SCOOT—An Update

摘要

In his January 1986 ITE Journal article "Research on the TRANSYT and SCOOT Methods of Signal Coordination," Dennis Robertson1 of the TRRL introduced the Adaptive Signal Control System SCOOT (Split, Cycle, and Offset Optimization Technique). His article explained how the British-designed system evolved from the TRANSYT method of optimizing signal plans. This article will discuss how the method has been developed and improved, and the extent of its application worldwide. The first United States SCOOT system controlling signals is in Oxnard, Calif., and a second soon will be installed in the City of Anaheim. This article will suggest how SCOOT may contribute to North America traffic management in the coming years.
