An overview is provided of the institutional and technical issues associated with the evaluation of the federally sponsored "Anaheim Advanced Traffic Control System Field Operations Test." The primary test objectives were the implementation and performance evaluation of adaptive traffic signal control technologies, including an existing second-generation approach, the Split, Cycle, and Offset Optimization Technique (SCOOT), and a 1.5 generation control (1.5GC) approach under development. Also selected for implementation was a video traffic detection system (VTDS). The SCOOT evaluation was defined relative to existing control based on first-generation Urban Traffic Control System (UTCS) but using standard field detectorization rather than that normally associated with SCOOT. Furthermore, SCOOT was installed to operate in parallel to UTCS. The 1.5GC system was planned to be efficiently used to update baseline timing plans. The VTDS was planned for use as a low-cost system detector for deployment in critical areas. Both SCOOT and the VTDS were implemented with some degree of success, with technical and institutional issues limiting expected performance. Technical issues that limited SCOOT performance included less-than-anticipated quality of existing communication and controller systems; corresponding institutional factors included inconsistent project management due to staff changes and delays due to contractual issues. Both SCOOT and a modified version of the VTDS are in use in selected areas, with plans for system expansion.
