Full Description
This Design Guide provides guidance on evaluating requirements for lighting the roadway to provide visibility for road users transiting through or adjacent to the work area. Criteria for determining the lighting requirements for the conduct of work within a work area are provided in National Cooperative Highway Research Program (NCHRP) Report 498, Illumination Guidelines for Nighttime Highway Work,1 and are not included in IES DG-26-16; except that the impact of glare produced by lighting within the area on driver requirements is considered.The stipulations and guidance provided in this document should be incorporated into any statement of work for nighttime road work. Furthermore, contractors should be required to adjust the work area lighting if problems are identified after installation, or when directed to do so by the infrastructure owner.
