Reboot Unresponsive Network Elements in Remote Traffic Signal Equipment Enclosures

Small problems with networked devices in traffic signal control enclosures can quickly escalate into huge traffic problems. When a sensor or signal timing device in a street corner traffic signal control enclosure crashes or becomes unresponsive and causes a traffic signal to malfunction the result is often a massive traffic tie up that quickly spreads in all directions. In cases like this, an immediate solution to the problem is mandatory; there isn’t time to wait for a service team to arrive on site. Fortunately, a network power switch can provide a means to deal with equipment problems in remote traffic signal enclosures immediately.

A typical traffic signal control enclosure can include a surprising assortment of different networked devices. From familiar devices such as Ethernet switches, to specialized devices such as inductive loop detector control systems and signal sequencing equipment. When any of these devices cease to function, the result is often a loss of communication with the equipment in the enclosure (in addition to traffic problems.) When a crashed Ethernet switch or other networked device interrupts communication with a traffic signal control box, system administrators can be left with no alternative but to send a tech team out to deal with the problem. Unfortunately, while the tech team is en route, traffic continues to back up as tie-ups continue to spread to surrounding streets and highways.

The best way to avoid situations like this is to make certain that the traffic signal control enclosure includes a network power switch that allows administrators to remotely reboot devices within the enclosure. Ideally, the network power switch deployment should also include a solution for out-of-band communication with the enclosure. Typical out-of-band management solutions include communication via secondary network, broadband or dial-up. When remote power control and reboot capabilities are combined with out-of-band communication, this provides system administrators with the ability to quickly reboot unresponsive devices in remote enclosures, even if normal network communication is not available.
