Now a days, each and everything in our life demands the characteristic of being real time. Traffic control is a challenging issue in our daily life and it always requires to be modified to cope with real time demand. Ongoing systems have limitation because these have fixed time interval for providing signal as well as non-systematic way of signal time manipulation which does not provide the flexibility to readjust the system according to the changing situation. More over choice of an appropriate algorithm is not suitable always to control the system with variety of time. Considering these facts we have proposed a traffic management system with a modified process scheduling algorithm. For the betterment of traffic management, we actually proposed a modified round-robin algorithm in this paper. To verify it’s appropriateness virtually, a simulation environment is developed in JAVA. We considered variety of input and calculated average waiting time, variance and standard deviation of waiting time as performance metric for selecting the most suitable scheduling algorithm. The performance of existing process scheduling algorithms and modified round-robin are evaluated and compared. Finally, the simulation results show that the proposed modified round-robin algorithm is better adaptable to design an intelligent traffic control system.
