UNENLIGHTENED - AN UNSUCCESSFUL ATTEMPT TO PROMOTE THE USE OF CYCLE LIGHTS AT NIGHT

The risks of bicycle riding are greatly increased at night, especially if the cyclist does not have lights. Over 13 winter weeks a community behavioural intervention promoting cycle light use was implemented in the city of Christchurch, New Zealand, at two tertiary educational institutions. A third location served as a control. Baseline data from inspection of parked cycles and street observation of cycle riders showed that about 60% of cycles were not fitted with lights and between 40% and 60% of cyclists rode without legal lights, with the percentages varying as functions of sunset time, weather, and time of night. At neither experimental location did prompting, an incentive competition, nor performance feedback increase the number of parked cycles with lights or increase the number of cyclists observed riding with lights. © 1991.
