Purpose of Roadway Lighting
The general purpose of roadway lighting is to
provide improved visibility for the various users
of the roadways and associated facilities.

Objectives of Lighting
• To supplement vehicle headlights, extending the
visibility range beyond their limits both laterally and
longitudinally.
• To improve the visibility of roadway features and
objects on or near the roadway.
• To delineate the roadway ahead. To provide visibility of
the environment.
• To reduce the apprehension of those using the
roadway.

Induction
Electronic ballasts magnetically induce an electric field to create a current which circulates inside the lamp and excites the phosphorous to produce light in the same manner as standard fluorescent lamp.

Lighting Criteria
The criteria for highway lighting is in the Plans Preparation Manual, Volume I, Chapters 2 and 7. Horizontal Clearance for poles is in Chapter 2 Lighting Design Criteria is in Chapter 7

Plans Preparation Manual Volume 1
• 7.3.1 Design Criteria
The AASHTO Roadway Lighting Design Guide permits either the illuminance technique or the luminance technique to be used in the design of highway lighting. The luminance technique requires a more complex design process and knowledge of the reflective characteristics of the pavement surface used. These reflective characteristics change as the pavement ages and with variations in weather conditions. The Department has elected to use the illuminance technique for lighting design. The design values for light levels given by the AASHTO Roadway Lighting Design Guide are maintained values. The light levels given in this criteria have been adjusted and are listed as average initial foot candle.
