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 capacity. Faulty 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 paper a microcontroller based Traffic Control System is introduced which will make the drivers bound to follow the traffic rules by controlling traffic system, decreasing the rate of accident, controlling crowd, lowering the tendency of road blocking etc. This plan can be applied in cross road junction which are so busy and the sectors those experience a great traffic load. Important cross road junctions of Bangladesh are Science lab junction; Shahabagh junction; Gazipur Cross junction; Shapla Chottor, Motijhil etc. Moreover this system can be applied in 35 points in Bangladesh in an effective way. In this system steel barrier is used to control traffic system which can be closed or opened by using microcontroller and a definite time period is needed to be set in microcontroller. This process is similar to the traffic light system used in mega city of a country but the main difference is in this system, drivers are bound to maintain the traffic rules. Thus this real-time technique can be able to solve the problem.
