DCE were appointed by Gharnata Consultant Engineers to conduct a Traffic Impact Study (TIS) for a new car park at the existing Souq Wakif development in Doha, Qatar. A detailed development plan re-view process was carried out to check access width, parking lay-out, internal / external vehicle and pedestrian circulation, sight distance, road safety, drop off/pick up and service vehicles movement. Following TIS guidelines developed by the Ministry of Transport and Communications (MOTC), traffic was generated, distributed and assigned to the road network using PTV VISUM. A traffic impact assessment was done at key access roads also. The development is located in the central business dis-trict of Doha, which height-ens the importance of the project due to the high vol-umes of traffic in the area. An emphasis is placed on the layout of access points and nearby junction analysis for a project such as this in order to ensure adequate tie-ins to an already busy network.
