Summary
This study evaluates the efficacy of using smartphones to collect bicycle travel data, addressing the need for inexpensive and efficient methods to understand cyclist route choices and facility preferences. Traditional data collection methods, such as intercept surveys or distributing dedicated GPS units, are often costly and time-consuming. The researchers hypothesized that leveraging existing smartphone technology could provide a rich dataset to guide infrastructure decisions, potentially increasing bicycle mode share and reducing congestion. The project utilized the CycleTracks application, developed by the San Francisco County Transportation Authority, to track cyclist locations via GPS. Austin, Texas, was selected as the case study due to its strong cycling culture and university presence. The experimental design involved recruiting volunteer bicyclists in the Austin area to download and use the CycleTracks app between May 1 and October 31, 2011. Participants were encouraged to log their trips, with the option to provide demographic information, including age, gender, cycling frequency, and zip codes for home, work, and school. Following each trip, users could define the trip purpose. The researchers collected over 3,600 recorded routes from the application’s servers. Data preparation involved cleaning the GPS data, completing the street network by adding missing links, and using ArcGIS algorithms to map-match the GPS points to the road network. Approximately 90 percent of the bicycle routes were successfully matched. The analysis revealed that about 300 participants provided demographic data, with 83 percent indicating they cycle daily or several times per week. The participant pool was predominantly male (70 percent) and concentrated in the 20–29 age range. Most participants lived and worked in central Austin. Regarding trip purposes, 85 percent of the recorded trips were for transportation rather than recreation. The dataset provided detailed attributes regarding route choices, allowing researchers to analyze preferences based on road class, land use, and other network features. Despite challenges in data cleaning and map-matching, the volume and detail of information gathered exceeded what is typically available through other collection methods. The study concludes that smartphones are a viable and valuable tool for collecting bicycle travel data. The ability to gather extensive route data alongside user demographics and trip purposes offers planners critical insights into route choice decisions. This information can inform the prioritization of bicycle infrastructure projects, improve safety accommodations, and support livability initiatives. The researchers recommend that communities consider smartphone applications as a cost-effective alternative to traditional surveys for understanding bicycling patterns and guiding future facility development.
Key finding
Researchers successfully matched almost 90 percent of the bicycle routes collected via the CycleTracks application, providing a dataset that far exceeds the information available from other data collection methods.
