A nice page about how to teach a child bicycling and the related safety skills--breaking down the skills and abilities needed by age group.

Safety in numbers: more walkers and bicyclists, safer walking and bicycling by P L Jacobsen, published in Injury Prevention, 2003: A motorist is less likely to collide with a person walking and bicycling if more people walk or bicycle. Policies that increase the numbers of people walking and bicycling appear to be an effective route to improving the safety of people walking and bicycling.

The dangers of bicycling on a "sidepath"--a sidewalk or multi-use path alongside a roadway--transportation researchers have known for many years that bicycling on a path alongside a road is more dangerous than bicycling in the road itself. This page has a concise summary of the reasons.

Reasons for using, and how to use, the "Bicyclists may use full lane" signs [PDF file]. A report from the NCUTCD committee that is recommending that this sign be officially adopted in the Manual of Uniform Traffic Control Devices (MUTCD). In the meanwhile the sign may still be used under MUTCD--the report is simply suggested a single uniform version of the sign be adopted as standard by MUTCD. The sign articulates a law that is in effect in all 50 states, which states that when the lane is too narrow to share between a motorist and bicyclist (any less 12 ft or less) then the bicyclist may use the full lane and is not required to squeeze to the right to share with the motorist.
