Traffic signals at signalized intersections are effective tools to safely control the movement of traffic through the intersections word-wide. The conflicts arising from movements of traffic in different directions are addressed by time sharing between the intersection approaches. The advantages of traffic signals include an orderly movement of traffic, reduce probability of accidents by minimizing possible conflict points, and an increased capacity of the intersection, while stopping delays are the major disadvantage. This paper presents a prototype traffic signal design of four virtual fixed-time signalized intersections that addresses a coordinated design system. The major movements are assumed to occur along the Northbound and Southbound, and their optimal coordination through these intersections is achieved by changing their split times, cycle lengths, offsets, and left-turn phasing types in order to reduce the average delay, average number of stops, and travel time. Intersection 1, 3, and 4 are assumed to have the standard four-approaches, while intersection 2 is assumed to be a T-intersection with three-approaches. The simulation is conducted using VISSIM to make the final selections of the timing parameters.
