Ok, you are referring to 2 different things.
The loops are there and they work. It's just that Penndot doesn't know what they are doing so the ramp meters just became a 1.2 million dollar roadside attraction. I mean, why in God's name would you need them up near the turnpike where there hardly ever is a traffic jam.
Now onto the solar panel poles with the radar boxes. They are mounted at a 90* angle with the flow of traffic and mounted 45* pointing down. I higly doubt that is useful in gathering any kind of data, especially speed. To clock a speeder, state polic need to clock you while either coming towards them or away from them to gather a speed rating (Dopler effect). And, these lovely panelled headaches are on I-95 also. :rolleyes:
When I drove through the I-95 corrider in COnneticut a few years ago., they had a similar system set up where my detector went off every 1/2 mile. I had to turn the damn thing off.
Locals up there confirmed the radar boxes.
