Abstract:

THE SELECTION OF FEDERAL AID SECONDARY HIGHWAYS IN THE STATE OF WASHINGTON WAS BASED ON THE HYPOTHESES THAT THE PRIMARY AND SECONDARY ROUTES MUST FORM AN INTEGRAL SYSTEM BECAUSE THE PRIMARY AND SECONDARY HIGHWAYS ARE GENERALLY OVERLAPPING IN SERVICE CHARACTERISTICS; THAT THE PRIMARY SYSTEMS NOW DESIGNED ARE NOT BASED ON SPECIFIC SERVICE CHARACTERISTICS AND PERHAPS PARTS SHOULD BE SECONDARY; AND THAT AN INTEGRAL SYSTEM OF PRIMARY AND SECONDARY ROUTES MAY BE SELECTED LEAVING A TERTIARY SYSTEM WITH A RATHER DEFINITE POINT OF INDICATION AS TO THE BEGINNING OF THE TERTIARY SYSTEM. THE HYPOTHESES WERE SUBSTANTIATED BY MEASURING SERVICE TO DWELLINGS, SCHOOL BUS ROUTES AND POSTAL ROUTES, AND TOTAL TRAVEL IN EACH COUNTY AS WELL AS SERVICE TO PROPER LAND USE. THE GUIDES USED IN THIS SELECTION WERE "RURAL TAXABLE LAND" AND "RURAL POPULATION" FACTORS APPLIED TO COMBINED PRIMARY AND SECONDARY MILEAGE WITH THE PROVISION THAT EXCEPTIONS IN THE AMOUNT OF MILEAGE DETERMINED FOR EACH COUNTY MUST BE MADE FOR SPECIAL CONDITIONS. THIS STUDY SHOWS THAT IT WOULD BE ALMOST POSSIBLE TO ELIMINATE THE USE OF FACTORS FOR MILEAGE ALLOCATION TO EACH COUNTY AND USE A UNIFORM PERCENTAGE OF TRAVEL SERVED TO DETERMINE THE COMBINED MILEAGE OF PRIMARY AND SECONDARY ROUTES FOR EACH COUNTY. /AUTHOR/
