Abstract
This report is the quarterly study of speeds of vehicles on rural Indiana Highways. Observations of spot speeds were taken on interstate, four-lane, and two-lane rural highways and interstate urban highways throughout the state during the months of July, August and September 1976. Analysis of the speeds showed the overall average speed for passenger cars was 58.0 mph. The overall average speed for heavy trucks was 57.1 mph. These were 0.7 mph and 0.3 mph lower for passenger cars and heavy trucks, respectively, than the results of June-September 1975 (Speed Report No. 94).
