A master's thesis in the College of Engineering at the University of Basrah discussed (a study of traffic congestion and its impact on the structural design of the roads leading to the campus of the University of Basrah, Bab Al-Zubair) The thesis presented by the student Eman Ali Taleb dealt with determining the level of service (LOS) for a multi-lane road through the density, which is calculated Divide the flow of each lane by its velocity. Traffic data and required engineering data are collected through field surveys, The total traffic volume of the study sites was calculated as follows: First, a A field survey using cameras on the highways leading to campus, and I knew the data Obtained as "Mobility Habits" Then a questionnaire was conducted about the transportation habits of faculty members, staff and students in the Bab Al-Zubair College complex. A vehicle analysis program using the models was also created Trained on the (YOLO3) algorithm that determines the type of vehicle (car, bike, truck, bus), calculates the number of these vehicles, and calculates the speed of each vehicle. During this study, a program was used (SPSS), a statistical program, to analyze the questionnaire, and (HCS) program was used to assess the level of service On multi-lane highways. With the help of (HCS, LOS) software was evaluated during the morning and evening peak hours on Baghdad Street and the roads leading to the university campus. The purpose of the thesis is to analyze and evaluate the level of LOS service on the road surrounding the university campus. The thesis made two suggestions. The first is to change the course of students on Baghdad Street by establishing parking lot on Al-Zubair Street towards the southwest, with the addition of one lane towards the west from Baghdad Street The other proposal is to construct a garage in the northeast direction. Zubair Street.
