Road Safety Audit of Paliyekkara-Nenmanikkara Road

This project report presents a comprehensive Road Safety Audit (RSA) conducted on the Paliyekkara- Nenmanikkara road, a 4.1 km stretch prone to accidents due to its challenging geometry and high traffic volume. The study involved detailed surveys, including preliminary road assessments and traffic volumetric analyses, alongside laboratory and field tests such as Sieve analysis, Dynamic Cone Penetration (DCP) test, Light compaction test, California Bearing Ratio (CBR) test, and roughness measurement using MERLIN. These tests evaluated soil properties, bearing strength, and pavement conditions to inform remedial measures. The proposed solutions include optimized pavement layer thicknesses, a side drainage system, and culvert improvements, visualized using SketchUp software. The project aims to enhance road safety by addressing identified hazards and providing actionable recommendations for infrastructure upgrades.
