This research paper reviews a study on the impact of citizens' dependence on semi-total mobility on their own car in the absence of other means of transportation such as buses or buses, which greatly affects the road traffic capacity and the level of service for it. The study relied on manual count for all types vehicles, from cars, buses and trucks, and determining their proportions in the traffic composition at of the coastal road in Souq Al-Khamis region in Al-Khums City, where selected a peak hour , from 8:30 to 9:30 am, where the peak hour volume and peak hour factor, hourly volume, and the level of service and traffic flow rate were calculated . Is expected that when carrying out the vehicle count process, the percentage of cars very high 90%, due to the reliance in mobility on private cars, trucks 9% and buses1% . where modifi by deducting 15% of cars (1655 Passenger Cars), the value of the discount was (248 Passenger Cars), and have considered that there are small and medium buses that transport from Souq Al-Khamis to Al-Khums ,assuming the average of passengers ten . (248) divided by ten passengers as average, assuming that each bus transports Ten passengers, which is equivalent to approximately 25 buses (15 small and 10 medium). and the level of service and service flow rate of were calculated and compared with the existing situation that was calculated. Analysis of the results indicated that the level of service after of modify had changed to better, from D to C and the flow rate decreased, and this has a positive effect to alleviate traffic congestion.
