I work for a local municipality and would be more then happy to speak with our transportaion division about your suggestion. I never thought of that use..who would have thought !!
My personal opinion at this point in the game is that the lack of patents ( which are still on the table ) is whats stagnating the compnay at this juncture in ITKG's development. Once they break free of the patents office they will open new avenues for devlopement. Correct me if I'm wrong, but isn't the majority currently released involving the plastenna and LED usage?
I will report back what our city says regarding the use of LED technology for stoplights.
