Study on Traffic Impact in Large Construction Areas Through Adjustment of Pavement Marking on Tha Chin River Bridge, Highway No.35, Samutsakhon Province

Abstract

Rama II Road serves as a crucial arterial route connecting Bangkok to southern Thailand, playing a significant role in freight transportation and interregional travel. Currently, this roadway experiences severe traffic congestion. To address this issue, the Bang Khun Thian – Ban Phaeo Elevated Highway Project (Expressway No. 82) has been initiated to alleviate traffic volume. However, the construction process necessitates lane closures and detours, exacerbating congestion. This study involves traffic data collection, including traffic volume, speed, and travel time, followed by an analysis comparing different road marking adjustment scenarios and their impact on the level of service. The findings indicate that modifications to pavement markings effectively enhance traffic efficiency within the construction zone.
