Library of Trails Benefits

This study analyzes data from Twitter, Flickr, and Instagram to assess visitation at 10 urban and peri-urban Swiss National Forest Inventory sites and evaluates recreational models on a national scale. Social media text was analyzed and a Flickr-based model and Twitter-based model were compared with a pre-existing potential recreation demand (PRD) model to estimate recreational use. Both the Flickr and Twitter models correlated with the existing PRD model; the Instagram model was not evaluated due to data limitations.

This study analyzed changes in visitation on 33 of Ireland’s recreational walking trails between January 2019 and December 2020 using data from infrared sensors and Google Community Mobility Report (GCMR) data. A strong correlation was found between GCMR data and infrared sensors. There was a 6% overall increase in recreational trail usage in Ireland in 2020 compared to 2019.

This study uses mobile data from the analysis platform Streetlight to estimate visitor use in four urban parks and protected areas in Orange County, California. The mobile device methods are compared to other trail counting methods to determine whether mobile device data could be a reliable measure of trailhead visitation counts and spatial distribution of visitor use. Resulting estimates are close to the results from well-established automatic trail counting and GPS-based monitoring methods.

This study estimates the economic impact of the proposed 8.5-mile Pike2Bike trail. More than 80% of Fulton and Bedford County residents expressed support for the proposed Pike2Bike trail and 32% of current and potential business owners indicated they may invest in a new business to support the trail if it were developed. Using surveys, IMPLAN, and results from previous trail studies, three development scenarios were devised with estimated initial investment, visitor level, total visitor spending, and total economic impact. Each scenario resulted in a positive impact on the counties’ economies.

This study summarizes the spending patterns and travel characteristics of respondents cycling on the Murray to the Mountains trail in Australia. A comparison of results to the author’s previous 2003 study on the same trail found that the overall economic contribution per person per trip grew from AUS$203 in 2003 to AUS$483 in 2006, not accounting for inflation.

This report estimates the job creation resulting from the construction of bicycle and pedestrian facilities such as bike paths, trails, sidewalks, and related projects. Based on data from transportation and public works departments in 11 cities with 58 projects, the author estimated that on average, these infrastructure projects create 9 in-state jobs for each $1 million of spending and an additional 3 jobs if out-of-state effects are included. Bicycle-only infrastructure projects contributed to the highest level of job creation.

This study conducts an economic impact analysis of paddling expenditures for both noncommercial and commercial paddlers on rivers in the Nantahala and Pisgah national forests in North Carolina. Results indicated that noncommercial paddler visitors spend an estimated $3.2 million annually across seven rivers.

This study details the expected economic impact of the proposed Firefly Trail in Georgia. The report estimated that the construction of the trail will lead to a one-time increase in total economic output by $32 million, create an additional 158 jobs, and will increase household incomes by $6.9 million at the county level.

The authors conducted a survey in Santa Monica Mountains National Recreation Area in Los Angeles to understand park accessibility and how socio-demographic characteristics affect individuals’ use of the park. They found that the average park user is white, male, middle-aged, has a college education, earns between $50,000-$75,000 per annum, and was born in the United States. They also found that people of color traveled farther to visit the park and were disproportionately represented among first-time visitors.

The authors apply a GIS spatial analysis using social media data to quantify public perspectives of recreational ecosystem services (RESs) or green spaces in Beijing, China. This megacity-scale study was conducted using data from the Little Red Book (LRB) which has been referred to as “China’s Instagram.” Though the authors acknowledge there are some limitations in their methodology, they found that existing urban green spaces do not provide enough outdoor recreation facilities for the current demand, which leads to more clusters of outdoor recreational activity in the suburbs.

To estimate the full economic impact of outdoor recreation across Mesa County, Colorado, researchers measured the impact of both outdoor recreation-related businesses (such as retail trade and manufacturing) and tourism. In 2019, the GDP impact of outdoor recreation was $484,474,065 or 7.2% of total GDP; the direct job impact was 9,897 jobs or 11% of total jobs in Mesa County.

Utah State University researchers found that the creation of the Bears Ears National Monument in San Juan County, Utah, has likely increased outdoor recreation volume and growth in outdoor recreation-related industries. Retail trade, scientific, professional, and technical services as well as food services have all experienced significant economic growth in the three years after the monument was created. The researchers expect that the monument’s creation will ultimately result in a long-term increase in outdoor recreational activity in the county. 

The George S. Mickelson Trail (GSMT) is a multipurpose recreational trail that spans 114 miles across South Dakota beginning in the Black Hills. Researchers compiled survey data from 2,388 trail users who resided outside of the Black Hills Region. They analyzed the perceptions and use patterns of tourism activity on the GSMT and found that respondents were primarily attracted to the trail by the scenery and mountain biking opportunities. Their marketing recommendations include increasing promotion strategies such as providing more shuttle services, creating an online system to buy daily and annual passes, and administering more information about the trail through online advertising and brochures.

West of Atlanta, Georgia, the Silver Comet Trail plans to double its 61 miles. This is expected to bring more than 500,000 new tourist visits and $30 million in new spending to the area, while also generating substantial new tax revenues for the state through taxes on sales, income, and newly developed residential properties near the trail.

This large study of U.K. residents finds that those who walk or bike to work have significantly lower incidence of and mortality from cancer and cardiovascular disease. Those who incorporate cycling into their commute had the greatest reduction in risk of disease incidence and mortality.

A formal walking program for children diagnosed with attention deficit hyperactivity disorder (ADHD) finds that low-intensity walks in an urban park are associated with significantly greater improvement in cognitive function than similar walks in residential or downtown settings. The improvements measured are on par with improvements associated with the most typical medications prescribed for ADHD, and cognitive performance for participants after walking is comparable to the average performance of children who have not been diagnosed with ADHD.

A daily afterschool program in Miami-Dade County, Florida observes significant decreases in body mass index (BMI) and blood pressure between the beginning and end of the school year. Findings from this research suggest consistent, long-term afterschool programs can effectively reduce childhood obesity and cardiovascular disease risk.

In this large-scale study of participants in a formal walking program in the U.K., researchers find that participants in nature-based group walks are less likely to report experiencing depression, perceived stress, and negative affect, and report greater overall mental well-being. By comparing a large sample of participants and non-participants over time, the authors overcome some inherent challenges in measuring the effectiveness of these types of programs.

In Taos, New Mexico, Hispanic residents and low-income residents are less likely to have used trails during the previous year, but those who have used trails during the previous year use them just as often as other (non-Hispanic) residents. Among low-income residents, those with a park or trail within a 10-minute walk of their house were 50 percent more likely to have used trails during the previous year.

Research has established that low-income people tend to have higher mortality rates than high-income residents. This study across all of England demonstrates that this gap in mortality rate is about half the size in areas with the most green space compared to areas with the least green space.

At a sample of recreation centers in southern California, researchers find that several measures of facility condition and amenities are better in high-income neighborhoods relative to low-income neighborhoods. The likelihood that a child uses the recreation center increases 23 percent for each $10,000 increase in neighborhood income, but the authors do not find a relationship between the quality of the facility and participation rates.

A large study of 50 urban parks in Southern California measures park use by nearby residents and other users across high-, medium-, and low-poverty areas, finding that parks are used less in high-poverty areas. Those who do use parks in high-poverty areas, however, on average use the parks more per week, are more likely to see familiar people in the parks, and use the parks more when there are more staff present.

In Burlington, Vermont, a lakefront trail is visited mostly by locals, who use it for both recreation and transportation. Closest to downtown Burlington, non-locals use the trail as much as locals and non-local day trips account for the greatest spending in the community.

In rural Nova Scotia, a proposed trail is expected to increase substantially the amount of physical activity of local residents, with over half of respondents predicting increased physical activity due to the trail. For every dollar spent constructing the trail, it is expected to generate at least $2 in avoided health care costs.

In eastern Pennsylvania, the D&L Trail receives approximately 283,000 visits annually, nearly half of whom report using the trail at least once a week. Although the economic impact estimates likely are significantly overstated, the trail’s effect on nearby residents’ health is a substantial, valuable asset.

In rural Bonner County in northern Idaho, trails are used by three-quarters of residents an average of every day in the summer and every other day in the winter. Trail use is high for all residents, even accounting for differences in the length of residence in the county, income, and age. Business owners are more likely to identify trails as an important factor in their decision to move to the county.

In rural Nova Scotia, a proposed trail is predicted to attract 160,000 users per year. Because motorized vehicle use is expected to diminish the quality of non-motorized users’ experience, allowing all-terrain vehicles on the trail is predicted to cut the number of total visits in half.

A media campaign to promote a trails information site in Las Vegas, Nevada appears to have significantly increased trail use across most trails studied. The size of the gain in trail use appears to be independent of trail lighting, landscaping, and trail length.

The Erie Pittsburgh Trail, a network of six connected rail trails in rural northwest Pennsylvania, draw 158,507 users each year. Nine of ten trail users are from Pennsylvania and more than half of all users are riding bikes.

Across upstate New York, the 277-mile Erie Canalway Trail is associated with 1.6 million annual visits, only three percent of which come from outside the region. However, because those non-locals spend large amounts on lodging, the trail generates more than $55 million in spending annually.

Visitors to walking trails in rural Ireland are likely to spend more to visit flat or valley trails, as well as trails that have signage and maps. The authors use the results to evaluate a set of proposed trails to identify those most likely to bring the most visitors and generate the greatest economic impact.

In Durham, North Carolina, a bicycle-pedestrian bridge was built to connect two previously separate segments of a regional trail, leading to a 133 percent increase in trail use after its construction. This new connection allows the researchers to demonstrate a substantial increase in physical activity attributable to the bridge, with significant public health benefits for trail users.

This thorough study of a 111-mile regional trail network around Columbus, Ohio found that trail users travelled roughly 11.9 million miles in 2014, mostly by bicycle. Higher population density, easy access from neighborhoods, connection to other trails, and longer trails are associated with greater use.

Non-motorized trail users in Oregon account for 162.3 million user days per year, and the vast majority of these days are spent walking or hiking. While these recreation days are associated with substantial expenditures, the amount spent per person per day and the total economic impact vary greatly within the state.

Although visitor spending per day along the Overmountain Victory National Historic Trail in western Virginia, Tennessee, North Carolina, and South Carolina is relatively low, the large number of visitors generates substantial economic impact. However, much of this spending is likely due to the attraction of specific historic sites and not the trail, because relatively few visitors were aware that the historic sites are connected to a larger regional trail.

In northern Wisconsin, 95 percent of participants in non-motorized events are non-local, and these participants take more than four trips per year to the area on average, generating substantial economic impact. The two most important factors affecting non-residents’ decision to visit were the quality of trails and the quality of trail mapping and signage.

A 98-mile rail trail in northern Wisconsin and Minnesota attracts roughly 46,400 visits per year, with trail users spending $118 per trip, on average. Despite high visitation and spending, the trail’s economic impact could be increased with better connections between nearby towns, and through businesses-like bike shops that target trail users.

In Jackson Hole, Wyoming, a random, statistically representative survey gathered information about residents’ opinions of pathways and trails, including levels and types of use, satisfaction, strengths and weaknesses, and the role the trail system plays in quality of life. The survey found that 91 percent of residents had used the trail system in the previous 12 months and the trail system functions well for recreation, but could use improvements to serve transportation needs.

Combining data from 10 U.K. studies, researchers demonstrated statistically significant improvements in self-esteem and mood after participants exercised outside in a natural setting. Although all cohorts and types of settings experienced improvements, the greatest gains are visible after short duration, light exercise, and among the mentally ill.

Trails in Lincoln, Nebraska have the potential to generate large benefits for trail users in terms of avoided medical costs. These benefits may significantly outweigh the per capita cost of trail construction and maintenance. However, due to simplifying assumptions made regarding both benefits and costs, the cost-benefit ratios are unreliable.

This study found that the North Central Rail Trail is used heavily by residents who lack safe walking and cycling alternatives on local roadways; trail use grew 42 percent per year during the first decade it was open. Both residents and nearby property owners overwhelmingly found the trail a good investment of public funds and would support state-funded trails built elsewhere in the state.

This study found that the Coastal Georgia Greenway has the potential to generate substantial economic impact along its route. Using findings from studies on a range of existing rail-trail projects, the study projects use and economic impact for the year the trail is constructed as well as five years later, after more people learn about the trail.

This study found that cycling and pedestrian activities in Vermont generate substantial state-wide economic impact through the construction and maintenance of trails, businesses serving cyclists and pedestrians, and events.  Although not quantified in this study, trails also provide benefits to residents through avoided transportation costs for consumers (e.g., gasoline and vehicle maintenance), avoided transportation costs for the public (e.g., reduced maintenance costs due to fewer vehicle trips), and increases in real estate values near trails.

This study found that the economic impacts of cycling and walking active infrastructure construction, cycling and walking-related businesses, and cycling and walking events in New Jersey are eight times the amount spent on constructing these facilities in the same year.

This study found that the Burke Gilman Trail in Seattle is most often seen as an asset by those who moved to the neighborhood after it was built, while those who have lived there since before the trail was built are less likely to see the trail as increasing the sales price or ease of selling their home. Crime associated with the trail is negligible and adjacent property owners’ biggest concern is privacy.

This study found that older women in Pittsburgh, Pennsylvania walk more overall if they live within walking distance of a trail, and those who use trails use them at least twice per week. Proximity to trails had the strongest relationship with increased walking among 14 neighborhood destinations, including parks, retail establishments, and public services.

This study found that in Morgantown, West Virginia, one-quarter of trail users had not been active before the trail was built, and who report large increases in physical activity since they began using the trail. For most of these newly-active residents, the trail was the only place where they exercised and they report the trail’s safety, paved and flat terrain, and convenience as the most important considerations in deciding to use the trail.

This study found that walking trails in rural, southeastern Missouri communities are associated with the greatest increase in exercise for those most at risk of inactivity, particularly those who were not already regular walkers, have a high school education or less, or who earn less than $15,000 per year. Trails that were at least a half mile long, paved, or located in the smallest towns were associated with the largest increases in exercise.

This study found that Illinois’ regional trails receive very high use, mainly cycling and walking, particularly in metropolitan areas. Trails mostly generate benefits in terms of health impacts for local residents, one-third of whom used trails at least 21 times in the previous year and exercised for at least 150 minutes during each trail visit.

This study found that walkers and hikers, while they have fairly low per-trip spending, generate nearly two-thirds of the total economic impact from trails-related recreation in Minnesota because many people participate and they participate often. Motorized recreation–both summer and winter–has the highest individual expenditures per trip.

This study found that across all regions in Minnesota, walkers and hikers are the largest group of trail users and account for most of the local spending, with half of the users in northern and central regions coming from the Minneapolis-St. Paul area. Activities such as ATV and snowmobiling are relatively small statewide in terms of users and spending, but they are very important sources of income in smaller communities in the northwest and northeast parts of the state.

This study found that development of a trail and associated infrastructure has contributed to the revitalization of downtown Winter Garden, Florida. In this county-wide trail system, the trails with the most access points to businesses had the greatest measurable economic impact, but the complement of trails throughout Orange County–some urban and others natural and quiet–contribute to an appealing regional trail system.

This study found that many businesses near the Great Allegheny Passage (GAP) have experienced increased revenue due to their proximity to the trail, and expect to expand operations to meet demand. The greatest economic impact comes from overnight trail users, who spend seven times as much as day users.

This study found that although user spending on this long-distance Pennsylvania trail is modest, it draws a relatively large number of visitors to the small towns through which it runs. The roughly one in ten users who stay overnight spend substantially more than day visitors.

This study found that while 70 percent of Missoula residents were willing to pay more taxes to acquire open space and build new trails and recreation facilities, still more (77%) were willing to pay more taxes to maintain existing facilities. Eighty-six percent of all residents had used City parks in the previous 12 months, highlighting the importance of within-community trails even in rural areas with public lands nearby.

This study on the Virginia Creeper Rail Trail in Virginia is unique in that it estimates both economic impacts, measured as local spending by tourists, and economic benefits, measured as value to individual users. This paints a more complete picture of the total value of a trail than considering only one of these economic measures, an approach that may be particularly helpful when prioritizing the use of government funds.

This study found that the Perkiomen Trail in Pennsylvania is a benefit to locals’ quality of life more than an economic driver, as it is used most frequently by local residents. However, disagreements with adjacent landowners over rights-of-way prior to trail construction linger, and may provide a lesson on the importance of carefully managing adjacent landowner relationships.

This study found that landowners adjacent to the Mohawk-Hudson Bike-Hike Trail are frequent users of the trail, and most are satisfied with having the trail as a neighbor. Despite their general approval of the trail, most landowners did not think the trail would increase their property value or affect how quickly they could sell their home, suggesting that the main appeal of living near the trail comes from being able to use it.

This study found that trails in six Indiana cities are very popular with residents, especially those who live closest to the trail, and including residents in volunteer patrols and maintenance can improve the trail experience for others and solidify residents’ support for the trails. The benefits of these trails can be expanded if cities are able to increase use by commuters and visitors.

This study found that the Washington and Old Dominion (W&OD) Trail generates significant local economic impact, even though it is primarily used by locals. Using a creative set of questions, the authors identify which trail features are sufficient and which should be higher priorities for funding.

This study found that the Little Miami Scenic Trail in southwest Ohio is associated with higher property values for nearby properties, across the urban, suburban, and rural sections of the trail. On average, homes sell for an additional $7 for every foot closer to the trail, up to about a mile away from the trail. For example, a house a half mile away from the trail would sell, on average, for $18,612 less than a house that is identical in all other aspects but is adjacent to the trail.

This study found that trails and greenbelts in a San Antonio, Texas neighborhood are associated with higher home values, particularly if the trails are incorporated into a greenbelt. This effect is not just for homes immediately adjacent to the trail, but for all homes in the neighborhood.

This study found that, according to the residents closest to the trails, the Omaha trail system has had an overwhelmingly positive effect on neighborhoods’ quality of life. The positive effects are not constant across all trails and neighborhoods, though, and neighborhoods that saw the greatest benefit were constructed concurrently with the trails.

This study found that the proposed Catskill Mountain Rail Trail in New York is well-situated to provide new recreation opportunities in an area that is already a recreation destination (Catskill Mountain Park), and has a large nearby population base to draw from (New York City). These factors result in a substantial potential economic impact for the trail.

This study found that even in very rural places, developed trails provide valuable recreation opportunities for residents in addition to attracting new visitors and spending by non-locals. The results also suggest that trails contributed to increased community pride and a modest increase in activity levels, with few problems from crime or vandalism related to the trails.

This study found that the benefits of trails in Indian Country may be more significant than in other communities that are less culturally or spatially fragmented, less politically and economically marginalized, or less culturally tied to the landscape. Trails can provide particularly valuable benefits to residents of Indian Country, helping to improve residents’ quality of life in several dimensions: connecting tribal members to each other and to culturally significant sites and natural resources; providing safe alternative transportation routes across the reservation; providing opportunities for safe exercise; and providing opportunities for economic development and cultural education.

The study found that neighborhoods with access to and views of the trail command higher property values, and that these higher property values generate additional tax revenue for municipal and county governments. Trails may not pay for themselves based solely on higher property tax revenue, but the likely additional revenue would offset some of the expense.

This study found that locals are the main beneficiary of the Teton County, Wyoming trail system, although visitors are increasingly enjoying area trails outside of Teton and Yellowstone National Parks. The economic impact of the trails may be significant, but is difficult to estimate without knowing how many visitors come to the area just for the trail system.

This study found that the Pine Creek Rail Trail is a popular destination trail for cyclists in Pennsylvania, most of whom stay overnight. Although the estimates of use and economic impact are imperfect, they do show that the trail is responsible for bringing many people to the area who otherwise would not have come.

This study estimates future use on a proposed rail-trail in Georgia, while most trail studies estimate use on an existing trail. It found that the best predictors of future trail use are how close the person lives to the trail, whether they had ridden bicycles in the previous year, and whether they had used a rail trail previously; age and income were not related to predicted use.

This study found that the qualitative benefits to property owners–including access to recreation and the natural world and connection to neighbors–far outweigh the negative effects of living adjacent to a multiuse trail in this study. The negative effects, including trespassing, less privacy, and dog waste, were not widespread across users and may be mitigated with trail design.

This study found that extending a rail-trail from the outskirts of Fall River, Massachusetts into the city center is likely to generate a range of benefits for the community, including increased physical activity, fewer pedestrian and cyclist crashes with motor vehicles, increased business activity and improved working environment, and less air pollution. This study is an example of a small city’s Health Impact Assessment, a single document that can be used by trail planners and advocates to justify the investment of public funds.

This study found that rural communities have a high demand for dedicated cycling and pedestrian infrastructure, separate from main roadways, and users are willing to pay small fees to use these trails. These trails are most likely to be used by those living close to small towns and villages, who use the trails for recreation and transportation.

This study found that trail users are willing to incur greater expenses and travel further to use rural trails, and spend more time on those trails while they are there, indicating these trails are enjoyed by both locals and non-locals. Urban trails, on the other hand, are mainly a resource for local residents, and are used much more frequently and for shorter periods of times.

This study found that in Indianapolis property values are higher when homes are located near conservation areas without trails or near high-profile, destination trails, but are not any different when they are located near less-popular trails. Individual trail users place a positive value on being able to use trails, which is sufficiently high to justify the expense of trail construction and maintenance.

This study outlines a step-by-step process for estimating trail use, breaking the process down into four primary steps. The authors illustrate how to apply the method using a simple case study on the Buffalo Valley Rail Trail in Pennsylvania.

This study found that destination trailheads for non-local users along this long-distance trail system near Pittsburgh, Pennsylvania are associated with the greatest spending per person. This study demonstrates that the economic impact of a trail varies along its length, depending on the types of users the trail attracts and how well the local community can capture their business.

This study found that a community rail-trail in West Virginia encourages new physical activity among inactive residents and greater physical activity for those who were already active, and that for many community members trail use is their only form of exercise. Trail cost per newly active resident is on the lower end of health interventions aimed at encouraging sedentary individuals to become active, and is likely to reach more people that other common interventions.

This study found that three-quarters of trail users in Lincoln, Nebraska report being more physically active since they began using trails, most of whom are active for general health. The cost per user who is more active since they began using the trails is $98, less than other programs aimed at increasing physical activity.

This study found that residents who live closer to rail-trails in Arlington, Massachusetts got an hour more exercise for transportation purposes each week. Proximity to the trails had no effect on the amount of exercise for recreation, suggesting the neighborhood trails in this community are mainly used for transportation purposes.

This study found that a marketing campaign to promote the opening of a new rail trail in Sydney, Australia did little to increase awareness of the trail or increase trail use in the general population. However, it was effective in raising awareness of those who lived closest to the trail.

This study found that homes within 50 meters of bike paths in New Castle County, Delaware sold, on average, for 4 percent more than similar homes without bike paths. These results are consistent with other studies that have demonstrated a higher value for homes adjacent to trails.

This study found that people who used a new rail trail in Durham, North Carolina reported exercising more during the month after it opened, although it did not appear that their minutes spent exercising per week was actually any higher than before the trail opened. Potential effects of new trails on physical activity may take longer to manifest themselves in residents’ habits, and the effects likely depend on how many trails are already nearby.

This study found that in southeastern Missouri, public health interventions to increase residents’ trail use, such as newsletters and fun walks, had no statistically-observable effect on residents’ walking habits or physical activity. A third of those who use the trail report increased overall physical activity levels since they began using the trail, suggesting while that trails can increase community physical activity, a primary challenge is getting residents to begin using them.
