The process of improving and developing road networks and intersections in major cities are considered one of the most important processes. That must be follow by the relevant authorities in order for road networks to keep pace with the development witnessed by the transportation sector in all its forms. The decline in the road service level measured is the true indicator of a number of factors such as operational speed, travel time, traffic volume and density, and the suitability of the road for users and pedestrians. This study collected field information on traffic volume, traffic speed rates, and traffic density for area of the intersection of ALThawra Street with ALHurriya Street, using the counting and photographing method for peak traffic hours. An exploratory and cross-sectional engineering survey was also conducted on the road subject to the study. The data was analyzed using statistical and engineering software such as Excal and the AutoCad program as well as the use of GPS and Total Station for surveying operations of the study area in its current condition. Taking into account the entry and exit lanes by collecting the traffic volume for the intersection controlled by a traffic light at the intersection of AL-Thawra Street, the results showed that the service level for this controlled intersection was very low (F) as the delay times exceeded the time of the red traffic light cycle, especially during peak period. A roundabout was designed for this intersection with geometric dimensions that meet the specifications and diameters that are consistent with the area of the site and the width of the road to accommodate the design vehicle and traffic volumes that suit the current and future intersection. A roundabout with a diameter of 46 meters and a road of 10 meters was designed to suit and allow the maneuvering of the design vehicle- WB20 without any special or general material damage during the construction of the roundabout and traffic use for the road. ...................... Key words:.............. Intersections, roundabout, service level, traffic volume, traffic density, Al-Thawra Street and Al-Hurriya Street.
