A METHOD FOR ASSESSING THE IMPACT OF THE ENERGY CRISIS ON HIGHWAY ACCIDENTS IN TEXAS

This study to determine the effects of the 55 mph speed limit (and the resultant accident reduction) involved the initial determination of what information was available from the various state agencies, and the subsequent development of a regression model to forecast both fatal and injury accidents on a weekly basis with a separate analysis for weekdays and weekends. This aggregation facilitated the use of existing data, and it permitted consideration of the overall effect of the energy crisis on a time sensitive basis that allows the examination of essential and leisure travel separately. The high degree of uncertainity of general observations is noted, and it is suggested that inferences from accident data should take into consideration the inherent Poisson variability associated with such data.
