The school zone flashing beacons in Longview, Texas (pop 85,000) used a paging system to program school signals. Keith Covington, Traffic Signal Supervisor, determined the system “limited us, not only communicating with the clocks but monitoring the clocks”. ELTEC’s SYSTEM 3000 was chosen to centrally program, manage, and monitor each TC-3000 IP time clock (36 total).
When the SIMA software service was discontinued, remote communication and programming to Spot Devices’ school zones systems was no longer possible; nor was there a means for programming at the pole. For the MODOT (Missouri) Southwest District, ELTEC designed a cost-effective solution while salvaging as many parts as possible. Specifically, the cabinet, battery, charge controller, solar panel, and beacon were reused.
