A technique is described for comparing the potential noise impacts of construction hauling for a number of project alternatives. The technique is used on a modification of the level weighted population method to account for the duration of the hauling activity on the various haul route links; the resultant descriptor is termed Level/Duration Weighted Population (LDWP). A complex microcomputer spreadsheet was developed to facilitate data entry and calculation of LDWP for a base case and each study scenario, as well as a relative change in impact (RCI) over the base case for the scenarios.
