The increase in traffic congestion at urban intersections, particularly in Lima, reflects the need for dynamic solutions in traffic management. This study proposes an adaptive traffic light system designed and simulated in VISSIM, using selective detectors strategically placed in the most congested lanes. The methodology included calibration and validation of models based on real data, development of adaptive algorithms in VisVAP, and simulation of scenarios. The results demonstrated an average 20% reduction in delays, a 42% decrease in queue length, and an improvement in the level of service, eliminating the lowest performance categories. This adaptive and efficient approach can be replicated in other cities to optimize urban mobility and reduce costs associated with congestion.

In this research project, the evaluation of the accessibility and mobility difficulties faced by people with disabilities when circulating around a vehicular intersection is addressed. To carry out this evaluation, the Vissim and SSAM programs were used. The assessment of conflicts is carried out through the analysis of heat maps obtained with SSAM. In the context of this article, an analysis is carried out of the number of conflicts between vehicles on a road segment that is part of a traffic signalized intersection, characterized by the constant presence of congestion. Along this stretch, a decrease in lanes, variability in lane widths and lack of uniformity are observed, generating a point of congestion that gives rise to various types of vehicular conflicts. To carry out this evaluation, the micro simulation software VISSIM 8.0 was used, which models the real situation of the interse...
