Impact of Side Friction Parameters to Road Performance, A Study of Road Side Activities to Jend. A Yani Road, Purbalingga
Traffic flow on city roads is greatly affected by side friction elements, like parking on the street, pedestrian crossings, and non-motorized vehicles (NMVs), mainly in areas with mixed traffic. This study looks at these effects on Jenderal A. Yani Road in Purbalingga, Indonesia, which is an impor...

| description | Traffic flow on city roads is greatly affected by side friction elements, like parking on the street,
pedestrian crossings, and non-motorized vehicles (NMVs), mainly in areas with mixed traffic. This study
looks at these effects on Jenderal A. Yani Road in Purbalingga, Indonesia, which is an important industrial
route that links key manufacturing sites and sees a lot of vehicle and foot traffic. The goals of the research
are to (1) find the side friction factor that most impact vehicle space mean speed (SMS), (2) use multivariate
regression to understand the link between side friction and SMS, and (3) determine which traditional traffic
flow model—Underwood, Greenshield, or Greenberg—best fits the observed flow patterns in mixed-traffic
situations. Early results indicate that stopped vehicles are the biggest friction element that lowers SMS,
while pedestrian crossings and NMVs also lead to delays during busy times. The Underwood model, which
shows how speed decreases exponentially with increasing density, is the most accurate for depicting traffic
dynamics on Jenderal A. Yani Road, with a critical density of 9.75 vehicles per km suggesting the start of
congestion. These findings are useful for creating plans that improve traffic flow in urban-industrial areas.
By addressing side friction and using the right traffic models, the research aids in developing data-informed
approaches to enhancing the Level of Service (LOS) on roads with high friction, especially in developing
nations facing similar traffic challenges. This work helps in managing urban traffic by laying the
groundwork for planning that accommodates mixed traffic and lessens congestion. |
