The phenomenon of vehicle congestion “Bottleneck”, is a problem that exists in every city focus of trade. The continued increase in vehicle demand is an immediate factor in the emergence of this phenomenon, especially in connections between states. This phenomenon of vehicle congestion may be due to inefficient track design, poorly programmed traffic lights, tight bends and vehicle accidents. The most effective solution for placating this phenomenon is the opening of new parallel collecting or local routes, in order to redistribute the vehicular flow of a pathway affected by the Bottleneck phenomenon. In this research, it was taken as a case of studying an intersection formed by an arterial pathway and a collecting pathway. This crossing is already saturated and without the possibility of increasing lanes, so it was feasible to open a parallel local track through a geometric redesign modelled in Synchro 10.0 software, with the purpose of redistributing the vehicle flow of the congested manifold, without impairing the quality of the transfer of nearby users and intersections. Critical ratio results “v / c” lower than 0.85 were obtained, which is synonymous with admissible capacities according to the criteria of states of the HCM 2010.
