The Influences of Macroscopic Modeling of Traffic Dynamics in Urban Road Segments Considering Side Friction Influences: A Case Study

Urban road networks are essential arteries of modern cities, facilitating the movement of people and goods. However, efficient traffic flow management in urban areas remains a critical challenge, often compounded by factors like side friction. This research article presents a comprehensive macroscopic modeling approach to understand and incorporate the effects of side friction on traffic flow in the context of Nakuru City, Kenya. Nakuru City, like many growing urban centres, grapples with traffic congestion and associated issues, demanding innovative solutions for sustainable urban mobility. Side friction, a multifaceted factor influenced by various urban elements such as parked vehicles, pedestrian activities, and roadside infrastructure, significantly impacts traffic flow dynamics. This study employed a macroscopic modeling framework to capture the complex interplay between traffic flow and side friction in Nakuru City's road links. Through extensive data collection and analysis, coupled with advanced traffic modeling techniques, the research developed a nuanced understanding of how side friction affects traffic flow patterns.
