The safety impact of a yellow bicycle jacket

Publication: Research - peer-reviewJournal article

Abstract

The hypothesis of this project is that the safety of cyclists can be improved by increasing their visibility in traffic. This is explored by testing whether or not a high-visibility bicycle jacket (colour and reflectors) will increase the safety of cyclists. The project has been carried out as a randomized controlled trial with 6,800 volunteer cyclists. After random selection, half of the group – the test group – got the bicycle jacket at once and promised to wear it each time they biked during a year. The other half of the group composed a control group that got the bicycle jacket after the closing of the project, i.e. after a year. The safety effect of the bicycle jacket was analysed by comparing the number of self-reported accident for the test and control group. The self-reported accidents showed that the test group had 38 % fewer personal injury accidents with other road users – so-called multi-party accidents – than the group who did not wear the bicycle jack-et. If one only looks at accidents between participants and vehicles, the difference is 48 %. The differences are statistically significant at 5 % level. In the test group, 37 % of the involved parties in an accident report-ed that they were not wearing the bicycle jacket or any other bright-coloured garment when the accident occurred.
