Abstract: Traffic jam is one of the major problems in a densely populated mega city like Dhaka whereas its population and number of running vehicles are much more than its road capacity. Traffic signaling systems, inadequate manpower, narrow road spaces and overtaking tendency of drivers create pro-longed traffic jams. Due to traffic jam a substantial portion of working hours have to be left on streets which indirectly put adverse impact on economy and unavoidable road accident which results loss of lives. As the number of road users constantly increases, and resources provided by current infrastructures are limited. Intelligent traffic control system has become a very important issue. In this study based on Round Robin Scheduling Algorithm an automatic traffic control system is proposed. The main objective of this study is to reduce the overall waiting time of the vehicle at the cross junction point. For doing this a microcontroller is used which will make the drivers bound to follow the traffic rules by controlling traffic system that brings the result of decreasing the rate of accident, controlling crowd, lowering the tendency of road blocking etc. This approach can be applied in cross road junction which are so busy and the sectors those experience a great traffic load.
