Pak German Engineers successfully completed project of road safeties and installation of traffic signals with The Urban Unit (Government of the Punjab) at eight locations of Lahore, for Metro Bus Transit System. Current SCATS (Australia) compatible UTC controllers were installed at Firozpur road project of widening from Nishtar to Shahdara. These controllers had interlinked intersections with the centralized control room located in Aarfa Kareem IT Tower.
VVD-based systems can be implemented in various ways, such as time-of-day scheduling or real-time adaptive control. They can also include additional features such as emergency vehicle preemption, which prioritizes emergency vehicles through the intersection by changing the signal timings.
