(1) Cycling fatalities per cyclist = 3 yr. average number of cyclist fatalities /number of people who commute by bike.<br />

MANY STUDIES NOW SHOW THAT BICYCLING SAFETY INCREASES GREATLY AS cycling<br />

levels rise (Jacobsen, 2003). For this illustration, bike to work mode share from the ACS 2005 was<br />

compared to FARS bicycle fatality data. To figure the fatality rate, the project team divided the threeyear<br />

average number of bicycle fatalities by the number of people who bike to work. The result is<br />

a negative correlation (r=-0.55) that suggests greater cycling levels may mean increased safety <strong>for</strong><br />

cyclists.<br />
