Traffic Data Collection System
The Traffic Data Collection System (TDCS) was designed and developed by the ATAC as a state-of-the-art data collection system and surveillance unit. This unit is capable of collecting detailed traffic data and can support Intelligent Transportation System (ITS) applications, such as freeway incident detection. The TDCS is a tool that will allow the ATAC to perform various research benefiting our customers, from video detection applications to work zone management.
The Autoscope Wide Area Video Vehicle Detection System developed by Image Sensing Systems Inc., is the core technology behind the TDCS. Autoscope collects traffic information such as volume, speeds, queue lengths, and incident occurrences and can be readily adapted to communicate with traffic controllers.
The TDCS is a mobile unit that can be set up quickly and without disrupting traffic. It is equipped with a power source and can be deployed for up to 8 hours without the need for personnel. In addition, the TDCS can operate during day or night and in non-ideal weather conditions such as rain or snow.
The TDCS consists of two video cameras and pan/tilt devices mounted on a 42-foot telescoping mast. The video images are fed into the trailer where the Autoscope system processes the signals and two VHS recorders tape the images. All of the components are rack mounted in a mobile cart, which allows for further analysis of the VHS tapes in the ATAC laboratory when the system is not in use.
ATAC personnel have used the system in the Fargo/Moorhead area for intersection data collection. Future applications will include train detection analysis in Moorhead and data collection for the NDDOT and F-M Council of Governments.
We are currently evaluating the video detection system and comparing the performance to traditional data collection devices, such as tube and magnetic counters. Future studies will include analysis of other video detection devices. For further information on the TDCS, contact Ayman Smadi at ayman@atacenter.org
