In India, the transportation industry has grown quickly, especially since the turn of the century. To connect diverse cities and towns, the Indian government is pouring enormous sums of money into the infrastructure and transportation sectors. This paper highlights on the need for cost effective road safety investments using \'rolling barrier\' systems which can redirect the deviated automobiles onto the right path and also prevent the overturning of vehicles. Road accidents are a result of the interaction of many factors, including the length of road networks, the number of vehicles, the population\'s adherence to and enforcement of traffic laws, etc. This study intends to assess the rolling barrier\'s efficiency and comprehend its crash cushioning properties, as well as how to rectify the vehicles\' running direction and the necessary barrier strength. The Rolling Barrier satisfied the ministry of construction and transportations, “Guidelines for Installation and management of road safety facilities”. Curved road portions, ramps, medians, and entrance or departure ramps in parking garages can all be safely protected by the Rolling Barrier.
A safety device called a Safety Roller prevents deadly collisions between vehicles and their occupants by both absorbing shock energy and transforming it into rotational energy. At locations where accidents involving automobiles are common, safety rollers must be installed. By absorbing shock energy, the Safety Roller can safely guide a car back to the road or bring it to a stop. The Safety Roller's distinguishable colour and self-luminescence will enable drivers to operate their vehicles properly A solution was created by a Korean company to lessen the severe impacts of guardrails and, perhaps, save lives. Around 1.25 million individuals per year pass away in road traffic accidents.
The railing can be used to direct a vehicle back to the road, slow it down until it comes to a stop, or allow it to pass the guardrail, according to the Federal Highway Administration. The guardrail can’t completely protect against the situations drivers may find themselves in. 5.04% of total roads in India comprise of National and State Highways and have cumulatively accounted for almost 54% accidents and 60% deaths in the country with the balance 94% of Indian roads contributing to 45% of road accidents and 39% of deaths.
The high number of accidents on highways are indicative of over speeding being the primary cause for such accidents. To minimize the no. of accidents (major damage to vehicles and human body) a company called ETI (Evolution in Traffic Innovation) designed “Rolling Barrier System”. Accidents are generally due to Over Speeding, Drunken Driving, and Distraction to the driver, Over Taking etc.
The majority of road users are aware of general safety precautions; however, accidents still happen because of other road users. To control road accident a small Korean manufacturing company came up with an innovative concept of roller barrier. Roller barrier contains ring of urethane material having a long pipe . The urethane ring is constructed to resemble an abacus and operates on the premise of converting shock energy into rotational energy. The barrier corrects the vehicle direction and prevents the vehicle from overturning and crossing the barrier.

B. Site Selection
NH48 Pune-Mumbai highway survey of selection site is done by the data available by NH 48 depending on that basis a small section of curve path is been selected as a project site for designing Rolling barrier having speed limit 100kmph Vehicle movement on the NH 48 were very high and frequently all sort of vehicles pass through so many accidents do occur the place is more curve therefore using roller barrier will reduce the accident rate. Survey of Project site there is a sharp curve in lonavla ghat. The categories of vehicles include tempo, auto, and cars, mini-truck, bus, motor cycle, tanker, truck and bus. The information available for accident studies is the HPMS (highway police Maharashtra state) lodged in the police station. The data from these records of last six years (2015 – 2021) were extracted from the HPMS record field under IPC no.
C. Survey and Collection of Accident Data on NH 48
National Highways are the arterial roads of the country for inter-state movement of passengers and goods. They traverse the length and width of the country connecting the National and State capitals, major ports and rail junctions and link up with border roads and foreign highways. The total length of NH (including expressways) in the country at present is 1,32,499 kms. While Highways/Expressways constitute only about 1.7% of the length of all roads, they carry about 40% of the road traffic. Accident details during 2015-2021 on this road section are shown. Accident data were collection is year wise form each police station records and then sorted out.
Working Principle: This long-standing customary system has shown to be subpar, as seen by the amount of deadly accidents on the expressway. The rolling barriers, on the other hand, help the vehicle stay on course and prevent overturning by both absorbing the impact energy and transferring it into rotational energy. As we can see in Fig. 1, as soon as a car deviates from the intended path and strikes the barriers laterally at any angle, the rollers rotate in response to the collision, converting the impact energy into rotational energy. In addition to lessening the intensity of the collision, the rotational energy helps move the vehicle forward rather than potentially smashing through an impassable barrier.
The characteristics of road accidents examined in this study include their overall number, their causes, their nature and types of injuries, the types of vehicles involved, and the times of accidents.
Depending on the accident's time, road accidents are primarily divided into two categories based on the time period. The first one is from 10:00 a.m. to 2:00 p.m., the second from 5:00 p.m. to 6.00 p.m. It is observed that more accidents take place during day time than night time. This may be attributed to a smaller cars during night.
Accidents are caused by either human error or a natural occurrence. There are many different kinds of obstacles to having unique qualities. The roller barrier stands out from all other types of barriers in a significant way. Compared to other forms of barriers, roller barriers offer more safety. In order to prevent accidents, the concept is to erect barriers on dangerous curves, steep hills, and national routes. From the previous discussion of barriers and test results, it is clear that roller barriers rank highly in terms of safety strength and outcome. Life is more valuable than the car, so when we ignore a roller barrier, we both save lives and prevent vehicle damage. Highways should strictly enforce the use of roller barriers. Future technology for managing and enhancing traffic safety will include roller barriers.
