The number of bicyclists killed on U.S. roadways is trending upward, particularly for certain subsets of the population, according to a report released today by the Governors Highway Safety Association (GHSA). GHSA’s Spotlight on Highway Safety: Bicyclist Safety notes that yearly bicyclist deaths increased 16 percent between 2010 and 2012, while overall motor vehicle fatalities increased just one percent during the same timeperiod.
The report’s author Scientist Dr. Allan Williams, analyzed current and historical fatality data to uncover bicyclist crash patterns. There have been some remarkable changes. For example, adults 20 and older represented 84 percent of bicyclist fatalities in 2012, compared to only 21 percent in 1975. Adult males comprised 74 percent of the total number of bicyclists killed in2012.
Bicycle fatalities are increasingly an urban phenomenon, accounting for 69 percent of all bicycle fatalities in 2012, compared with 50 percent in 1975. These changes correlate with an increase in bicycling commuters – a 62 percent jump since 2000, according to 2013 Census Bureaudata.
While bicyclists killed in motor vehicle crashes increased in 22 states between 2010 and 2012, six states – California, Florida, Illinois, New York, Michigan and Texas – represented 54 percent of allfatalities.
“These are high population states with many urban centers,” pointed out Williams, “and likely reflect a high level of bicycle exposure and interaction with motorvehicles.”
There are some bicycle fatality data that remain unchanged over the decades. Bicyclists killed are predominantly males (88 percent in 2012), and lack of helmet use and alcohol impairment continue to contribute to bicyclist deaths. In 2012, two-thirds or more of fatally injured bicyclists were not wearing helmets, and 28 percent of riders age 16 and older had blood alcohol concentrations (BAC) of .08 percent or higher, compared with 33 percent of fatally injured passenger vehicle drivers.
“What’s notable here,” said Dr. Williams, “is that the percentage of fatally injured bicyclists with high BACs has remained relatively constant since the early 1980s and did not mirror the sharp drop in alcohol-impaired driving that occurred among passenger vehicle drivers in the 1980s and early 1990s.”
Several states are adopting Complete Streets policies, which take into consideration all travel modes when building and/or improving existing roadway systems. They are also stepping up efforts to collect information on bicycle crash patterns and locations, which is critical for making informed decisions about countermeasures and resource allocation.
