This Innovations Deserving Exploratory Analysis (IDEA) project developed and tested a new microprocessor-based switch system [Conservation Traffic Control Load Switch (CTCLS)] which significantly enhances the service life of traffic lamps by reducing the initial current surge in the filament coil. Depending on the voltage set point selected by the U.S. Department of Transportation, CTCLS can extend lamp life as much as eight to ten times. CTCLS also has the potential to conserve energy, will significantly reduce maintenance personnel's exposure to hazardous situations, and will significantly reduce traffic lamp maintenance expenditures. CTCLS's microprocessor is readily adaptable to Intelligent Vehicle Highway System (IVHS) without the need for retrofitting.
