This project included four distinct but related exploratory studies of data sources that could improve roadway safety analysis. The first effort evaluated passively gathered crowdsourced bicyclist activity data from StreetLight Data and found promising correlations (R2 of 62% and 69% for monthly weekday and weekend daily averages) when the StreetLight data were compared to bicyclist […]
Bad assumptions make data from Weeks 1-14 insufficient. Please see accurate data from Week 15 forward. It is Week 9 of the coronavirus pandemic, and total crash data is still on the decline in Alabama. Crashes have declined to less than 40% of their pre-COVID levels, INCLUDING speed-involved and fatal crashes. View Graph This report comes […]

The Governors Highway Safety Association (GHSA) is launching a new partnership with Uber Eats to provide important road safety guidance to delivery partners who ride bicycles. GHSA worked with Uber Eats to develop eight critical safety tips that are being rolled out to bicycle delivery partners at events in major Uber Eats markets across the country, starting […]
Protected bike lanes separated from the roadway by physical barriers are relatively new in the United States. This study examined the risk of collisions or falls leading to emergency department visits associated with bicycle facilities (e.g., protected bike lanes, conventional bike lanes demarcated by painted lines, sharrows) and other roadway characteristics in three U.S. cities. […]
The electric bicycle (e-bike) is a recently introduced mode of travel that is rapidly gaining in popularity throughout the United States. The e-bike can offer a cheaper alternative to car travel and can provide users with an adequate level of physical activity intensity necessary to enhance health. Riding an e-bike is rewarding and fun, is […]
Better bike networks need safer intersections. Intersections are the place where the most vehicle-bike conflicts occur. In 2017, 43% of urban bicyclist fatalities occurred at intersections. On many streets, large turn radii and wide lanes encourage drivers to make sweeping, fast turns. These design decisions increase exposure and risk for people walking and biking, reduce […]
Cycling has been shown to have health and environmental benefits, but there are also inherent risks including serious and fatal injury. Head injuries are common among cycling hospitalisations and fatalities, and bicycle helmets have been designed to mitigate head injuries in a crash or fall. Biomechanical and epidemiological evidence suggests wearing a bicycle helmet substantially […]
