At a recent meeting the question came up “Do other States have automated reporting when roadside safety features are damaged?” Based on that, California DOT has the following four questions:
1. Does your State use devices that automatically report when roadside safety features are hit/damaged?
2. If you do, are these devices solar-powered, battery operated, hard wired, etc?
3. How do they communicate? (satellite, cell phone, etc)
4. Are the devices commercially available, if so, please provide a vendor name?
