The "Foundations and Criterias" the Integration of Transportion Systems in Large Cities' Centres
Transport systems are a major part and a key component of the city and its centre، and directly affect its planning and urban design. Integrated transport systems are considered as a fundamental reason of easy and possible accessibility of people، merchandise and others، as well as they appear distinctly in developed cities' centres، and to achieve such a targeted integration، the main bases must be provided. This study is emerged owing to the absence of a clear vision in our local studies about the integration of transport systems in the centres of large cities to achieve easy possible accessibility in a smooth and easy method، and also appropriate to the actual need for transport in a sustainable way to meet the social، economic and environmental requirements، such that many cities have developed plans to address traffic congestions in a studied approach. Therefore، the research problem is "the lack of a clear and accurate vision of the levels and ways to achieve the integration of transport systems in the centres of large cities، including the city of Baghdad". The research hypothesis is "integrating of different transport levels، contributes to build a sustainable city، and it is a guaranteed assurance to meet the immediate requirements of mobility and accessibility without compromising our communities' comfort in the future". Integration levels and their different foundations are the means to achieve integration to create easy accessibility and provide a sustainable environment by planning for the time being، and adopting sustainable systems in future plans. Thus، the importance of this research comes from the importance of transport systems and the foundations of their integration and their impact on the city planning to match the need for transport easily and in a way that promotes the social، economic and environmental aspects.
