Abstract
The study involved an evaluation of reversible lanes as a method of increasing traffic flow. A unique feature of the system was allowing left turns during the period of reversible flow, which meant that the left-turn lanes had to be moved and the signal displays shifted during operation and without interrupting traffic flow. The evaluation involved a comparison of data taken before and after installation of the reversible lanes. Types of data included delays, volumes, accidents, speeds, traffic conflicts, fuel consumption, and environmental factors.
