Delay Function for Signalized Intersections in Traffic Assignment Models

Abstract

The consideration of delay at signalized intersections improves the accuracy of equilibrium flows obtained from traffic assignment models. This delay depends not only on physical specifications of the intersection, intersection signal timing, and traffic volume and its composition but on drivers’ behavior and specific traffic culture in each country. This paper proposes a delay function for traffic assignment models, which considers the special drivers’ behavior in Iran. Unlike the existing models such as the
