Replacing copper wiring with aluminum wiring for long runs and only using copper between the disconnect and the device is an emerging strategy UDOT uses that shows early success for deterring intrusions.
Security
Locate Intelligent Transportation System (ITS) Enclosures in Highly Visible Areas to Deter Intrusions
WSDOT locates cabinets and shelters in highly visible areas to deter unauthorized access and increase the likelihood of unlawful activities being reported.
Manage Access to Intelligent Transportation System (ITS) Enclosures with Electronic Key/Lock Systems
Electronic key/lock systems can offer an effective approach for managing access to ITS enclosures. Electronic locks are installed on all ITS cabinets and signal cabinets.
Label Junction Boxes “No Copper” to Deter Intrusions
To deter junction box intrusions, CDOT adds labeling/markings at junction boxes indicating “no copper” is present.
