In 2009 the second project phase has been launched to further develop 6th of October City, a three million inhabitant New Urban Community (NUC) close to Cairo. AS+P, in cooperation with Archplan Cairo, have been assigned to prepare the conceptual master plan and detailed master plan for the new city centre and the southern expansion areas. As one of the special competences of AS+P, the transportation network of the new urban areas has been developed in an iterative process in close coordination between urban designers and transportation planners. This approach funds the basis for a sustainable city development. The macro-scale planning of the conceptual master plan integrated considerations for all modes of public transport for the entire city. Furthermore, it defined the hierarchic road network and made proposals for various road cross-sections. The detailed master plan of the new downtown area along the central spine refined the results of the conceptual planning stage. Multi-functional urban boulevards and streets have been developed to ensure that the transportation infrastructure meets the expectations of a modern city centre as well as the traffic demand of the growing regional centre.
