SPEED TRENDS ON INDIANA RURAL INTERSTATE HIGHWAYS. TRAFFIC RESEARCH REPORT

This report is a comparison and analysis of speed monitoring sessions made exclusively on rural interstate highways in Indiana for calendar years 1983 through 1990. All data were obtained from locations that have been exempted from the 55 mph speed limit. The results of this study show that all vehicles on all Indiana rural interstate highways had an average speed of 65.8 mph in 1990. This is 0.2 mph higher than the 1989 average speed of 65.6 mph, and 1.8 mph higher than the average speed of 64.0 mph during the 1988 calendar year. During 1990, cars had an average speed of 66.7 mph, short trucks (21-45 ft) 62.8 mph, and long trucks (46-99 ft) 62.7 mph. Study results show that 85% of all types of vehicles on all rural interstate highways were traveling at or less than 72.5 mph in 1990.
