Physical Activity: Park, Trail, and Greenway Infrastructure Interventions when Implemented Alone
Summary of CPSTF Finding
The Community Preventive Services Task Force (CPSTF) finds insufficient evidence to determine whether park, trail, and greenway infrastructure improvements increase physical activity when they are implemented without additional interventions. Evidence was considered insufficient because changes in physical activity were inconsistent. Studies did find meaningful increases in the number of people using parks, trails, and greenways following infrastructure improvements. CPSTF finds, however, that the economic benefits exceed the cost for these interventions.
CPSTF recommends park, trail, and greenway infrastructure interventions when combined with additional interventions.
Intervention
- Parks designated public areas that often combine greenery with paths, facilities for physical activity and recreation, and places for relaxation and social interaction
- Trails and Greenways routes for walking, hiking, or cycling in urban, suburban, or rural areas (e.g., “rails to trails” conversion projects). These may involve street conversions that provide opportunities for walking and cycling (most often in urban areas).

Audio Clip
We are affected by the world around us, and evidence shows that combined approaches to enhance the built environment can increase physical activity. Drs. Shiriki Kumanyika and David Hopkins and Mr. Chris Kochtitzky talk with CDC’s Dr. John Anderton about the systematic review evidence and how the CPSTF recommendation for combined built environment approaches can be implemented in communities.

About The Systematic Review
- Studies included in a broader systematic review published in 2019 (Hunter et al., 12 studies, search period through August 2016)
- Studies identified in an update search (5 studies, search period August 2016 July 2020)
The systematic review was conducted on behalf of CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to physical activity and the built environment.
Summary of Results
The systematic review included 17 studies that evaluated infrastructure improvements when used alone. Physical activity outcomes reported in the included studies could not be combined to provide summary effect estimates.
- Ten studies examined changes in moderate-to-vigorous physical activity in the park, trail, or greenway and observed inconsistent effects.
- Five studies evaluated changes in total physical activity and observed inconsistent effects.
- Six studies examined other measures of physical activity and observed inconsistent effects.
- Nine studies examined changes in use of the park, trail, or greenway (regardless of the level of physical activity) and observed a median increase of 32.1%.
Summary of Economic Evidence
A systematic review of economic evidence from a societal perspective shows the economic benefits exceed the cost for park, trail, and greenway infrastructure interventions.
The review included 8 studies (search period through March 2022) that evaluated the infrastructure component of interventions. The review team did not find any studies that evaluated infrastructure plus additional interventions to increase community engagement, public awareness, programming, or access. Monetary values are reported in 2021 U.S. dollars.
- The median one-time capital cost was: $8,679,850 (7 studies).
- The median annual maintenance cost was: $34,570 (7 studies).
- The median annual benefit was: $994,000 (7 studies).
- The cost per disability-adjusted life year (DALY) averted was: $23,254 (1 study).
- The median benefit to cost ratio was: 3.1 (7 studies).
Applicability
Evidence Gaps
- Do these interventions increase physical activity?
- Which characteristics of infrastructure improvements are effective in increasing physical activity and use?
- Are these interventions effective for improving other health and health-related outcomes including the following?
- Fitness
- Mental health including measures of anxiety, depression, and well-being
- Perceptions of social cohesion and connectiveness
- Injuries
- Quality of life
- How effective are these interventions across different communities and populations?
- How effective are park, trail, and greenway infrastructure improvements alone in reducing perceptions of crime and improving perceptions of safety among members of the community?
- Which interventions, or combinations of interventions, are most effective in addressing barriers to use of parks, trails, and greenways among the following populations?
- Communities with lower incomes
- Older adults
- People with disabilities
- What is the cost-effectiveness of park, trail, and greenway interventions?
- What are the economic effects of neighborhood displacement on residents from historically disadvantaged racial and ethnic populations and populations with lower incomes?
Study Characteristics
- Study designs included randomized controlled trials (1 study), other designs with a concurrent comparison group (9 studies), and before-after without control (7 studies).
- Park infrastructure improvements noted in the studies included a new park (1 study), added new structures (3 studies), renovations to existing structures (7 studies), and a combination of new construction and renovations (2 studies).
- Trail and greenway infrastructure improvements included a new route (1 study) and extensions to existing routes (2 studies).

Analytic Framework
Effectiveness Review
- Logic Model – Effectiveness Review [PDF – 153 KB]
- Text Description – Effectiveness Review [PDF – 73 KB]
When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.
Economic Review
The economic review team develops an analytic framework to align economic outcomes with each stage of the effectiveness review analytic framework. It informs the economic research questions and may be used to summarize the evidence for intervention cost, economic benefit, cost-effectiveness, and cost-benefit.

Search Strategies
Effectiveness Review
The CPSTF recommendation is based on a systematic review of 38 studies (published through July 2020). The review combined 26 studies of park, trail, or greenway interventions identified from a published systematic review (Hunter et al. 2019; search period through August 2016) with 12 studies identified in an updated search that used the same search terms (search period August 2016 to July 2020).
Hunter et al. (2019) included 38 studies in their review. The Community Guide review team assessed each study based on community guide methods and identified 26 eligible studies for this review. The Community Guide updated search for evidence used a search strategy adapted from Hunter et al. 2019.
Databases searched for this review included Medline, PsycINFO, CAB Abstracts, Scopus, Cochrane, Greenfiles, and Agricultural & Environmental Science Dissertations Environmental Science Collection.

Economic Review
In March 2022, a research librarian used terms adapted from Hunter et al. (2019) to search the following databases: Medline, CAB Abstracts (OVID), PsycINFO (OVID), Scopus, Cochrane Library, GreenFILE (EBSCO), EconLit (EBSCO), Agricultural & Environmental Science collection (ProQuest), CRD York/NHS EED, CRD York/DARE, NTIS. The search covered the period from database inception through March 2022.
The search was limited to high income countries as defined by the World Bank. Search terms and strategies were adjusted for each database, based on controlled and uncontrolled vocabularies and software. The review team also screened reference lists of included studies and consulted subject matter experts about additional studies.

Considerations for Implementation
Equitable park access can be defined as the just and fair quantity, proximity, and connections to quality parks, as well as programs that are safe, inclusive, culturally relevant and welcoming to everyone (National Recreation and Park Association 2021). To achieve this, health equity principles can be used to guide park priorities and investments in ways that involve and sustainably benefit communities (Cole et al. 2019).
Implementation guidance incorporating equity considerations is available from several organizations:
The National Recreation and Park Association advocates for parks and recreation throughout communities with emphasis on health and wellness, equity, and conservation.
The Trust for Public Land works to create recreational spaces and provides a tool kit for collaborating with communities in the development of parks.
The Safe Routes Partnership provides fact sheets, toolkits, and infographics to help communities implement active travel to parks.
The Rails to Trails Conservancy provides implementation and equity guidance relevant to trails and greenways.
The City Parks Alliance is a network of leaders in urban parks and recreation that shares research and tools, including those promoting health equity and environmental practices.
Healthy Places by Design works to advance community-led action across the country. They provide reports and action guides for local government leaders and organizations as well as information about their Community Action model.
The Prevention Institute has developed a toolkit for community-based organizations, including a park equity toolkit tip sheet and a webinar series.
Park, trail, and greenway interventions may be linked or coordinated with other elements of the built environment including two CPSTF-recommended approaches to increase physical activity:
- Built Environment Approaches Combining Transportation System Interventions with Land Use and Environmental Design (2016)
- Interventions to Increase Active Travel to School (2018)
Greening-without-Gentrification [PDF – 2.6 MB] proposes strategies to prevent or reduce the possible harms of gentrification or displacement of current residents following the establishment of large parks, trails, or greenways.
