Layan Ministry of Housing (MoH) Complex is a +800 housing unit residential complex planned to be built in Al Dabab area (Dammam). This development will also include a mosque, commercial and office buildings, with their corresponding parking supply.
In order to identify the impact that this new development may cause in the surrounding road network, and suggest any improvement that could alleviate the anticipated problems, a Traffic Impact Assessment (TIA) was carried out. This TIA included traffic counts and other data collection, to better understand existing traffic and road network conditions on the nearby streets. The existence of a signalised intersection between two 3-lane highways added an extra complexity to this TIA.
Once the existing situation was comprehended, an Aimsun Base Model was created, to represent the existing traffic conditions, not only including the surrounding traffic network and the signalised intersection, but the internal traffic elements of the new complex, the entry/exit points and car parking availability. The Aimsun model was utilized to represent future years’ scenarios, taking into account forecasted trip generation and future traffic volumes.
Finally, once the problematic sections were identified, mitigation measures were proposed in order to improve the performance of the signalised intersection, complex surrounding and the overall road network around the new development to be built.
