Reboot Unresponsive Devices in Traffic Signal Control Boxes

When a network device in a traffic signal control enclosure crashes or becomes unresponsive, network administrators race to restore normal operation before traffic jams up completely. In cases like this, there isn’t time to wait for a service team to arrive on site; administrators need a means to correct the problem immediately, without the need for a physical service call. The most effective way to deal with a situation like this is to include a network power switch in the traffic signal control enclosure in order to enable administrators to remotely reboot networked devices.

Modern traffic signal control enclosures often include a variety of networked devices. When a street-side traffic signal control enclosure is opened, one can expect to find security camera controls, Ethernet switches, signal sequencing equipment, devices for managing inductive loop detectors and other networked elements. When any of these network elements crashes or refuses to communicate, signals malfunction and traffic slows to a crawl; this is completely unacceptable in an efficient Intelligent Transportation System.

WTI’s new NPS-3F15 series Network Power Switches provide traffic system administrators with a fast, secure, reliable means to reboot unresponsive devices in traffic signal control applications in order to restore normal operation and get traffic moving again. In addition to remote power control and reboot functions, the NPS-3F15 also includes advanced monitoring and alarm features that help system managers to keep on top of problems at remote traffic signal locations. The NPS’s monitoring and alarm features allow administrators to detect excessively high temperatures, unresponsive devices, power supply problems and other conditions at the remote site before problems arise, allowing a more pro-active approach to Intelligent Transportation System management.
