FOOTNOTES [167] See “The Motor Bus Field as a Market for Trucks,” _Automotive Industries_, September 29, 1921. [168] One method of estimating cost of automobile riding, for a machine costing originally $1000, which having a life of 30,000 miles is then worth for scrap $100, may be given thus: Original cost expressed in cents per mile (1000-100)100 ------------- 3.0 30,000 Cost of repairs, estimated, 0.5 Gasoline and oil 2.5 Tires 1.5 Garage } Interest } Taxes } 1.5 Insurance } License } --- 9.0 The cost is about 9 cents per car mile. If an average of two passengers ride that is 4¹⁄₂ cents per passenger mile. The above is merely an illustration and cannot be applied generally. [169] See Bulletin 770, U. S.

CHAPTER VIII PLANNING HIGHWAY SYSTEMS: SELECTION OF ROAD TYPES A road is a strip of land set apart or appropriated for travel, public or private. When a road has been dedicated to the public or has been used so long that the public has a legal right of easement therein, it becomes a highway.[173]
