    Combatting Red Light Running

    Being a volunteer activists for the National Motorists Association (NMA) is largely an unnoticed position, however there are rare times when someone contacts you out of the blue to speak with you on traffic related issues and ask for assistance. A local representative from Wavetronix, a Utah-based firm noticed an NMA mention in an Orlando Sentinel article on a recent Senate Transportation Committee meeting I attended in Tallahassee, FL. Over the phone, we discussed how red light cameras wouldn't have prevented the red light runner from crashing into her as she was driving through an intersection while her light was green. She sustained neck and back injuries and required several surgeries in the process of recovery. The runner hit her at least 5 seconds after the light had turned red, which fits a typical RLV (red light violation) crash profile.

    She explained that it was one reason that she joined Wavetronix, a company that manufacutures a variety of ITS (Intelligent Transportation System) equipment for transportation departments across the United States. Their latest product called Advance Detection has the potential to improve traffic flow and reduce intersection crashes by detecting traffic that is in the "dilemma zone", the area where you have to make a decision to either run through the light or attempt to slam on your brakes before the light turns red. When the device determines that vehcilce are in that dilemma zone and are traveling too quickly through the zone to stop in time, it will hold the light green for a couple of seconds for the traffic to clear. The device uses a 10 GHZ radar transmitter and a signal processor to provide the signals for the device to make that determination and then talks with existing traffic controllers that are pretty much uniform in the United States. The advantages of this unit is that it simulates having multiple traffic loops and can determine whether traffic is slowing or not through the "dilemma zone" prior to making a decision.

    The units are installed in several western states and they are attempting to get into the Florida market.

    This device has the potential to reduce the normal backups that occur at signalized intersections and to reduce crashes at red lights. As roads become ever more crowded, it will be likely to greatly improve traffic flow as well. More information on this and other units can be found on their website www.wavetronix.com.

    Re: Combatting Red Light Running

    Would a device like this be cheaper to install & maintain than a centralized traffic flow computer?

    I'm thinking that at rush-hour, traffic on the main road would get essentially a continuous green (because there'd always be someone in the "pink zone"), and people on the side street would never get their chance at a green.

    I can think of one obvious objection.... won't this encourage people who like to "push it" to bully on through if they know that by doing so, the light will remain green longer? Has that issue been addressed?

    Re: Combatting Red Light Running

    It is too early to say whether that issue has been addressed. My objection is that it doesn't address the issue of amber light timing, but by holding the light green enough to clear the dilemma zone, and if it stays clear for long enough, the other traffic will, by definition have time to stop....

    But will it stay "green" as long as people are still entering the intersection? Inother words, would it be possible to game the system by continuing to enter the intersection, kmowing that the light will "hold green" to accommodate you? If so, doesn't that mean jerks can (and likely would) use the system as a way to force their way through intersections and avoid having to stop at all?

    It will stay green, however, it detects gaps in the traffic more efficiently than regular loop detection systems and will switch the light more efficiently, however, I am going to ask the same question to the manufacturer.

    I'm sure you can guess the reason I bring it up... some saaaafety nag will use just that argument to oppose it. And to push cameras instead.
