Lighting Fundamentals for Nighttime Highway Construction
Nighttime construction is becoming common on highway construction projects. Today work on urban and high traffic volume highways is routinely scheduled for nighttime. Although the frequency of night projects is growing nationally a variety of experience levels exist from state to state. While some State Highway Agencies have been performing night construction for several years and others are just considering it as an option. The main motivation for performing highway work at night is to avoid the periods of day time high traffic volume which are common on many of our roads. Working at night when traffic levels are reduced reduces construction caused delays to motorist traveling through the construction area. Additionally, the construction process may benefit from the shift to nighttime. Material deliveries such as concrete or asphalt materials for paving operation are likely to be more efficient without the daytime congestion problems. However, constructing a project at night presents many new management challenges. Quality, safety and cost remain important concerns. Quality management procedures and safety practices that are effective for normal daytime construction may not be appropriate for the nighttime environment. Highway work zones typically are faced with a higher percentage of impaired drivers at night than in daytime. There are human factors considerations when placing workers on a night shift. Lighting of the work area is directly related to both safety and quality issues and is critical. The feasibility of nighttime highway construction projects has been well demonstrated. Many projects have been performed safely and with superior quality. Nevertheless, it is clear that managers undertaking a nighttime project must have an understanding and mastery of a completely new set of technical and management concepts. This paper summaries the results of several research initiative focusing on the lighting aspects of performing night time construction.
