Abstract
A local traffic signal controller (3) is interfaced to a conventional pager (16) to provide for centralized control of the traffic signals controlled by the local controller. The central controller (7) may use the existing pager infrastructure (12) to provide for the transfer of program control information to local controllers. A two-way pager may be utilized to provide for the return of information from the local traffic signal controller. Such return information may include indications of lamp failures, traffic pattern information and other status or traffic related information.
