A thorough evaluatory study measuring the effect of the lower speed limit on the general safety record of the New Jersey Turnpike revealed that the 55 mph speed limit is not only reducing gasoline consumption but also the number of fatalities. The analysis took into consideration the new method of speed enforcement, public awareness of the energy crisis and its implications, and some other traffic operation related factors. For purposes of the study, the first 10 months of 1973 were chosen as the "before" period and the first 10 months of 1974 as the "after" period. Comparisions reveal that the number of accidents was reduced by 27 percent, and the accident rate by 18 percent, despite only a 19.8 percent reduction in vehicle miles of all vehicles which travelled on the Turnpike. The type of accidents and the degree of injuries and fatalities were also analyzed and compared.
