This paper proposes an improved traffic controlsystem by having dynamic time limits at the traffic signal intersections. The proposed system uses sensors to find the traffic conditions to dynamically control the traffic. Prevailing static traffic control system may block emergency vehicles such as ambulance due to traffic congestion. The proposed Efficient Dynamic Traffic Control System (EDTCS) has Traffic Control Unit (TCU), Monitor Unit (MU) and Road Side Unit (RSU). RSU contains RFID reader which reads the unique RFID code for an emergency vehicle and send it to MU. MU uses sensors such as proximity switch and RFID tags to get the count of normal and emergency vehicles respectively and sensed informationis sent to TCU. TCU receives the count of normal and emergency vehicles and changes the signal dynamically by comparing the count obtained from different lanes. The proposed EDTCS saves travel time and gives a special priority to emergency vehicles like ambulance.
