Peak-hour Factor (PHF; Capacity and Level of Service (LOS)Abstract
The core of highway design, planning, management, traffic control, capacity forecasting, and determining level of service is built on understanding the relationships between speed, flow, and density factors. The classification of urban streets into various street classes and speed-based levels of service categories is well defined in HCM 2010 and is particularly applicable in homogeneous traffic flow conditions. The Kurdistan Region is situated in northern Iraq, with Erbil serving as its capital city. The study aims to acquire speed data using a video camera and evaluate its usefulness in determining the speed ranges of LOS groups applicable to the current situation. Methodology that is used in this research is to apply HCM 2010 method for Shorash street in Erbil city. Also, two methods were utilized that are video photography and moving vehicles method. The speed ranges for urban streets in Erbil city context need to be defined according to demand on the roads because of high demand on this road. clarify is to acquire speed data using a video camera and how useful it is in determining the speed ranges of LOS groups that apply to the current situation. The Level of Service (LOS) obtained using both the video camera technique and HCS7 was the same, LOS = F. The results show, factors including traffic density, speed limits, the frequency of crossings, the existence of bus stops, on-street parking, roadside commercial activity, and pedestrian activity have a significant impact on service levels for main roads connected to 60, 40, 30, 100 m ring road in the city.
