Warrants for highway lighting will be based on conditions relating to the need for highway lighting and the benefits that may be accrued therefrom. Factors such as traffic volumes, speed, road use at night, night accident rate, road geometrics, and general night visibility are important considerations in the determination of minimum highway lighting justification. Warrants for highway lighting will also be based on economic considerations such as maximizing the location, mounting height, luminaire type, and wattage efficiencies. As is with our standard practice, travel speed, pavement markings, highway signs, or other traffic control devices will be utilized prior to the installation of street lights.
