Traffic-Camera System Flops on Route 7
An obviously good idea that apparently still isn't supported by technology that actually works. The Wash Post story today describes the failure of a $500,000 high-tech traffic detection system along Route 7 in Northern Virginia that was supposed to detect the approach of traffic and change the timing of the lights to smooth the flow. Route 7 is a pretty awful drive but this system didn't work - the sun, says the lead VDOT official in Northern Virginia, created glare that kept the cameras from detecting the cars.

Even if they get the sensor problem fixed, timing the lights is no mean feat and will need to be dynamically rebalanced overtime.

No matter the best way carefully you can get getting some sort of pikalaina corporation, you are always possibly be billed a greater regular monthly attention for one pikavippi heritage particular pikalaina as opposed to in the event you purchased a favorable credit status.
