After 2013 Cusco city presents an increase of the traffic accidents in the urban vial network, due to the increment of the automotive stock, deficiencies in the geometric design, deterioration, and lack of maintenance of the network. A tool for the vial security of necessary to address this problem by implementing it in the urban sector. This study focus in the analysis of the vial security of high risk intersections in Cusco city applying an alternative methodology which is a combination of conflict analysis and principal component analysis This thesis aims at establishing an alternative method which permit to quantify the accident rate of an intersections by obtaining a response variable, the risk index. The experimental development was made through field studies, by convenience urban intersections with T and cross (+) shape were selected for the characterization of the conflicts. The variables selected were the braking distance, velocity of acceleration, time to collision, time posterior to invasion and time of evasion. It was concluded that high values of the risk index represent a higher risk that a conflict becomes an accident, thus the role of the sign in each variable is relevant. Velocity of acceleration has a negative sign in the risk index formula, since higher is the velocity, higher the probability that exist a collision in the studies conflict. The risk index obtained is between 10.94 and 63.91, these represent medium risk of accident in the two instrumented intersections. In addition, it was determined that the risk of these two intersections is smaller than the risk of the other four intersections. This is due to the fact that non-instrumented shows a smaller volume of traffic that instrumented intersections. Finally, it should be said that the methodology presented in this study has not been employed previously in Peru. Then, further research should be implemented by authorities in urban areas.
