A platoon-based traffic signal timing algorithm for major-minor intersection types

This paper presents a platoon-based traffic signal timing algorithm that reduces traffic delays at major-minor type of intersections. The algorithm reduces traffic delays at intersections by minimizing the interruptions to vehicle platoon movements on the major roads. In this paper, the characteristics of vehicle platoons are discussed, including the key platoon variables and their mathematical distributions. Then the platoon-based traffic signal timing algorithm is illustrated with proposed platoon detector placement and signal control logic. Further, through computer simulations it is shown that the platoon-based algorithm provides better performance at major-minor types of intersections than conventional signal timing algorithms.
