Some crossings and entroncamentos of the cities and roads are historically dangerous, in virtue of the occurrence of frequent collisions, some with registers of deaths. Then, why not to identify them and to promote alterations in the surface of the floors, the direction to improve the conditions of lockwire in these places? Thus, more adequate situations to prevent beaten lateral and to losses of lives would be created human beings. Over all some crossings with raised flow of vehicles and repetition of accidents could receive changes, to serve of archetype and evaluation, with the alert installation of systems of to the drivers and rise of the attrition tire-floor. How many people already had lost the life in crossings? Exactly when she has accidents without deaths, she has decurrent costs of the recovery of the involved ones and that they are assumed by the public power. Plus a reason of if thinking about implanting these alterations. This type of solution is applied in some countries as Canada, United States and in the Europe. The value of the investment is minimum and the enormous advantage, therefore it involves an alternative capable to prevent deaths of people or sequelas for the remaining portion of the life. The first step would be to identify the entroncamentos crossings and, that they would need to receive this type of intervention. After the application of the solutions, to monitor the occurrences of accidents to evaluate the effectiveness of the results. As everything starts for the vision and passes for decision politics, it expects that some representative of the society has interest in initiating a quarrel process on the subject.
