CENTRAL AND COMPUTERIZED CONTROL OF SCHOOL-ZONE SIGNING
To help improve school-zone sign management, the Road Commission for Oakland County (RCOC) in Pontiac, Michigan, is working with a contractor to customize the Sydney Coordinated Adaptive Traffic Signal (SCATS) system that controls the 60 dynamic school-zone signs in their jurisdiction. Major changes to the SCATS system will include a customized user interface and a new communications setup. SCATS uses dedicated telephone lines for second-by-second communications; the school-zone adaptation will use dial-up telephone lines because constant communication is not necessary, and dial-up telephone lines are more cost effective. Communications with each sign will update the clock on a daily basis to insure that the signs will activate at the appropriate times. Planned school vacations and holidays can be put into a schedule, therefore deactivating the signs when school is not in session. Unplanned school closures, such as snow days, can be centrally input at the RCOC to stop activation of any individual school sign. Widespread operations should begin in September 1999.
