Like Illumination, ITS structures are a roadside obstacle and must be checked against the appropriate clear zone requirements to ensure that the proper safety treatment is provided when needed.

Many ITS devices require specific placement and configuration requirements to perform properly. However, accessibility to these devices must be factored in when determining the location. Adequate access must be provided within the State ROW for department-maintained ITS systems. Elements such as cameras, data equipment, cabinets, dynamic message signs, and ground boxes must be accessible by maintenance vehicles and maintenance personnel. Where practical, it is desirable for the ITS system to be accessed without disrupting existing traffic.

Sight distances must be checked for dynamic message signs to ensure that the structure is visible to motorists for the length of time necessary to properly comprehend the more complex messages and that they have adequate time to react to what the sign is communicating.
