Corvallis, OR, January 4, 2007 PTV America and Econolite have teamed together to provide the first software-in-the-loop (SIL) controller available to PTV Vision® clients. This new product is fully integrated into VISSIM, allowing for a seamless transition of the ASC/3® database from the hardware into the VISSIM interface. It also complies with NEMA TS2 and NTCIP requirements.

The ASC/3® controller offers additional functionality to the VISSIM user by allowing for a 16-vehicle and -pedestrian phase, 16-vehicle and -pedestrian overlaps and 8 configurable concurrent groups in 4 timing rings. Thomas Bauer, P.E., PTOE, Dipl.-Ing., President of PTV America, describes the development of the ASC/3® SIL Controller for VISSIM as “a milestone for the transportation engineering profession. For the first time, traffic engineers, transportation planners, and signal engineers can all work with the same toolset. This integration of multi-modal simulation analysis with actual signal-control bridges the wide gap between analysis and field implementation that is unfortunately still the current state of practice.” He adds, “While this new technology was first adopted in the academic world, I have no doubt that it will spread quickly into the daily workflow of traffic engineering."

Gary Duncan, Senior Vice President and Chief Technology Officer at Econolite, expresses his excitement "about the opportunity that the ASC/3® SIL represents for both the transportation research community and practicing professionals. [Now], microscopic simulation users will be able to easily and cost-effectively observe how individual or multiple intersections actually respond to the conditions being simulated."

The ASC/3® is available as an add-on for VISSIM 4.2. For more information about the capabilities of the ASC/3®, visit http://www.econolite.com/pdf/controllers/asc3.pdf
