Bicycle Injury Interventions
Bicycle Skills Training & Safety Courses
Background
Prevention of bicycle injuries can be approached through the use of bicycle helmets,
educational programs to improve riding behavior and safet y, educational programs
aimed at motor vehicle drivers, and environmental changes to decrease the likelihood
of bicycle-motor vehicle collisions. An extensive review of educational programs
and environmental changes is posted else where on our website. Click Training
Programs for Bicycle Safety to access this review.
National Strategies for Advancing Bicycle Safety is available on the NBSN website.
This document includes goals, strategies, and short-and long-term actions that can
be taken to reduce injury and mortality associated with bicycle-related incidents.
Efforts to change the cycling environment have five key goals: motorists will share
the road, bicyclists will ride safely, bicyclists will wear helmets, the legal system
will support safe bicycling, roads and paths will safely accommodate bicyclists.
The Institute of Transportation Engineers (ITE) created a pedestrian and bicycle
task force in July 1999 to identify ways ITE could enhance its activities in this
area. Survey results and recommendations are available on the organization web site
at www.ite.org/councils/pbsurveyresults.htm.
Recently published evaluations are reviewed below.
Review of studies evaluating bicycle skills training &
safety courses:
Author | Macarthur, 1998 |
Study design and target population | Randomized controlled trial
Suburb of Toronto, Canada
3 Intervention schools (n=73)
3 Contol school (n=68) |
Intervention | Bicycle handling skills; Kids-CAN-BIKE
playground based course for elementary school children.
Course length: 2 hours |
Outcomes | Bicycle skills assessed on playground;
straight line riding coming to a complete stop, shoulder checking prior to left
turn. Also includes knowledge quiz.
Baseline & 3 month post intervention tests. |
Results | High helmet ownership and use at baseline.
No difference in observed behavior between groups at baseline
or follow-up. |
Study quality and conclusions | Small sample size.
Brief skills training program was not effective in improving
safe cycling behavior, knowledge, ot attitudes among 4th grade children. |
Author | Carlin, 1998 |
Study design and target population | Population based case control study.
Children 9-14 years; Melbourne, Australia
Cases: bicycle injuries seen at 2 major hospital emergency
departments. (ED) n=241
Controls:
RDD to select children who had bicycled in the past week.
n=232 |
Intervention | School based bicycle safety education:
"Bike ED", developed by Vic Roads.
Course covers safe riding skills traffic knowledge and skills,
and basic bicycle mechanics.
Topics taught in classroom, practice exercises in schoolyard
and supervised riding on local streets. |
Outcomes | Injuries received while riding a bicycle
that required emergency department visit.
Information collected by personal interview with child and
parent. |
Results | Cases= 148 Controls=130
16%of cases admitted to hospital.
Effect of Bike Ed program among participants and non-participants
for bicycle related injuries of all types ORadj=1.64, (95% CI .98, 2.8); for
boys OR=2.0, (95% CI 1.1, 3.8)
Multiple logistic regression used to adjust for sex, age,
SES, cycling, exposure time or distance.
Bike Ed program appears to increase injuries among those exposed
to program.
Negative effect stronger for low SES, younger children, and
for children whose family members do not cycle. |
Study quality and conclusions | Educational intervention dose NOT
reduce risk of bicycle injuries.
Possibly harmful effect of exposure to bicycle safety course. |
Author | Savill, et al, 1996 |
Study design and target population | Ecological study design.
School children (age 12) in the U.K. (N=1,974), 51% trained,
49% no training. |
Intervention | 8 bicycle training courses with curricula
meeting Transportation Research Laboratory criteria.
Courses had 4-8 separate 1- 1(1/2) hour sessions and included
training on public roads and playgrounds and off-road practice areas. |
Outcomes | Knowledge quiz, practical skills test,
cycling logs.
Children tested about 2 years after completing courses.
Group matched by age, sex, cycling experience and educational
achievement.
Biases in instructor abilities randomized by selecting children
from a range of primary schools. |
Results | Trained children more likely to score
a "safe" rating on skills test (p<0.001), score higher on knowledge
test (p<0.005) and more likely to own or wear a helmet (p<0.001) than
untrained children.
No difference found for cycling exposure. |
Study quality and conclusions | Good quality study.
Training children to ride safely has a positive effect on
their cycling practices at least 2 years post training.
Children trained with problem solving multi-stage course curricula
demonstrated best results. |
Summary of bicycle skills training studies
The studies reviewed above were unable to demonstrate a positive effect of bicycle
skills training for changes in observed cycling behavior or reduction in injuries.
Two studies reviewed above were unable to demonstrate a positive effect of bicycle
skills training for changes in observed cycling behavior or reduction in injuries.
The study by Savill and colleagues evaluated the long term effect of a number of
skills training programs currently used in the U.K. and was able to demonstrate
improvement in cycling skills, knowledge and helmet use in the group of children
who received training.
The monograph "Training Programs for
Bicycle Safety" reviewed 27 educational programs for children
and adults. The most comprehensive programs have all incorporated helmet education,
traffic rules, safety guidelines, and on-bike training into their curricula. Six
of these programs have been evaluated and shown to be effective in increasing participant's
knowledge and observed riding skills. There has been little evaluation of program
effectiveness in reducing injuries, or evaluation of long-term program effects.
The best study evaluating the effect of skill training on injuries (a population-based
case control study from Melbourne, Australia) indicated that this type of education
did not reduce injuries but appeared to actually increase injuries. This negative
effect was stronger among children whose parents didn't cycle, among low SES groups
and you nger children. The authors suggest skills training might produce harmful
effects in some children, perhaps due to inadvertent encouragement of risk taking
behavior or of bicycling without proper supervision.
Recommendations on bicycle skills training
There have not been sufficient evaluations of bicycle skills training programs
so recommendations are premature. Program effectiveness evaluations should compare
program participants to a comparable group that did not receive training. Outcomes
assessed should include number and types of crashes, the number and/or severity
of injuries, the level of helmet use, and the number of bicyclists in the area.
An ideal assessment should also measure the extent to which the learned program
skills are retained correctly and for the long term.
Recommendations for future research
Bicycle education programs should be thoroughly evaluated before their implementation.
Plans and funding for proper evaluation should be set forth at the beginning of
the program.
