摘要：	The City of Minneapolis has successfully operated a 715 intersection computerized traffic signal control system for over 20 years. Construction of major business/commercial, sports, entertainment, and convention facilities in the Minneapolis central business district (CBD) has increased traffic volumes and the importance of effective traffic control. Discussions with other cities and traffic specialists indicated that traffic control problems could be addressed by installing a control system with adaptive control features. Internationally, adaptive control has been provided in a number of locations. Its benefits may apply to the urban situation in Minneapolis, but a number of questions remain. Concepts for adaptive control were presented to the Minnesota Guidestar office of the Minnesota Department of Transportation (Mn/DOT) for consideration. As a result, a test project was approved for Minneapolis in late 1994 under the title of the Adaptive Urban Signal Control and Integration (AUSCI) project. The AUSCI project consists of the installation and test of adaptive system operation in a 56-intersection CBD area of Minneapolis. Version 3.1 of the Split Cycle Offset Optimization Technique (SCOOT) adaptive control software was selected. New video detection will be added to support the increased need for real-time traffic flow information. Control inputs and traffic flow evaluation data will be captured from the video detection system and logged on a data file server located at the system master site. Minnesota Guidestar will manage the AUSCI project. Minneapolis will manage and operate the SCOOT/T2000C modified control system. Operation will cover the SCOOT test area and the 660 other computer-controlled intersections. The AUSCI project uses a unique approach to improving normal system operation by attaching the adaptive SCOOT module directly to an existing system. This approach allows adaptive and non-adaptive operation to be provided on the same network. Over 125 video sensors will be added to provide both SCOOT data and online, automatic data collection. Linkages also will be provided to the Trilogy system for information distribution. Challenges and opportunities that will be presented as this project develops include adding new software code to an existing computer system, licensing and legal issues associated with the operation and ownership of a mixed system, using a video data collection system for both control and evaluation data, managing a mixed adaptive/non-adaptive control system, providing staff to meet support needs, and operating SCOOT with video detection. It is likely that there will be additional items of interest to other U.S. urban cities. The AUSCI project will begin
