The research project had two sets of objectives, one for advanced, or adaptive, signal control systems and one for control systems integration. Then they developed a framework for investigating integrated control system needs and met with jurisdictions throughout the Seattle Metropolitan area to discuss adaptive signal control and control system integration. Of the adaptive control strategies investigated, UTCS 1.5 and OPAC show the most promise for implementation in the Seattle Metropolitan area.
Local jurisdictions are interested in improved coordination and some degree of system integration.
The corridor traffic management teams that will be established should take up the issue of control system integration.
