Evaluation Linear Method for Economic Prioritization of Traffic Tools in Rural Highway

Allocating budget to enhance highways safety is one of most important factors for reducing the amount of traffic crashes in several countries. Since the financial always isnt enough, reaching equilibrium between existing budget and problem is essential. Since traffic tools are the most important factors in reducing traffic crashes, in this research a model is presented for determining the best safety traffic tools which has profound influential on traffic accident. In this research firstly cost of different kind of crash like fetal, injury, and property damage only accident evaluated. For this purpose several factors such as cost of curing injured people or cost which is impacted from dying or disability of people to the society are considered. Beside that for choosing the best safety improvement method for variety rural highway section linear programming implemented in cost-benefit analysis. This method is one of the efficient, one criterion decision method in increasing beneficial in economic project. In this model besides considering cost of accident as fundamental factor of decision, the restriction of budget and problem in different section of the road are considered. One of the most characterizations of this model is considering more than one safety activity simultaneously. Finally, as a case study and for the sake of research validation, 91 km of Urmia-Salmas road, in west Azerbaijan province, was modeled. The outcome of this case study was proved to be satisfactory in terms of a set of best safety tools measures. The result is indicated that using some of economic safety improvement activity such as utilizing rumble strip or utilizing and improving horizontal and vertical signs have great influence on reducing traffic crash in variety sections of road. However, if suggested safety improvement activities are expensive for some of the sections, it is possible none of suggested idea accept for this section because of budget restriction.
