A number of examples are described where maintenance was given proper consideration in the development of design standards. These examples include the following: the use of galvanized signal and lighting standards; the non-use of plastic conduit where there is the possibility of mechanical damage; the use of multiple freeway lighting systems; the development of a numbering system for luminaires; Standard Specifications which require five days of successful functioning before acceptance of a traffic signal; and standards for controller cabinet location, 6 out of 8 of which relate to the technican. Other features relating to controller cabinets, the mofification of signals more than 10 years old, walkways for overhead sign structures, guarantees with bonds on completed signals, and training courses by manfacturers. Other maintenance/design team cooperative efforts include the minicomputer traffic signal controller; the review of electrical plans and specifications for construction projects, the assisting of technicians during the construction phase in the testing of the controller assemblies, and the Electrical Specification Committee at the state level.
