The emergence of traffic and subsequently traffic congestion in urban road networks are increasing worldwide with the growing number of vehicles.In the worst case, traffic congestion results in excess delays, reduced safety and increased environmental pollution.As a result, to proffer effective solutions to the aforementioned congestion problems, a vast amount of literature offered fixed-time or traffic-response control strategies, each focusing on modelling traffic light controlled intersections.In this paper, a Timed Coloured Petri Net (TCPN) formalism is employed to model and simulate a multi-phase traffic light controlled intersection with an associated fixed signal timing plan using T-type junction located in Federal Capital Territory, Abuja, Nigeria, as a case study.Besides, the developed model is simulated via CPN tools while its validation is carried out on the basis of real traffic data measured by detectors positioned at each input link of the T-type junction under consideration.
