This study assessed test-retest reliability of an interviewer-administered trail survey.
An intercept survey was conducted with adults using 2 paved trails in Indiana and South Carolina (N = 295; mean age = 46.9 +/- 18 y). The survey included items on frequency and duration of trail use for recreation and transportation, other patterns of trail use, and sociodemographic characteristics. Fifty-five adults completed the survey twice (2-16 d apart; mean = 7.4 +/- 2.6 d). Test-retest reliability was assessed with Spearman rank correlation coefficients, Kappa coefficients, and percent agreement.
Kappa coefficients and percent agreement for 9 categorical items ranged from 0.65 to 0.96 and from 64.0% to 98.2%, respectively. Among these items, the lowest Kappas were found for perceived safety (0.65) and reported duration of visits for recreational purposes (0.67). Spearman rank correlation coefficients for travel distance to and on the trail and frequency of trail use during the past 7 days and past 4 weeks ranged from 0.62 to 0.93.
Though further assessments of this survey with different populations and types of trails may be warranted, its overall high reliability indicates it can be used by researchers and practitioners in its current form.
"A study design with multiple ITC sensors on each trail may better detect if incremental distance signage affects patterns of trail use. Intercept surveys with trail users, such as the instrument developed by Troped et al. (2009), could also help clarify changes in PA behavior. This study has several limitations, including the non-random nature of the control trails. "
[Show abstract][Hide abstract] ABSTRACT: Objective:
Communities are building or improving trail networks for biking and walking to encourage physical activity, but the relationship between trail environments and physical activity is not well understood. We examined the effect of a trail use intervention in Southern Nevada.
We monitored the usage of urban trails (n=10) in Southern Nevada before, during, and after an intervention which included a marketing campaign promoting trail use and the addition of way-finding and incremental distance signage to selected trails (October 2011-October 2012). Data were collected with infrared monitors placed on the trails for three periods of 7days. We compared pre-, mid-, and post-intervention usage rates on the 6 trails where signage was added to usage rates on the 4 control trails.
The groups of trails experienced different patterns of increases and decreases over the 1-year study period. Mean users per hour increased 31% for the study trails and 35% for the control trails (p<0.001), but the total increase did not vary between the groups.
Trail use increased about 33% during the 1-year study period for the intervention. Adding wayfinding and incremental distance signage appeared to support the increase in usage which followed the marketing campaign.

[Show abstract][Hide abstract] ABSTRACT: To better understand and promote physical activity on a newly constructed trail, the present study examined the demographic characteristics and physical activity behaviors of trail users; the demographic characteristics of trail users compared to the demographic profile Greenville County, South Carolina residents; trail users' purpose for using the trail; the distance trail users traveled to access the trail from their homes; channels through which trail users learned about the trail; and trail characteristics liked by trail users. Using a valid and reliable intercept survey, 1,148 trail users were interviewed. Trail users were mostly white (93.1%), male (59.1%) adults (84.2%) who reported using the trail for exercise (91%). Significant associations were identified between trail user demographic characteristics and how trail users learned about the trail and trail characteristics liked by trail users. The findings may contribute to the development of targeted health promotion efforts to promote physical activity on this and similar trails.

[Show abstract][Hide abstract] ABSTRACT: Rail trails are elements of the built environment that support the Task Force on Community Preventive Services' recommendation to create, or enhance access to, places for physical activity (PA). The purpose of this study was to examine the associations between sociodemographic characteristics and perceptions of the built environment with the frequency, type, and duration of PA among users of an urban, paved rail trail segment.
Interviewers conducted intercept surveys with 431 rail trail users and analyzed data by using logistic regression to estimate odds ratios between sociodemographic characteristics and perceptions of the built environment on the frequency, type, and duration of PA performed on the trail.
Adults who used the trail in the cool months, traveled to the trail by a motorized vehicle, used the trail with others, and had some graduate school education visited the trail less often. Younger adults, men, whites, and those with some graduate school education were more likely to engage in vigorous activities on the trail. Adults who traveled to the trail by a motorized vehicle spent more time engaged in PA on the trail.
Our results suggest that the most frequent users of a rail trail for PA are those who use the trail alone and travel to the trail by bicycle or on foot. Trails are an aspect of the built environment that supports active lifestyles, and future studies should evaluate different types of trails among more diverse populations and locations.
