitative leaders to manage leadership transitions, and engage new partners. Identifying, cultivating, and celebrating champions, especially those with political power, are critical. Working closely with research partners leads to rich data sources for planning and evaluation. Changing the built environment is difficult; working toward smaller wins is realistic and achievable. CONCLUSIONS: The synergy of ALbD and other community interventions created a foundation for short-term successes and accelerated political-cultural changes already underway with respect to active living.
