Abstract: Traffic congestion has become one of the major problems in the urban citiesaccording to the increasing number of vehicles in those cities, obsoletetechnologies used on the roads of those cities, inappropriate road design, andmany other reasons. So, that has urged the need for a more accurate trafficlight controlling system; one that will help in maintaining high stability atall levels of demand. This paper introduces a dynamic traffic light phase planprotocol for Single-Isolated Intersections. The developed controlling methodwas compared with four other methods and showed a good performance in terms ofreducing the average and maximum queue lengths, optimizing the given green timeamount as needed, and increased the intersections throughput (increased thegiven green time utilization). In addition, it maintained a good traffic lightstability at all levels of demand.
