Intercept Survey Data

The Connecticut Trail Census facilitates the collection and use of two types of data: count data (# of uses) and intercept survey data (user behavior).  

    • Intercept survey data is collected by volunteers who conduct surveys intercepting trail users.
    • The survey consists of multiple choice and open ended questions on a variety of trail use topics such as distance traveled to use the trail, primary reason for using the trail, and demographic information about who is using the trail.

Aggregated Data Reports

2018 Aggregated Survey Data Report

March 15, 2019

This is a summary of intercept survey data collected from May to December, 2018 on multi-use trails participating in the Connecticut Trail Census.  Data was collected by local volunteers who received supplies and training from the Connecticut Trail Census and data was provided on a voluntary and de-identified basis to the University of Connecticut Extension for analysis. In 2018, ten of the sixteen participating (63%) sites collected an aggregated total of 1,146 surveys. This report includes some analysis of 2017 and 2018 data.

2017 Intercept Survey Data Report

February 12, 2018

This is a summary of intercept survey data collected from May to September, 2017 on multi-use trails participating in the Connecticut Trail Census. Of the fifteen multi-use trails included in this study, eleven trails provided intercept survey data. The actual site of the data collection was chosen to accurately represent normal trail use along the trail segment. These sites varied slightly from the locations chosen for infrared counts (not included in this summary).  This is an abbreviated summary of the data.

Understanding the Survey Data- Key Points

Data should not be generalized

The citizen science based structure of this study creates some significant challenges with regard to generalization and communication of the data collected.  The user identified nature of the sampling collection points means that sites selected to participate in the Trail Census may not necessarily be an accurate sample of bicycle/pedestrian trails in the state.  Further, given that the data collected represents use within a particular community around a data collection point, the data cannot be used to accurately estimate total use along the entire length of a trail.  

Following the pilot period of data collection in 2017, a significant effort was made to identify and reduce the potential sources of error.  Because this will never be a fully research based design however, the data should alway be viewed as not broadly generalizable or representative of the full population of trail users.   The goals in this review effort were to decrease the margin of error of volunteer administered intercept surveys while also increasing Site Coordinators and volunteers’ ability to successfully administer them.
