ATAC Builds Relationship with the North Dakota Department of TransportationThe North Dakota Department of Transportation (NDDOT) strives to provide safe and efficient transportation to support the mobility needs of its residents and businesses. Several challenges greatly influence the transportation system in North Dakota, such as low population density, migration of state population to urban centers, and shortages in available transportation funds. These challenges are best addressed through enhanced decision making, supported by accurate data and state-of-the-art analysis tools. Technology, in the areas of information and Intelligent Transportation Systems, can also enhance the performance of the transportation system. Therefore, the NDDOT is committed to its partnership with North Dakota State University in supporting the Advanced Traffic Analysis Center. The NDDOT is using the ATAC as a resource for cutting-edge technical solutions, as well as an investment in the future of North Dakota, which will yield qualified engineers who can effectively operate the state's transportation system. This partnership has been and will continue to be a win-win relationship for the NDDOT, NDSU, and the entire region. System Collects Traffic DataThe 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 system 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 allows the ATAC to perform various research, 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, turning percentages, speeds, queue lengths, and incident occurrences. The system can be readily adapted to communicate with traffic controllers for vehicle detection. The TDCS is a mobile unit that can be set up quickly and without disrupting traffic. A self-contained power source allows the system to be deployed for up to eight hours without the need for personnel. In addition, the TDCS can operate during various lighting conditions and in non-ideal weather conditions. The TDCS consists of two video cameras and pan/tilt devices mounted on a 42-foot telescoping mast. The Autoscope system processes the video images based on user input and records the data. In addition the images are recorded using time-lapse recorders. All components are rack-mounted in a mobile cart, which allows for further analysis of VHS tapes in the ATAC laboratory when the system is not needed. ATAC personnel have used the system in the Fargo/Moorhead area for intersection data collection, work zone speech measurements, and pedestrian counts. Train detection analysis was also completed in Moorhead, Minnesota. 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 Kiel Ova at kiel@atacenter.org |
