Available data is examined for any changes in various traffic characteristics that could be ascribed to the recent fuel conservation measures. The data presented are in respect of accidents, casualties, vehicle speeds and travel times on rural roads, vehicle volume, mode of available data are pointed out. It was found that accidents and casualties had both decreased since the introduction of the fuel conservation measures with a greater decrease in casualties than the decrease in accidents. These reductions were accompanied by a relatively smaller decrease in general traffic volumes. The observed changes in speed and travel time distributions could explain much of the greater reduction in accidents than in total travel as well as the greater reduction in casualties than in accidents. It is concluded that the fuel conservation measures resulted in not only less travel but also in lower vehicle speed which was accompanied by a reduction in the accident rate as well as in the severity of the accidents. It is recommended that the speed limit of 80 km/h on rural roads be maintained for experimental purposes till at least the end of 1974.
