Queue Surveys

TDC has completed hundreds of queue length and back of queue surveys using both manual and video-based techniques.
We most commonly use high mast video collection units (VCU's) to conduct queue length surveys.
In some cases queue length and back of queue surveys can also be undertaken whilst surveying the intersections with no need to deploy additional equipment.The VCU's can programmed to survey over multiple periods for one day or for multiple days as required.
