To get it out of the way I am quite aware they are illegal in most places.

Infrared cameras detect a certain frequency of flashing and then change the appropriate light to green while stopping all other traffic. Has anyone have any experience with them or know someone that has used one? Of course not all lights are equipped with these cameras but I come across several everyday.

There seems to be quite an aftermarket for them. They are fairly simple in design. I have seen a few schematics for them and my next free time project is to build one.

People talk about radar detectors without any problem. People constantly talk about going over the speed limit and thats never an issue. Many illegal things are discussed here.

Frankly I don't think it should be legal for traffic lights to unnecessarily waste my time. Why should I have to sit at a red light and wait for imaginary cars to turn on their green arrow while I sit there and wait? Or how about sitting at a red light for 5 minutes while absolutely no other cars are going through the green light in the perpendicular direction? Timed lights were a good idea 80 years ago. If the state truly doesn't want people to break the law then they would address these issues with traffic sensors to properly manage the flow of traffic. In reality they don't care because they make money off of people breaking the law.

I think I'll do some research on this.

MIRT is the common acronym used for the device.

I found a fairly well written DIY, you've probably read it yourself. I'm not too familiar with schematics so it will probably be a bit of trial and error for me. Most of the parts are easily purchased at an electronics store and the IRD array can be purchased online for about 12 bucks.

Yes we have read the same one. Radioshack should have most of the components except for maybe the timing chip. My only caution would be traffic MONITORING cameras. They are mainly CCD and if an operator happens to be watching they will see the strobe.

Yes, I'm aware that a CCD will pick up the IRD pulse. I'd probably build it for fun just to see if I can make it work more than anything because there aren't many places around here where I could use it safely. Looking at the built model, they have installed a red LED to visibly monitor the frequency of pulses but the red LED isn't listed on the parts list. Am I missing something?

Radar detectors are not against the law in many states. Everyone seesm to have a ***** about something in traffic management really.

Yes, everyone does have an issue with traffic management for good reason. If money was spent properly we would all have "smart" traffic grids. Think of all the time and fuel that could be saved over time if there were no unecessary waiting at lights? The technology to accomplish this is decades old. I would rather have a smart grid than a smooth road.
