TRAFFIC SPEED REPORT NO. 93
This report is another on the continuing study of speeds of vehicles on rural Indiana Highways. Observations of spot speeds were taken on interstate, four-lane and two-lanes highways throughout the state during the months of May and June 1975. Analysis of the speeds showed the overall average speed for passenger cars was 57.6 miles per hour. The overall average speed for heavy trucks was 55.5 miles per hour. This was about the same overall average speed for passenger car and for trucks, as compared to the data collected in June-September 1974 (Speed Report No. 92). No trend of increase in travel speeds is as yet apparent under the 55 mph maximum speed limit.
