Abstract:The purpose of this document is to report the results of the study that reviewed the impact of bicycle corridors on travel demand throughout the state of Utah. To meet the objectives of the study, bicycle rate data were collected and evaluated at numerous data collection sites across Utah's urban county roadways. In order to accomplish this data collection effort, two primary methods were used to collect bicycle volume data. The first method was to use automatic bicycle counters on roadways that had bicycle infrastructure. The second method was to gather bicycle volume data through manual counts on roads with and without bicycle infrastructure. Comparisons of the bicycle rate data to the following five roadway characteristic variables were conducted: Annual Average Daily Traffic (AADT), posted speed limit, number of lanes, roadway classification, and presence (or lack of) bicycle infrastructure in adjacent corridors. Additionally, the research team compared rate data provided by the Mountainland Association of Governments (MAG) on three shared use paths to demonstrate recent trends in path usage. Comparison of bicycle rates to AADT resulted in no correlation or statistical relationship in the data but the data do suggest trends. Statistically significant results did occur when comparing bicycle rates to posted speed limits. No statistically significant relationships occurred when comparing bicycle rates to the number of lanes or roadway classification. It was determined that roadways with bicycle infrastructure tend to yield higher bicycle rates than roadways that do not have bicycle infrastructure. Lastly, using shared use path data it is determined that bicycle rates on shared use paths have increased between 1.7 to 7.5 percent from 2013 to 2014 and it is assumed that a similar trend would exist on bicycle infrastructure in the communities.
