Use of Acceleration-Deceleration Lanes : Technical Paper

This research study on the use of acceleration-deceleration lanes will provide a factual background regarding traffic behavior as affected by acceleration and deceleration lane geometry. The purposes of this research are: 1) To determine the speed and lateral placement of vehicles on various designs of acceleration and deceleration lanes on highway type facilities. 2) To correlate acceleration and deceleration lane designs with traffic behavior and driver requirements and determine the acceleration and deceleration lane design or designs which provide the most efficient and safest operation. This paper deals only with the progress obtained to date in this research study. It describes the results obtained on two study locations - the Indiana Toll Road and Interstate 65 in the vicinity of the city of Lebanon.
