Abstract

This paper focuses on the rapid urbanization of Erbil City and emphasizes the importance of collecting and analyzing traffic flow data for a new residential project. When evaluating a new apartment in relation to the surrounding traffic, factors such as carriageway width, speed limits, and the number of lanes significantly influence traffic flow. The report is based on manual surveys conducted at 13 stations around the new apartments. The analysis reveals actual traffic flow during peak hours and proposes solutions to increase capacity from 7,766 passenger cars per hour (pc/hr) to 23,864 pc/hr. Key proposals include constructing a new underpass and roundabout at the Ankawa-40m road intersection, adding eight main entrance gates, and implementing minor changes to flow direction. The major roads are 10 meters wide, while the minor roads are also 10 meters wide, allowing a total traffic flow of 28,800 pc/hr. Curve fitting indicates that the optimal flow is 1,750 pc/hr per lane, with a free-flow speed of 26 km/hr and a jam density of 225 pc/km. The methodology also considers factors that reduce flow capacity, including carriageway width, lane width, and pavement quality. For instance, Section S1 has a carriageway width of 7.16m, while Sections S2 and S3 measure 19.28m and 16.03m, respectively. Wider roads can handle more traffic but may encourage higher speeds, whereas narrower roads can lead to congestion. These factors should be considered when selecting an apartment, as they involve balancing concerns about noise, commute ease, and safety.
