REDUCTION IN PEDESTRIAN AND VEHICLE OCCUPANT FATAL CRASHES WITH DAYLIGHT SAVING TIME

Evidence from both Great Britain and the United States strongly suggests that an extra hour of daylight in the busier evening hours (British Summer Time and in the U.S., Daylight Saving Time) results in fewer serious and fatal crashes. In this study, the effect of daylight saving time was estimated from a model relating light level during morning and evening hours to fatal motor vehicle crashes. Light levels during these hours change not only with the time changes in April and October but also gradually as the seasons change. If light level can be used to predict motor vehicle crashes across both abrupt and gradual changes in light level, confidence in the estimate of the effect of daylight saving time on crashes is greatly increased.
