SMART ROAD DIVIDER … SOLUTION FOR TRAFFIC CONGESTION. Shrikrushna V. Jadhav Student, Civil Department, RMD Sinhgad Technical Institute Campus, Warje, Pune, India – 411058. ABSTRACT Traffic is a major problem in the modern era with the increase in population there is increase in the number of vehicles, road users which end in congestion of traffic. The static road infrastructure is almost the same and unable to cope with changes like congestion, unpredictable travel time, delay and road accidents that taking a serious shape and due to this there is need to control the road traffic with help of traffic control optimizer. In spite of measures being taken to migrate and reduce traffic, it becomes major concerned faced by the metropolitan cities during the planning of cities it has emerged as one of the main challenges for developing cities. To find out appropriate measures there is a necessity of identify magnitude of traffic congestion. The construction of new road or widening of existing road is not feasible every time it will result in additional traffic congestion the total available space within the city for the construction of road, railway and other transportation are restricted. This study focuses on the implementation of movable traffic dividers to solve the traffic congestion problem in metropolitan cities.

INTRODUCTION: In today's world, population is increasing continuously as the rate of birth increases proportional to the rate of death due to advanced progress in medical science. This is a good thing but at the other side, we are still stuck on conventional energy resources for our daily energy needs. People tend to use personal vehicle instead of public transport system. There are many reasons behind this fact like failure of Public Transport System at users requirement, public system cannot provide service to any desired place, requirement to change mode of transport to reach particular destination which sometimes undesirable to the user. In developing countries like India due to lack of public transport system, people purchased personal vehicles. In 2015 registration of vehicles in India touched on all-the time high of 1.96 crores which means in actual almost 53,720 vehicles hits the road every single day in India.[1] Adjusted for the large population, India has less than 3.8km of road per 1000 people.[9]
When traffic is at only one side of divider there is a necessity to provide some extra space to the side where traffic is congested from another side having very light compared to congested side. At this situation, Movable Divider is required to do such action with the help of linear actuator for horizontal transverse movement to the road alignment. Components: 1. Divider 2. Sensors 3. Micro Controller 4. Linear actuator 5. Motor
As compared to increase in the vehicles per year, working of new road and implementation of solutions for heavy fresh traffic created by new vehicles is very less. The Ministry of Road Transport and Highways has fixed a target of 20,000 km for 2018-19 which is 25 percent more than 17,055 km awarded in 2017-18.[2] Condition of roads and their capacity is not enough compared to increasing daily traffic. Traffic congestion is the phenomenon where movement of vehicles get slow down or nearly zero which leads to increase in vehicular queuing and ultimately increases journey times. Traffic congestion does not only increase journey time but also directly impact on country's productivity. 40% productivity is decreases due to wasted time in daily traffic. [3] Traffic congestion classified in two groups namely Traffic at only one side of divider and Traffic on both side of road divider.
Fig. 2: Drawing of Smart Divider for model work. 1) Divider: Fiber Reinforced polymer is used to make road divider block. Road divider works to divide road area into two opposite direction to which vehicles are moving. Divider made up of using FRP material is lightweight and more durable than of concrete divider. This ultimately saves energy consumption to move it in lateral direction with the help of actuators.

2) Sensors: Sensors are used to detect density of traffic across particular road section where they are placed and thus they warn after predetermined traffic density to indicate congestion of traffic across that section of road. Ultrasonic sensor, Infrared sensor, Image processors can be used as a sensor. Out

CONCLUSIONS: The movable divider is capable of providing extra lanes with certain specified width to traffic congested side of road, by acquiring one lane of another side which carries light traffic at that time. Provision of lanes to a congested side totally depends on 'either another directing side of the road is also congested or not?' Thus by providing the suggested mechanism, we can use the width of the road to its full efficiency. The divider is said 'Smart' because it can detect the congestion through sensors and thus microcontrollers sends signals to divider to slide. So, basically movable divider is used to solve problems of traffic congestion on one side of the road with other side is free from heavy traffic. By doing this we can use road width at its full efficiency without widening of road which ultimately helps to preserve acquired land for other purposes besides of road from the unnecessary widening of road, which also leads to reduce cost of the widening of road, land acquisition and compensation. By using renewable energy sources, we can reduce the operating charge of the movable divider.
3) Microcontroller: Arduino Uno is an open-access microcontroller. AT Mega 328 is Arduino Uno type microcontroller having 14 pins with it. Programs are written in language of C and C++ for microcontroller. Microcontroller is used to control the movement of the divider and operate automatically with the help of sensors and linear actuators.

4) Linear actuator: Linear actuators are used below the road divider to move it laterally. Lead screw mechanism is used for movement of divider. Mild Steel is used for making Lead screw and stud as it is durable and strong. Grooves are provided at a certain distance around 2 – 3 meters in length of every section of divider. 5) Motor: Here D.C. motor is used for giving motion to the driving mechanism. Rotary motion of motor is converted into linear motion with the help of threads on Lead screw and Stud. DC motor's speed can be controlled over a large scale by changing given electric supply current. Test and Results: Table 1: Tests are performed on model of prototype. Traffic at side

DISCUSSION: When the traffic is at left, divider shifts to the right and vice versa at given distance generally width of one lane, but it is not capable to detect that congestion of traffic is reduced and flow becomes smooth at previously congested lane so it does not come back to center. This limitation of model is due to the limitations of microcontroller used but can be overcome by using and developing advanced microcontroller integrated with super computer having cloud system which automatically take decision about the position of further divider after detecting congestion of traffic at successively previous divider section alike signal system embedded with cloud system.
