Abstract: In developing countries, like India, traffic is inherently chaotic and noisy. In recent years, with an ever-increasing rate of development, there has been equivalent multiplication in number of vehicles on roads. Nonetheless the amount of vehicles using the roads has increased, the road infrastructure has not changed. In general, road divider is used to separate the on-going and incoming traffic. There is equal width of lanes on either side of divider.
Since the total available space for the construction of roads and other transportation within a city are limited, there is a need for optimum utilization of existing resources like number of lanes.
Index Terms: Ultrasonic sensors, Arduino UNO board, Bluetooth module
The challenge encountered with static road dividers is that the number of alleys on either part of the street is consistent. Since the resources are confined and quantity of personal vehicles have been increasing, there are plenty of vehicles on streets.
This calls for finer employment of extant resources like number of paths accessible. Through this paper,
Traffic Intensity can be reduced
Traffic Congestion can be avoided

The objective of this paper is to scale down the span of journey during the peak hours and to avoid the traffic congestions and also to provide better and smarter solutions to the traffic problems. Figure 1 & 2 illustrates about the working and detection range of ultrasonic sensor.
In  Conventional traffic signal system is predicated on fastened time idea assigned to every aspect of the junction that can’t be varied as per varied traffic density. A while it’ll be not give sufficient time to pass vehicles as a result of traffic light time is pre outline.
In  Now a days traffic downside square measure increasing thanks to the increasing range of vehicles and also the restricted resources provided by this infrastructure. Because of this, there’s a desire to attend longer before of the signals.
In  India is that the second most thickly settled Country within the World may be a quick growing economy. it’s seeing exaggerated no of road congestion issues in its cities. Infrastructure growth is slow as compared to the expansion in range of vehicles, because of house and price constraints.
In  they propose a system for dominant the traffic signal by image process. The system can find vehicles through capture camera pictures rather than mistreatment electronic sensors embedded within the pavement.
One of the major problems being faced by developing countries is traffic congestion. To avoid this traffic congestion, we have proposed a system that is comprised of ultrasonic sensors, Arduino UNO board, driver gears, Bluetooth module. Ultrasonic sensors are used on either side of the divider to measure the traffic density. There are two dividers: normal and extended. Arduino board accepts inputs from ultrasonic sensors and processes the data to perform necessary action. When the traffic density is high, the extended divider raises above ground level and the normal divider flattens to ground position. When the traffic density is high, to alert the public about the extension of divider, a buzzer is used and to initiate the buzzer, a message is delivered to nearest traffic control room stated as Alert, divider is being changed. When the traffic density is normal, no action is performed. If the traffic density is normal then a message is delivered stating that Normal divider is up and the extended divider flattens to ground level to the nearest traffic control room. The functionality of proposed system is explained as follows:

Fig.5.When traffic is heavy on right side of road
In this paper, we have successfully designed and developed a demo model of Movable road divider using Ultrasonic sensors, in which the results are satisfactory. The traffic congestion data from the sensors is given to the nearest traffic control room using a Bluetooth module. The data from the sensors is automatically updated. But in real time traffic congestion can be in more than one direction, then also this module can be used by using image processing rather than the basic sensors.
