MAINTENANCE MANAGEMENT OF TRAFFIC-SIGNAL EQUIPMENT AND SYSTEMS (ABRIDGMENT)
A description is given of the 1984 update of Synthesis of Highway Practice 22, which was published by the Transportation Research Board in 1974. This abridgment summarizes the portions of the update that may be of most interest to road maintenance personnel. Evidence abounds from U.S. sources and those abroad that signal malfunctions are widespread and serious in their consequences. The problem is with the frequency of failure and the excessive time before a failure may be reported. Hardware malfunctions are estimated to cost Los Angeles drivers $3.6 million annually and to increase gasoline consumption by 2.8 million gallons per year. Specific problem areas include nonstandardization of equipment, overuse of sophisticated controller and detector configurations, inadequate inspection during installation, the use of low-grade components not suitable to the environment, insufficient quality control, inadequate maintenance capability, damage from power surges including lightning transients, and lack of funds for equipment replacement programs. The basics of legal responsibility and liability, including the elements of negligence suits, are also summarized and suggestions are given for reducing risk.
