guineaProf. Ir. Dr. Riza Atiq O.K Rahmat has been involved in the revolutionary Urban Traffic Management System to overcome traffic congestion in Bandar Baru Bangi and Kajang. According to Prof. Ir. Dr. Riza, who is currently the Deputy Dean (Undergraduate Studies, Development and Internationalisation), Faculty of Engineering, this smart traffic controlling system is able to effectively reduce traffic congestion. This system has been employed at main intersections around Bandar Baru Bangi and Kajang Town for the past few years.

This smart traffic light uses a camera as a sensor, therefore, it really ”sees” the real traffic situation. Video images are captured by the cameras placed on high positions and the images are processed in order to gain the number of incoming vehicles, the length of the queue as well as to detect accidents. The information is later used to determine the optimum “green time”. Optimisation is done so by using genetic algorithm to minimize delay time. This means that the smart traffic system responds almost immediately everytime there occurs a slight change in the traffic pattern. It is done by using the total-disperse system. Thus, a fast response is achieved according to the traffic situation at a particular intersection.

During peak periods, it distributes the green time according to the ratio length of the respective queue. It also prioritises traffic flow accordingly. Test on site shows that the system is able to respond correctly within 120 seconds. Physically, the system consists of four basic components, namely the Smart Camera sensor for collecting traffic data, the Intelligent Controller for controlling traffic flows at an individual intersection, the Intelligent Coordinator for coordinating the timing of an individual controller with its neighbour and the Smart Traffic Advisor. The communication system is based on wireless Local Area Network to link up all local controllers. Among the awards received by this invention are a silver medal award in MOSTI’s Science and Technology Fair, Best Paper Award from Road Engineering Association of Malaysia and a Bronze Medal Award at Geneva’s Salon International des Inventions.
