This report is another on the continuing study of speeds of vehicles on Indiana Highways. Observations of spot speeds were taken on interstate, four-lane and two-lane highways throughout the state during the months of February and March 1976. Analysis of the speeds showed the overall average speed for all vehicles was 56.8 mph. The overall average speed for passenger cars and all trucks was 57.3 mph and 55.6 mph, respectively. These overall average speeds are 0.6 mph, 0.5 mph and 0.7 mph less for all vehicles, passenger cars, and all trucks, respectively, as compared to the data collected in October-November 1975 (speed report No. 95).
