Traffic Issues and Mitigation Measures at Vytilla Junction, Ernakulam District: A Comprehensive Study

Vytilla Junction, located in Ernakulam District, Kerala, India, is one of the most critically congested traffic nodes in the Kochi metropolitan region. Serving as the primary convergence point for National Highway NH-66, major urban arterials, and the Vytilla Mobility Hub—a multi-modal transit terminal integrating road, metro rail, and water metro systems—the junction experiences Level of Service F (LOS F) conditions throughout the day. Despite the construction of the Vytilla Flyover intended to decongest NH-66 through traffic, surface-level congestion persists due to severe turning movement conflicts, constrained carriageway widths under flyover piers, unregulated bus stoppages, and unmanaged pedestrian flows. This paper systematically analyzes the existing traffic problems and proposes a phased set of mitigation measures rooted in Transportation Systems Management (TSM) principles. Key proposals include a one-way circulatory looping system to eliminate cross-traffic conflicts, selective geometric reconfiguration within the existing Right-of-Way (RoW) without land acquisition, signal phase optimization, dedicated bus bay provision, and multi-modal pedestrian safety infrastructure. The study demonstrates that these integrated engineering and management interventions are capable of significantly improving traffic throughput, enhancing pedestrian safety, and upgrading the Level of Service at this hyper-complex urban junction.
