Traffic control method is an interconnection of sign devices positioned at road intersections, pedestrian crossings and different locations to manage competing flows of traffic. This work provides a novel idea and application procedures of priority and round robin scheduling algorithms. These algorithms methodologies are combined and a new hybrid automatic traffic control mechanism is proposed for efficient traffic and transportation management systems. This mechanism is necessary and it may be applied to modern cities wherever particular paths have more traffic jam compared to other paths of signal and wherever equal or normal traffic. This proposed hybrid approach applies priority scheduling concept to specific paths which has more traffic, on the other hand, this hybrid approach uses round robin scheduling concept for normal traffic signals. This mechanism is well suited for controlling the traffic of modern and old cities,both preplanned and not preplanned before construction. Some general conclusions and promising future research topics are also provided.
