This paper proposed a traffic control system to eliminate vehicle stoppages at isolated signalised intersections. The paper has presented the theoretical analysis of the proposed min-max method, derived values for Vmax to Vmin, and set controls for alternating vehicle speeds at the two sides of the intersection. The results of the theoretical analysis were verified using discrete event simulation (DES) and compared to the conventional traffic light signals. Traffic modelling with DES allowed for deploying flow logic, animating traffic flow, verifying the non-stop functionality at the intersection, and estimating values for key measures of performance (MOP). Simulation results demonstrated the advantages of the proposed Min-Max method in eliminating stoppages at the isolated intersection, reducing traffic congestion, reducing vehicles delay, and improving vehicles flow. Other benefits from eliminating vehicles stoppages include a reduction in fuel consumption, air pollution, braking, and crash. The paper also addressed the possibilities and limitations of adopting the proposed system in controlling real-world traffic. The flexibility of the proposed system and the relatively low cost of needed control equipment encourage the applicability of the Min-Max system to replace traffic lights at isolated intersections. System deployment should be tested for real traffic and combined with proper safety measures. Further research can be directed to utilizing DES in incorporating measures for protecting pedestrians, handling arterial roads, coordinating adjacent intersections, testing the three-phase and four-phase signalling system, and assuring drivers compliance.
