Undoubtedly, conflicts on intersection roads leading to accidents are very often observed. This is due to the ineffectiveness of fixed-cycle traffic lights that do not adapt to changing urban traffic situations. Based on this, the present research evaluated as a case study an intersection located at Habich Avenue with Tupac Amaru Avenue in Lima, Peru. The article also looks for alternative solutions based on the microscopic representation of the intersection using microsimulation programs such as VISSIM and SSAM. In addition, a codification of traffic light cycles was implemented to allow a continuous flow to the Bus Rapid Transit (BRT) system, indirectly reducing the number of conflict points in urban transport. Moreover, the relationship between the reduction of delays and conflicts was identified. The results indicate that a direct relationship between the evaluation parameters was found from the improvement in the traffic light phases. Delays on the east access decreased by 42% and on the west access by 31%. What is more, 12679 rear-end conflicts and 1727 lane change conflicts were reduced.
