Alan During, a writer for Gristmill, was inspired to do some research on the safety of riding a bike after a car ran his son off the road.
The data that Durning dug up are good news for cyclists. As the table below illustrates, riding a bike compares pretty favorably with other forms of transportation (if your commute involves a skydive, however, you may need to find an alternative.)

The above chart is based per hour. If we look at the data per mile, cars in the U.S. start looking better. Ten drivers and passengers die per billion miles in a car; this number goes up to 100 for cyclists.
Public transportation is ten times safer than cars per mile. Walking is three times more dangerous than cycling. However, the perception is that cycling is a super-dangerous activity, and many people (including folks leaving comments on some of Carectomy’s posts) don’t feel safe riding a bike. Based purely on reason, those looking to be safe should avoid walking and stick to public transit whenever possible.
Perhaps the most interesting nuggets of information Durning unearthed involved the positive health benefits reaped by cyclists. This regular dose of low-impact aerobic exercise makes cyclists healthier and prolongs their lives. The benefits by far outweigh the risks.
Similarly, Pedalling Health, an Australian study published in 1996, concluded that an hour of biking a day — normal for a regular bike commuter — prevents four times as much heart attack risk as it adds in collision risk. The iconoclastic British transport researcher Mayer Hillman did a study for the British Medical Association in 1992 (not online but summarized here and here) reportedly showing that for every year of life lost to a bike crash, twenty years of life are gained from stress reduction, greater cardiovascular fitness, and improved mental health. As I’ve noted, the time you spend in moderate exercise is added to your life, with interest.
We also need to work to change the common perception of riding a bike as an unsafe venture, and get people the heck out of their “safe” death-machine SUVs. As our post on the Right of Way organization indicates, cyclists are dramatically safer when there are more people riding.

The data is very interesting, and I’d like to know similar information for where I live (Ecuador). I lived in Japan for 3 years and over there I felt so safe riding my bike everyday for most of my daily chores. I rode my bike while pregnant and then with my baby on my back, and I felt very safe.
Back in Quito I wouldn’t dare to ride a bike on the streets with my toddler on it. It also depends on the neighborhood, but my general impression is that it could be very dangerous for a mom with a child.
We’re car free and use public transportation a lot, though.
