Guidelines for Left-Turn Treatments at Unsignalized Intersections and Driveways

The objectives of the research are to develop guidelines by formulating a model, which determines the operational effects of left-turn movements at unsignalized intersections and driveways on the state highway system. These effects will be measured and estimated in terms of parameters such as roadway classification, traffic volumes, roadway speed, left-turning accidents, delay and excess fuel consumption experienced by through vehicles due to left turns.
