OverviewPlease note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Marshalite is a form of rotary traffic signal that was designed by Charles Marshall in 1936. It consists of two rotors pointing at coloured sections that denoted whether traffic in either direction should proceed, prepare, or stop. Variations exist for pedestrian crossings with additional text instructing crossers to Walk or Don't Walk. The last Marshalite to exist before they were removed in the 1970s was along the Nepean Highway, in Victoria, Australia. A similar system was proposed in Germany in the 1950s, and while shown in publications, the signal does not seem to have been put into use.
