Abstract
City center is exposed to many problems including the mixing uses, bottleneck in traffic and the inadequacy of the existing fabric for the current changes in the means of movement, therefore this paper studies the impact of the urban transportation system on the road network in the city center, in order to achieve a better environment. The paper focuses on analysis of the study area by making a comprehensive survey of quantification of trips generation as a result of these uses, and a survey of all the numbers of transport means and distribution to all regions of the study area, then the stage of traffic assignment to evaluate network connections to know the traffic level of service. Followed by a proposal for some alternatives can be applied to measure the impact on the road network as a result of buildings uses change and means of transport in the region. The paper is ended by recommendations that help to achieve the required balance resulting from the interactions between these uses and transport systems on the road network in the city center to reduce the pressure on them.
