GTS developed a Traffic Impact Analysis and Traffic Control Plan for the construction phases of the New Murabba, a megaproject in Riyadh, Saudi Arabia, planned to include the Mukaab, which will be the world’s largest building by volume. The Traffic Impact Analysis evaluated the impact of construction traffic on the surrounding road network during the anticipated 5-year construction period. 

To support the analysis, GTS carried out site visits and collected 24-hour, 7-day Automated Traffic Counts (ATC) at five locations on the major roads surrounding the site, and collected Turning Movement Counts (TMC) at the five major intersections on the site’s perimeter. This allowed for an evaluation of level of service (LOS) volume-to-capacity ratio, and delays at the intersections as well as estimates of queue lengths at the construction entrance gates. Concurrently, GTS calculated trip generation and trip distribution based on the anticipated peak construction period. 

The report, prepared in compliance with Riyadh Municipality guidelines for traffic impact studies, included recommendations to mitigate LOS impacts as well as engineering and enforcement recommendations to improve traffic safety, such as adding merge lanes, consolidating access points, and utilizing traffic personnel at strategic locations to manage entering and exiting traffic at peak times.
