Capacity factor or cycle time optimization for signalized junctions: A graph theory approach

In this paper a method for setting traffic signals of individual signalized junctions is presented. Capacity factor maximization and cycle time minimization are considered as objective functions. The correspondence between cycle time and capacity factor is discussed. The influence of minimum green and maximum red constraints is analyzed. Once this correspondence is known, an efficient problem-oriented algorithm, based on a PERT-like technique, is proposed for the solution of the problem.
