A RATIONAL APPROACH TO THE PROBLEM OF THE CHOICE OF THE SAFETY ROAD BARRIERS, THROUGH VALUATION OF THE TOTAL COSTS ON REMARKS OF STATISTIC AND PROBABILISTIC TYPE. PROCEEDINGS OF STRATEGIC HIGHWAY RESEARCH PROGRAM AND TRAFFIC SAFETY ON TWO CONTINENTS, GOTHENBURG, SWEDEN, 27-29 SEPTEMBER, 1989

A rational solution to the problem of the choice of the safety road barriers is possible through valuation of the total costs on remarks of statistic and probabilistic type. In fact, if the characteristics of the cross section and of the barrier (geometry, material, position, etc.) are defined, C will be the function of the independent variable TGM (average daily traffic for every carriageway) and p (percentage of heavy vehicles). Therefore, for confronting two types of barriers in a determinate road and for a determinate position (side or median), it will be possible to define, in a Cartesian plan that has in abscissa TGM and in ordinate p, a curve (locus of the points of same cost) that is border between two plane fields in the one which is most convenient to utilize one barrier rather than another. The process has been completely automathized, working out an opposite software for personal computer, so that, if same parameters change, it is immediate to re-calculate the cost function and to plot the curve of confront.
