Satellite supported traffic signal controller |
摘要 |
A local traffic signal controller (3) is interfaced to a satellite subscriber unit (10) to provide for centralized control of the traffic signals (1) controlled by the local controller (3). A central controller (7) provides central control and can download program control information to local controller (3). Dial-up access to local controller (3) is provided to central controller (7) with the subscriber unit (10). The resultant communication path may be utilized to provide for accessing information from the local traffic signal controller (3). Such information may include indications of lamp failures, traffic pattern information and other status or traffic related information.
