Klimenko I. Improvement of a methodica of designing of reconstruction of horizontal curves autoroads in view of the fuel economy.

In the dissertation the decision of a scientific and technical problem of designing of reconstruction of horizontal curves roads is given which is directed on economy of fuel resources and reduction of pollution of an environment. The system approach is applied, the system " road conditions - transport a flow - environment " is investigated. With the help of methods of mathematical modeling with use of numerical experimental researches and simplex-method the dependence of the charge of fuel and pollution of an environment from parameters is established: variable radius of a curves, movement speed of the automobile, visibility in the plan, width passing of a part. The technique calculation of the charge of fuel by the automobile is developed at horizontal curves. The rational type of a curve with point of view circle of sight save energy for different conditions of movement is determined. The technique of definition of power resources economy is transferred in "Ukrgiprodor". Key words: system"road conditions - transport flow - environment", horizontal curves, mathematical modeling, simplex - method, radius of a curve, speed of movement, visibility, width of a road, fuel economy.
