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.
Guidance
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.
Small Wireless Facilities Mounting Installations Guidelines
Guidelines, including construction drawings showing allowable small wireless facilities mounting locations on multiple types of UDOT poles, indicate the conditions in which co-location on UDOT structures is not allowed.
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.
The 5 Rs of ITS Device Maintenance
PennDOT developed a document that provides general guidance for repairing, refurbishing, replacing, relocating, and removing ITS devices (FIVE Rs).
Visual Guide to Illustrate What Is and Is Not a Divisible Freight Load
IDOT has developed a visual guide (Guidelines for Overweight Permit Movements and Divisibility) to help enforcement and truckers understand what is and is not considered a divisible freight load to support consistency in enforcement and to help truckers avoid violations and unnecessary stops.
