Provide pavement markings <br />identifying the location of the detector. If bicycle <br />detectors cannot be installed, provide pedestrian <br />pushbuttons accessible from bicycle lanes. <br /> <br />28) Curb return radii and the configuration of <br />medians must be designed to facilitate pedestrian <br />crossings, while accommodating bus and major <br />freight movement. Primary design consideration <br />shall be for pedestrian movements.
