Four overlays are included with the TDC Ultra. These show how the keys
are used when you do the various studies other than Turning Movement
with the TDC Ultra.
Overlay #1 is used for Classification stud-
ies. One side shows the FHWA Scheme F
classes, and the other side is designed to
allow you to define your own classification
scheme. The overlay material allows you
to write on it with a pencil or water-based
marking pen.
Overlay #2 is used for Gap or Signalized Intersection Delay studies.
Overlay #3 is used for Saturation Flow Rate studies or Stop Sign Delay
studies.
