Abstract:The purpose of this project was to develop a random sampling plan for use in selecting segments of the secondary highway system for evaluation under the Department's PMS. The plan developed is described here. It is a simple, workable, random sampling plan that will select a 5% cross section of secondary roads on a per county basis and also yield condition rating forms for each roadway section. The condition surveys of the 5% sample can be used to evaluate the condition of the entire secondary system.
