CHICAGO—The death of a woman whose bicycle collided with a truck on Friday is believed to be the first fatality involving the rapidly growing bike-share programs in the U.S., industry officials said. 
 
 Such programs—which typically involve renting a bike from an automated station by paying a daily fee, or using a keychain token for annual members—have been spreading rapidly in recent years and can now be found in at least 40 U.S. cities.

 ABSTRACT 
 
 The growth of bikesharing in the United States has had a transformative impact on urban transportation. Major cities have established large bikesharing systems, including Boston, Chicago, Denver, Minneapolis-Saint Paul, New York City, Salt Lake City, the San Francisco Bay Area, Seattle, Washington DC, and others. These systems began operating as early as 2010, and no fatalities have occurred within the US as of this writing. However, three have happened in North America—two in Canada and one in Mexico. Bikesharing has some qualities that appear inherently unsafe for bicyclists. Most prominently, helmet usage is documented to be quite low in most regions. Bikesharing is also used by irregular bicyclists who are less familiar with the local terrain. In this study, researchers take a closer look at bikesharing safety from qualitative and quantitative perspectives. Through a series of four focus groups, they discussed bikesharing usage and safety with bikesharing members and nonmembers in the Bay Area. They further engaged experts nationwide from a variety of fields to evaluate their opinions and perspectives on bikesharing and safety. Finally, researchers conducted an analysis of bicycle and bikesharing activity data, as well as bicycle and bikesharing collisions to evaluate injury rates associated with bikesharing when compared with benchmarks of personal bicycling. The data analysis found that collision and injury rates for bikesharing are lower than previously computed rates for personal bicycling. Experts and focus group participants independently pointed to bikesharing rider behavior and bikesharing bicycle design as possible factors. In particular, bikesharing bicycles are generally designed in ways that promote stability and limited speeds, which mitigate the conditions that contribute to collisions. Data analysis also explored whether there was evidence of a “safety in numbers benefit” that resulted from bikesharing activity. However, no significant impact from bikesharing activity on broader bicycle collisions could be found within the regions in which they operate. Discussion and recommendations are presented in the conclusion.

 Keywords: Bikesharing, Safety, Bicycle, Collisions ||||| A 25-year-old woman riding a Divvy bike who died Friday morning following a crash involving a flatbed truck in Chicago's Avondale neighborhood is believed to be the first person killed while riding a bike-sharing bicycle in the United States. 
 
 The crash happened about 9 a.m. near Sacramento and Belmont avenues, said Officer Jose Estrada, a police spokesman, citing preliminary information. The truck and the bicyclist were both traveling north on Sacramento, when both turned east at Belmont and collided, Estrada said. 
 
 The woman was taken in critical condition to Advocate Illinois Masonic Medical Center and later pronounced dead, Estrada said. She was identified by the Cook County medical examiner’s office as Virginia Murray, 25, of the 1200 block of North Marion Court in the Wicker Park neighborhood. 
 
 The woman's death is believed to be the first bike-share fatality in the United States since the first bike-share program started in Tulsa, Okla., in 2007, according to Paul DeMaio, principal of Washington, D.C.-based MetroBike, a bike-share consulting business.

 “This is really unfortunate. My heart goes out to the family members and friends of the person who was killed. Hopefully this will lead to the hastening and the growth of networks of bike infrastructure not only in Chicago but throughout North America.” 
 
 In a joint statement, the Chicago Department of Transportation and Divvy expressed their “deepest condolences to the rider’s family and loved ones.” 
 
 Nearly 8 million rides have been taken on the Divvy system since the bikes were brought into Chicago in June 2013. 
 
 “It’s a tragic reminder that we still have work to do to make our streets safe for everyone,” said Jim Merrell, advocacy director for the Active Transportation Alliance, which promotes safe biking, walking and transit. He said the Alliance looks forward to the release this fall of the city’s “Vision Zero” plan, the goal of which is eliminating traffic fatalities. 
 
 “We believe all fatalities on our roadways are preventable,” said Merrell. 
 
 The police department’s Major Accident Investigation Unit was investigating. 
 
 A Mineta Transportation Institute study released in March found the rates of collision and injury among bike-sharing participants were lower than the rates among regular bicyclists. 
 
 Transportation experts have attributed the lower collision and injury rate to a number of factors, including the shared bike’s bulky, heavy design, which cuts speed, discourages risky maneuvers and increases visibility. 
 
 Bike-share programs have proliferated to over 32,000 bikes in about 100 U.S. cities over the last nine years, including Evanston and Oak Park, which got Divvy bikes this week. There have been bike-share deaths in other countries, including Canada and Mexico.
– A 25-year-old woman taking advantage of Chicago's bike-sharing service died Friday morning after she and a flatbed truck turned at the same time and crashed— reportedly making her the first bike-share fatality in the US since the service first debuted in Oklahoma in 2007, a bike-sharing consultant tells the Chicago Tribune. Per DNAinfo, the woman on the Divvy bike, IDed by the Cook County medical examiner as Virginia Murray, tried to make a turn east from Sacramento Avenue to Belmont Avenue and smashed into the truck making the same turn; a witness says she was thrown 6 feet into the air before crashing to the ground. Murray suffered severe injuries to her upper body and was pronounced dead at a local hospital. Bike-sharing programs—where riders pay a fee to pick up a bike at a self-serve station, then drop it off at another location when they're done—are increasing in popularity around the US, with the Wall Street Journal noting there are about 40 currently in existence. And while the Mineta Transportation Institute has noted bike sharing can be seen as being "inherently unsafe" for bicyclists (including riders not using helmets and not being familiar with a city's landscape), a study found "collision and injury rates for bikesharing are lower" than rates for regular cyclists. (Police say Murray was wearing a helmet, per the Journal.) Still, an Active Transportation Alliance director tells the Tribune that Murray's death is "a tragic reminder that we still have work to do to make our streets safe for everyone." In a statement, Divvy and Chicago's DOT shared their "deepest condolences to the rider's family and loved ones," per the Tribune, with the paper noting that Divvy has provided almost 8 million rides since it was introduced in the Windy City three years ago. (A GOPer thinks bike sharing is a conspiracy.)
