To reflect current cyclists' preferences and safety data, bicycle engineering guidelines often used by state regulators to design bicycle facilities need to be overhauled.
Reflector Technology in Footwear and Bicycle Helps in Detecting Bioterror Threats
Researchers are using smaller versions of reflectors found in sneakers and bicycle fenders to detect bioterrorism threats and diagnose everyday infectious disease.

Standards set by the American Association of State Highway and Transportation Officials (AASHTO) in its Guide for the Development of Bicycle Facilities generally serve vehicles well but overlook most bicyclists' needs, according to lead author Anne Lusk, research scientist in the Department of Nutrition at HSPH, who has been studying bicycling patterns in the U.S. and abroad for many years. "In the U.S., the default remains the painted bike lane on the road," she said, which is problematic since research has shown that women, seniors, and children prefer not to ride on roads with traffic.
According to the researchers, the AASHTO guidelines discouraged or did not include cycle tracks due to alleged safety concerns and did not cite research about crash rates on cycle tracks. This study analyzed five state-adopted U.S. bicycle guidelines published between 1972 and 1999 to understand how the guidelines have directed the building of bicycle facilities in the U.S. They also wanted to find out how crash rates on the cycle tracks that had been built compared with bicycle crash rates on roadways in the U.S. They identified 19 cycle tracks in 14 cities in the U.S. and found these cycle tracks had an overall crash rate of 2.3 per one million bicycle kilometers ridden, which is similar to crash rates found on Canadian cycle tracks and lower than published crash rates from cities in North America for bicycling in the road without any bicycle facilities.
Old Men Advised to Ride Women�s Bicycles to Avoid Injuries
Researchers advise old men to ride bicycles designed with low crossbar as in women’s bikes to avoid injury during getting on and off the bikes.

The authors concluded AASHTO bicycle guidelines should be based on more rigorous and up-to-date research. If policies could allow for easier construction of cycle tracks, studies have indicated that more individuals would be willing to bicycle. Encouraging more cycling would be helpful for weight control, heart function, and would boost physical fitness for children and adults in addition to helping to reduce traffic congestion and air pollution from vehicles, said the authors.
