We got maybe a 1/4 inch of snow Saturday morning in the Herndon/Reston area. All is gone now except for splotchy bits in 100% shady spots. I haven’t been on that trail but everything else looks clear.
Apparently, there is no special trick to getting the signals to work. DDOT says that there is a problem, however, with the sensitivity of the signals: they are not picking up all bicycles. Their traffic engineers are aware of the problem and may supplement the loop detectors with some sort of video or infrared detection.
