Abstract

It's presented here a Multicriterial Analysis for traffic accidents that has figured as one of the main modern society problems, especially in developing countries. This study aims to obtain the best alternative of investment to reduce the accident rate in Brazil, in a medium and long terms. The Analytic Hierarchy Process - AHP was used to obtain the best solution among the alternatives considered in the model: traffic education, fiscalization and enforcement, road maintenance and null alternative, taking in account the goals and interests in relation to the actors involved or affected by the problem. In order to apply the methodology the problem must be structured by a hierarchy that presents in each level the relevant elements in the traffic accidents analysis. Here, the hierarchy has four levels: objective, actors, interests and alternatives. These elements were previously identified and defined according to their influence in traffic accidents. The results of this methodology confirm its validity of the priority the alternatives to promote road safety. These results indicate that Government is the most influential group with relative priority of (0,27), followed by drivers (0,21), pedestrians (0,18), traffic police (0,14), regulations (0,12) and public owners (0,08). To each actor the results also indicate the most important objectives. To Government, the most relevant was cost with a priority of (0,40) and road improvement (0,31) was the best one to the drivers. To pedestrians and traffic police, segregation (0,39) and salary ( 0,39) were the most relevant objectives, respectively. To regulations, the specific curriculum was the most important objective with a priority of (0,64) and public owners, to eliminate illegal competition (0,67) was the best one. The final results indicate that to invest in traffic education is the best alternative to reduce accidents rates, with a priority of (0,44), followed by fiscalization and enforcement (0,27), road maintenance (0,22) and null alternative (0,07). Based on these results, traffic education guides were elaborated for elementary schools, presented in three parts for children and adolescents. In an appropriate language, these manuals include safety rules regulation having in minds how to aware children and adolescents to behave as councils users of the transportation system. They are based on the Brazilian Traffic Code that was effected since January 23 T h , 1998.
