Urban traffic congestion is a pressing issue in rapidly growing cities like Erbil, exacerbated by population growth, increased vehicle ownership, and inadequate infrastructure. This study evaluates traffic conditions on the Kasnazan arterial road (known as Erbil-Koya Road) using field data and VISSIM microsimulation. The analysis focused on peak-hour traffic, geometric road design, and Level of Service (LOS) metrics, revealing severe congestion (LOS F) with extensive delays, high emissions, and inefficient traffic flow due to blocked lanes, illegal parking, unsuitable speed bumps, and excessive access points. Four improvement scenarios were simulated: lane expansion, ramp implementation, driver behavior adjustments, and access point optimization. Results demonstrated that lane expansion and ramp installations significantly enhanced traffic flow, reducing delays by up to 93% and lowering CO emissions by 63%, while improving LOS to D or C. Driver behavior modifications and access point management also yielded moderate improvements.
The study underscores the need for integrated solutions combining infrastructure upgrades, behavioral interventions, and sustainable transport policies. Recommendations include unblocking and expanding lanes, replacing U-turns with roundabouts, and promoting public transit to alleviate congestion and reduce environmental impacts. These measures aim to enhance traffic efficiency, support economic growth, and improve urban sustainability in Erbil.
