In recent years has developed the concept of road safety; already it is not violence or road tragedy only on public roads, but also on the private public-use tracks, which are different concepts. The modern application of the modality of road concession has given reason to this reflection. As a result, and chained form, resulted in the arrival of a new tool called road safety auditing road or simply, security audits. The excessive growth of the vehicular field related to the number of inhabitants – rate social monitoring – without the planned development of appropriate road infrastructure or adequate investment to secure road construction programmes; as well as the lack of actions and measures in the short, medium and long term in the field of road safety within the framework of a good design and application of comprehensive Plan of road safety policies bring as a consequence an uncontrolled growth of indexes of accidents, also constituting new terms. On many occasions we have affirmed that road safety is inherent to the crises plaguing today humanity energy, petroleum, financial, environment, power, transit – since the fatalities and injuries by traffic not occur without vehicular circulation.
Motor vehicles moved mainly by fuels derived from petroleum, and these produce harmful gases to the environment; Today the traffic of cities are regulated by controls that work with electrical energy generated by thermoelectric plants containing petroleum, aside from being lit to preserve citizen safety and provide greater visibility to users. We have seen on the other hand, as the financial crisis in the world directly affects the prices of fuels and also the economies of non oil-producing Nations. We will not consider the costs by congestion on the road network, on this occasion. Nor we will consider the costs health by pollution to the environment by the transit, nor losses in electric power. But it is important to mention that there are work methodology that yield these results, but also the costs of the time saved by the users of waterways to implement efficient and effective measures in circulation.
