Traffic Light Control For The Masses

uniformed1 writes "Eliminating red lights along the routes of their vehicles can give emergency response teams the few extra critical minutes that can save lives and property. A front page article in today's Detroit News details the emerging problem with a device that is now being made available to the public -- a traffic light changer. Originally intended only for emergency vehicles, the $300 MIRT (mobile infrared transmitter) emits an infrared beam that signals traffic signals to turn green and gives the vehicle the right-of-way. It is only a matter of time before self-centered drivers start using the devices widely to skirt traffic congestion, which is creating fears that chaos will ensue." Maybe if everyone had these, it would lead to smarter intersections.

  2. Ambulance drivers don't go full speed by JohnQPublic · · Score: 5, Insightful

    The only time an ambulance driver goes full-speed through an intersection with the siren screaming and cars breaking left and right is in the movies. In real life, they slow down and approach the intersection with all the care appropriate to one who's about to violate the traffic pattern. Because, after all, it doesn't help the dying guy in the back if the ambulance gets in an accident on the way to the ER.

    Why are these devices not illegal? Seems to me that the intersection should take a picture of the vehicle using the device... if there aren't flashing lights, send a ticket in the mail.

    The only problem there is how do you know which driver among the 20 approaching the intersection has the device? Sure, if you see someone with their arm out the window pointing a remote at the traffic light it's a no-brainer, but an IR transmitter peeking out of the front grill or behind some trinket on the dash would be impossible to make out.

    Just make it some enourmous fine... $25000 per offense or some such figure when the device is used for a non-emergency purpose. That way, the devices themselves aren't illegal (though I agree that they probably should be) but the uses are. You could, conceivably, drive your wife to the hospital when she's about to give birth, but you couldn't use it just because you're late for work.

    The lights in the direction of the emergency vehicle turn green so people can move out and away instead of blocking the intersection. I've seen people at regular 'dumb' intersections sit in front of a fire truck and block it because he thought he would get in trouble for running a red to let them through. Also, I'm not sure if it's lke this everywhere, but around here if something comes through such an intersection the light goes from green to red with no yellow warning at the exact same time the other direction gets the green. That sould defiately cause some chaos if ignorant drivers decide to get selfish.

    One thing people always forget is that speeding and runing reds rarely gets you there faster. People who dodge and weave through rush hour highway traffic are a whole 2 or 3 cars in front of me when I get to the off ramp. I've learned the timing of lights around my office and home so now I can actually get there faster by driving just few miles under the limit. Usually it's the impatient people that create traffic in the first place. The more that people obey speed limits the better the timing of intersections gets.

    1. Do what the military does, strobe the lights in a morse code fashion. Assign a seperate code to each city vehicle that needs to use the system. Any vehicle not strobing a proper code gets no joy.

    2. retrofit traffic light camera's to snap pictures of the traffic when the system is activated. Remove the infrared filter from the camera and the camera will easily and plainly show the vehicle that is attempting to open the intersection. You get a picture of the perp and his license plate, plus the light will be plainly visible to the camera. Perfect evidence for a court case.

    If the system is coded and someone attempts to copy the codes then they can prosecute them for hacking into a governemnt computer system.
    After all, the traffic lights are computer controlled, they should not be accessible to the public and if you hacked the system via the Internet it would be your nuts on the chopping block.

    I welcome every complete moron that buy's these to use them... just like the police radar jammers.

    As with any device that is in a legal grey area, judicious use is the key. Think of these things like stinkbombs in high school. If you are the ONLY one in the room where you use it, it will be more than obvious who is responsible. If you do use it in an auditorium with 500 other students around you, it is much harder to find out who is the culprit.

    If you are in a fair sized group of cars, you are pretty safe when using a radar jammer or device to change the traffic signal. Sure it may be illegal, but when the effort required to catch you makes in impractical to do so, the police don't even make the effort. How often does the office football pool get busted?

    PROBLEM; Light goes green.

    Design the device to make the lights go RED in all directions. Emergency vehicles can safely drive around the waiting traffic on the 'wrong' side of the road, because there's no oncoming traffic. There's no 'subtle' way for a non-emergency vehicle to use this type of device.
