Traffic dynamics of multiple paired U-turn slots

Abstract

A particular road configuration involves multiple U-turn slots. We show the conditions needed to construct the same scenario using a system of paired U-turn slots as the building block. Clogged states are determined for different separation distances between opposing U-turns. For the same distance travelled, a car on a road with less U-turn slots will spend less time than one on a road with more slots. The latter road configuration is only more favored for cars that make a turn early.
