摘要：	The City of Minneapolis has successfully operated a 725-intersection computerized traffic signal control system for over 20 years. Construction of major commercial facilities in the Minneapolis central business district (CBD) has increased the need for more effective traffic control. Discussions with other cities and traffic specialists indicated that traffic congestion problems could be addressed by installing a system with adaptive control features. Minneapolis entered into a partnership with the Minnesota Guidestar office of the Minnesota Department of Transportation (Mn/DOT) to request funding for the Adaptive Urban Signal Control and Integration (AUSCI) test project. The project was approved in late 1994. This paper discusses the features that are being integrated into the existing T2000C centrally-based system, as presented at the 1998 ITS America Conference, and explains the status of the project, which began construction in July 1997 and is scheduled to begin operation in the fall of 1998. The AUSCI project consists of the installation and test of adaptive system operation in a 65-intersection portion of the CBD area of Minneapolis to enhance the existing T2000C computer system operation. Version 3.1 of the Split Cycle Offset Optimization Technique (SCOOT) adaptive control software will be implemented. Video detection, which includes 138 Autoscope Solo video sensors, is being installed to support the increased need for real-time traffic flow information. Control inputs and traffic flow evaluation data will be captured from the machine vision system and logged on a data file server located at the system master site. In addition, nine pan/tilt/zoom cameras will be installed for video surveillance. The city will manage and operate the SCOOT/T2000C modified control system. Operation will cover the SCOOT test area and the 660 other computer- controlled intersections.
