Abstract:
THE PLANNING OF FOREST TRANSPORTATION SYSTEMS IS COORDINATED WITH LAND USE AND LONG-TERM RESOURCE MANAGEMENT INCLUDING THE PROTECTION FACTORS. THIS PLANNING REQUIRES A DETAILED INVENTORY OF THE TIMBER, MINERALS, RECREATION SITES, GRAZING LAND, FISH AND GAME, WATER AND HYDRO POWER, EXISTING ROADS AND TRIALS, AGRICULTURE, POPULATION, AND THE LIKE. THESE ARE ALL LOCATED ON MAPS AND THEIR VALUES, ANNUAL PRODUCTION, AND SUCH RELATED DATA ARE TABULATED. DECISIONS ON LAND USE ARE MADE ON THE PRINCIPLE OF MULTIPLE RESOURCE UTILIZATION. POPULATION CHANGE AND OTHER TRENDS ARE STUDIED AND ALL THESE DATA ARE CONVERTED INTO TERMS OF TRAFFIC, NOT ONLY FOR THE PRESENT BUT FOR THE FUTURE. FOREST TRANSPORTATION SYSTEMS ARE THAN PLANNED WITH STANDARD AND LOCATION OF EACH ROAD DETERMINED BY THE CHARACTER, VOLUME, ORIGIN, AND DESTINATION OF THE TRAFFIC. THE PLANNING INCLUDES AN ECONOMIC ANALYSIS OF EACH PROJECT. RESOURCE TRAFFIC HAS A VALUE DEPENDING ON THE PRODUCTS HAULED. TRAVEL FOR RECREATION OR THROUGH TRAFFIC ACROSS THE FORESTS HAS VALUES MEASURED BY COST OF VEHICLE OPERATION. THE YEARLY EXPENSE FOR THE ROAD WHICH IS THE DEPRECIATION AND INTEREST ON ORIGINAL COST PLUS ANNUAL MAINTENANCE IS REVIEWED. THE FACT THAT VEHICLE OPERATION, REPAIR, AND DEPRECIATION COSTS ARE GREATER ON LOW-STANDARD ROADS THAN ON HIGH-STANDARD ROADS FORMS THE BASIS FOR DETERMINING SAVINGS TO TRAFFIC WHEN IMPROVEMENT OF AN EXISTING ROAD IS PLANNED. /AUTHOR/
