This scope covers the operational requirements of equipment for the identification of specific vehicles. Typically, such equipment might be used to detect buses at the approaches to a traffic signal intersection in order that a system of priority in traversing the junction may be accorded to such vehicles
This specification defines the requirements of the data transmission system, using multiplexing techniques (e.g. TDM, FDM or a combination of both), primarily based on cyclic transfer of data, to be used Area Traffic Control.
This specification covers the operational requirements, performance, and construction of epuipment which by means of inductive loop vehicle detecting equipment counts the number of vehicles which pass through a specified area
