Is there any way to detect the inductive loop, let's say 100 meters ahead?

Here in Utah I've noticed that most intersections now have cameras. I thought they were mainly for catching speeders. My neighor owns an electrical contracting company that installs most of the stop and go lights in the state. He said that the cameras now monitor and control the traffic signals. It's all software controlled. He also said that some community police departments have access to the recorded video to use if there is an accident at an intersection. He said that due to state laws here it cannot be used as a photo cop system. The state outlawed that years ago. -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU] On Behalf Of Robert B.

I always thought that was just a joke... If you are, it sounds to me like Californians are loooooooong past due for a tax-break. ----- Original Message ----- From: "David Schmidt" To: Sent: Monday, June 14, 2004 8:17 PM Subject: Re: [OT]: detecting emergency vehicles > Since a lot of intersections have cameras to catch red light runners=20 > (at least here in So.
