Traffic speed report No. 104

This report is another in 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 January-March 1978 quarter. Analysis of the speeds showed the overall average speed for all vehicles was 58.4 mph. The overall average speeds for passenger cars and all trucks were 59.0 mph and 57. a mph respectively. These overall speeds when compared to the results of the October-December 1977 quarter (Speed Report No. 103) indicated little change. Average speeds obtained were very similar for the two periods - 0.3 mph less for all passenger cars and 0.4 mph less for heavy trucks for the most recent quarter.
