Evaluación del impacto debido a la reducción del ciclo del semáforo en automóviles para mejorar el transporte no vehicular: Un caso de estudio en Lima

Faced with the new trend of sustainable and economical transport, the city is forced to develop infrastructure and transit technologies to incorporate pedestrians and users with non-motorized vehicles in the urban transport system. This research seeks to evaluate the consequences of optimizing a traffic light cycle with more equitable green times, which improves the movements of pedestrians and non-motorized vehicles (bicycles, scooters, skates, among others), without affecting the traffic of motorized vehicles (cars, buses, trucks and motorcycles). Field data such as speed of motorized and non-motorized vehicles per access, turns and movements per access, volume of motorized and non-motorized vehicles at the intersection, geometric measurements of the intersection; and the current semaphore cycle were taken into account to create a microsimulation in Vissim 9.0 software. This model was calibrated and validated through statistical evaluation, to represent a behavior similar to reality and simulate the current scenario. On the other hand, the field data previously collected was processed in Synchro 8.0 software, to obtain a new optimized traffic light cycle. With the new traffic light cycle obtained, Vissim 9.0 is entered for the microsimulation of the proposed scenario. Finally, 2 microsimulations are obtained, one of the current scenario and the other of the proposed scenario, which were compared using 3 variables to determine the impact of the implementation of a traffic light with more equitable green times. The variables compared were: the length of the queue by access, vehicles stopped by access and delay of vehicles by access. The results reflect an 11% reduction in the delay in vehicle access, an average decrease of 12.5% for the length of the queue, and an average reduction of 5% for vehicles stopped for access.
