Some fine comments here. The no-road markings/traffic lights/signage experiment hails from the Netherlands, of course, where they've had great success with similar schemes. Everyone: motorist, pedestrian, cyclist, stays on the move, albeit with a bit of consideration for one another. There is no more of the cork-from-a-champagne-bottle dashes from traffic lights brought on by unecessary red signals, as noted by *bob*. Get emailing!
