 Figure 10D-3. Example of Pedestrian Gate Placement Behind the Sidewalk This figure illustrates an example of pedestrian gate placement 
              behind the sidewalk. The figure shows a post-mounted flashing-light signal with two 
              red lights shown mounted in a horizontal line and a red and white 
              diagonally striped automatic gate assembly. A rounded-top audible 
              device is shown mounted on top of the post. A white crossbuck sign 
              with the words "RAILROAD CROSSING" in black is shown mounted 
              on the post below the audible device and above the post-mounted 
              lights. The automatic gate is shown in the horizontal position to the left 
              of the post, extending across the sidewalk, curb, and roadway. The 
              gate arm is shown with 45-degree diagonal alternating red and white 
              stripes and three red lights along the top edge. The base of the post assembly is shown as a dimension of 100 mm 
              (4 in) MAX. thick. The distance from the center of the post to the 
              beginning of the roadway beyond the curb is shown as a dimension 
              of 2.1 m (7 ft) MIN. Back
