The Minnesota Department of Transportation (Mn/DOT) sponsored the development and evaluation of the Adaptive Urban Signal Control and Integration (AUSCI) Intelligent Transportation System (ITS) Field Operational Test in downtown Minneapolis, Minnesota. AUSCI is a cooperative effort implemented by Mn/DOT, the Federal Highway Administration (FHWA), the City of Minneapolis, and private sector partners Fortran Traffic Systems Limited (Fortran) and Image Sensing Systems, Inc. (ISS). Traffic demands in the Minneapolis Central Business District (CBD) have changed dramatically over the past few years with the termination of I-394, addition of a 20,000-seat arena, and construction of other structures in the area. These changes have resulted in traffic patterns that vary significantly by time of day, change on a daily basis due to events and incidents, and change on a seasonal basis due to adverse weather conditions and construction activities. After a thorough review of the original system, an adaptive control strategy was selected to address the challenges posed by the significant variations in traffic volumes and patterns. |
