ROLLING BARRIERS: TECHNOLOGY TO REDUCE ACCIDENTS ON ROADS MAINLY ON HILLY AREAS HORIZONTAL CURVES Harshit Saxena*1 *1Department

ABSTRACT The latest technology for the safety of vehicles on the roads curve is provided by the help of rolling barriers concept, providing rolling barriers on the intense curve helps in reducing many accidents of the vehicles nowadays, therefore rolling barriers proves to be the life saving technology for the drivers as well as passengers of the vehicles. In this paper, a study is performed to explain the need of rolling barriers in India especially on hilly roads horizontal curves, that is if rolling barriers are not provided on hilly roads intense horizontal curves, the vehicle can collide to simple boundary provided on those curves, resulting in breaking of that simple boundary and falling of that vehicle in the steep valley beyound the intense horizontal curve. The simple boundary can be made up of brick masonary, stone masonary, steel railings etc. Therefore rolling barriers can provide immense safety to the vehicle as compared to simple boundary provided on intense horizontal curves in hilly areas. In this paper it is aimed to replace the traditional boundaries provided on curves of hilly roads in India with rolling barriers. Keywords: Rolling Barriers, Technology, Steep Valley, Curves.

INTRODUCTION
Figure-2: Rolling barriers are installed on curve of hilly road.
According to survey conducted in India in the year 2016 the highest number of road accidents occur around 4,80,650 which contains 1,50,780 deaths. Report claimed by Indian express stated that there are 17 deaths on roads per hour in India. According to records 34.4% deaths took place on national highways, 27.8% deaths on state highways, 61% of deaths is due to overspeading the city Chennai lead in terms of accidents followed by Delhi. To reduce these accidents on Indian roads, we need to introduce new technology especially on intense horizontal curves of hilly roads which is termed as rolling barriers (rb). These rolling barriers can easily be recycled and they are also eco-friendly, these rollers are easily adjustable you can add or remove rollers anytime, rolling barriers are more strong as compared to ordinary traditional boundaries constructed at the horizontal curves of hilly roads as well as rb are more durable as compared to ordinary traditional boundaries, these rb also have less maintenance cost and can effectively replace traditional boundaries constructed at horizontal curves of hilly roads. Rolling barriers are also called as safety barriers, guardrails, longitudinal barriers, urethane rings barriers. Rolling barriers guide vehicles on their path and check vehicles from colliding with dangerous www.irjmets.com

Rolling barriers can be categorised in two types: 1-By the functions they fulfill. 2- How much they can divert a vehicle when it hits into the rolling barriers.

WORKING OF ROLLING BARRIERS.
Rolling barriers have flexible properties as well as semi rigid properties. The mechanism of rolling barriers is different from other normal barriers provided on the horizontal curves of hilly roads because of which rolling barriers provides more safety to vehicles and reduce the chances of road accidents. These rolling barriers are generally made up of urethane material, This urethane material has many applications in different fields nowadays and it has become a good choice recently by various product designers and manufactures because of its extraordinary physical and mechanical properties as compared to other materials. These rolling barriers converts the impact energy (shock energy) into rotational energy, when a fast moving vehicle collides the installed rolling barriers at the curves of hilly roads the rolling barriers will absorb some shock energy and the remaining shock energy is converted into rotational energy which saves the vehicle from falling into the deep valley beyond the curve of road and the vehicle after colliding to rolling barriers will be diverted to the turn provided in the forward direction because of its momentum which results in saving the life of driver and passengers. The shock energy is absorbed by four components of rolling barriers: 1- rollers of rolling barriers. 2- front rail of rolling barriers. 3- back rail of rolling barriers. 4- vertical post of rolling barriers which are provided to give strength to the arrangement.

BEHAVIOUR COMPARISON BY CONDUCTING CRUSHING TEST BETWEEN CONVENTIONAL OR TRADITIONAL BARRIERS AND RB=ROLLING BARRIERS
According to test-1 conducted by ksi korea it was observed that the conventional or traditional barriers experienced more damage as compared to rolling barriers ,therefore rolling barriers are more capable of replacing the traditional barriers provided on hilly roads of India. According to test-2 conducted by ksi korea it was observed that passenger car offers no damage to the rolling barriers while on the other hand slight damage was recorded when heavy vehicle (truck) collides the rolling barriers, therefore it states that the strength of rolling barriers is high as compared to traditional barriers provided on hilly roads of India.

IMPLEMENTATION OF ROLLING BARRIERS
Rolling barriers can be implemented in several places such as: 1- National highways. 2- Accident prone sites. 3- Parking lots. 4- Garages. 5- Apart from this it can also be wisely used on intense horizontal curves in hilly areas road like Nainital in Uttrakhand (India) etc. www.irjmets.com @International Research Journal of Modernization in Engineering, Technology and Science

CONCLUSION
India is a developing nation with lots of tourism places in hilly areas like: 1. Pahalgam, Jammu & Kashmir 2. Munnar, Kerala 3. Srinagar, Jammu & Kashmir 4. Shillong, Meghalaya 5. Kodaikanal, Tamil Nadu 6. Ooty, Tamil Nadu 7. Valparai, Tamil Nadu 8. Champawat, Uttarakhand 9. Yercaud, Tamil Nadu 10. Mussoorie, Uttarakhand 11. Nainital, Uttarakhand 12. Darjeeling, West Bengal etc. Tourism industry in India contributes widely for Indian economy and lots of people from all over the world visits India to experience the diversity in nature ,therefore the security of travelling should also be provided to these tourists, hence it becomes necessary to install rolling barriers at intense horizontal curves in hilly areas in order to provide safety from accidents or any miss-happening. Vehicles colliding to these rolling barriers will be safe as compared to vehicles colliding on simple boundary constructed at these curves therefore if we replace these traditional boundary walls with rolling barriers we will notice drastic change, that is less number of accidents on curves in hilly areas which will results in the increase of tourism and also consequently the safety of driver and passengers of vehicles travelling to hilly areas of India.
