The Rolling Barrier (RB) system is an innovative longitudinal barrier that can be effectively implemented on curved road segments, ramps, medians, and entrance/exit ramps in parking structures. In 2015, Maharashtra, India, recorded 63,805 traffic accidents, with 54.2% involving collisions with longitudinal barriers. These incidents could be significantly reduced by installing safer barrier systems. A small Korean manufacturing company developed the RB, a novel design featuring continuous pipes encased in urethane rings, aimed at improving traffic safety.

This study evaluates the RB’s effectiveness in crash cushioning, directional vehicle correction, and required structural strength. Experimental tests were conducted using a 1.3-ton passenger car and a 3.5-ton truck on curved road sections. Results showed that vehicles maintained a parallel trajectory with the RB post-impact, with no structural failure observed during crashes. Further strength and safety performance tests were carried out using an 8-ton truck and a 1.3-ton car. The RB met the standards outlined in the Ministry of Construction and Transportation’s “Guidelines for Installation and Management of Road Safety Facilities.” Comparative analysis confirmed the RB's superior crash absorption and structural performance over conventional barriers.
