DCE were appointed by Tecnicas Reunidas to perform traffic modelling and analysis for phase 2 of the FEED Zekreet project for Qatar Petroleum in Ras Laffan. The purpose of the study was to analyse the traffic during the constructions and operation of the facility. The road network included the movement of vehicles between Doha, via Khalifa Gate, and the development (external trips) and the movement of vehicles between RLIC labour camps and the development (internal trips). The traffic study identified any potential traffic related problems due to the new development and determined appropriate measures to mitigate the impacts of these problems.
