A topic I'm eager to write about is the yellow dots on the pavement at intersections. You may recall my epic on pedestrian buttons, No Ifs, Ands or Buttons (and the follow-up supplementary post). Well cyclists have a way of activating the signals too, and what better place to describe it than the brand-new traffic control signal at Bronson and Arlington:
To recap the lowdown on ped buttons: when there is a traffic control signal with buttons, and there is a little yellow sign above the button, that means you must press the button if you want the walk signal to activate (though for some such intersections there might be some times of the day or week when the signal changes on a fixed timing whether or not the button is pressed).
