The primary FOT objective was the implementation and performance evaluation of adaptive traffic signal control technologies including an existing second generation approach, 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, first generation UTCS-based control 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 utilized 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 andinstitutional issues limiting expected performance. Technical issues which limited SCOOTperformance included less than anticipated quality of existing communication and controllersystems; corresponding institutional factors included inconsistent project management due tostaff changes and delays due to contractual issues. Both SCOOT and a modified version of theVTDS are in current use in selected areas, with plans for system expansion.This evaluation report summarizes Task B of the three part evaluation project.
