This project developed and tested a new microprocessor-based switch system (Conservation Traffic Control Load Switch) which has a potential to significantly enhance the service life of traffic lamps by reducing the initial current surge in the filament coil. The prototype switch system was designed, assembled and tested in the laboratory. Tests showed that the system functioned satisfactorily in the signal cabinet, and used about 30% less electrical energy to operate the lamp. Additional operational and field tests were performed in collaboration with state highway agencies with satisfactory performance.
