Abstract:
Evaluating the size and characteristics of traffic flow in emerging countries poses challenges due to the diverse range of traffic conditions present. The intersection is a crucial component within transportation networks since it significantly enhances the overall efficiency of the road network. The main objective is to precisely determine the saturation flow rate (SFR) at intersections in Faisalabad's urban area, considering the city's specific traffic challenges, such as the high number of two- and three-wheeled vehicles and issues with lane discipline. The average headway method is a widely recognized approach for accurately determining flow rate. It is commonly employed to estimate the SFR based on traffic data specific to intersections. The findings of this analysis demonstrate a Saturation flow rate of 1737 vehicles per hour per lane (vphpl), a quantity that holds considerable implications for the decision-making processes of traffic engineers and urban planners. This study highlights the importance of understanding the intricate traffic dynamics in Faisalabad to develop effective traffic management strategies that can effectively navigate the challenging road conditions. The interaction between regular vehicular motion and the unpredictable maneuvering of two- and three-wheeled vehicles that deviate from defined lanes has significant safety consequences. This research is noteworthy for its comprehensive methodology, which includes extensive fieldwork, video recordings, surveys, and observations to collect substantial data. The study at hand provides practical guidance to traffic engineers, urban planners, and policymakers by leveraging a comprehensive understanding of SFR and intricate traffic patterns.
