FONSECA GUILARTE, Orlando; PUJOL FARINA, Gabriel Santiago; ALLENDE ALONSO, Sira  y  BOUZA ALLENDE, Gemayqzel. A tool to simulate and analyze traffic flow in an intersection controlled by traffic lights with variable cycle times. Rev cuba cienc informat [online]. 2014, vol.8, suppl.1, pp. 29-40.

The goal of this paper is to present a tool that helps establishing a good change policy for the time of the traffic lights at peak hours, based on the given experimental results. The intersection is considered to be regulated by traffic lights, and be composed by n streets and have k different light phases. The proposed simulator’s input consists of the characteristics of the intersection, and its output, the amount of cars that stay, arrive and exit it in each phase. It’s assumed that the arrivals and departures of vehicles follow a Poisson distribution whose parameter can vary within the studied interval. The simulation is based on discrete events, and to implement the simulator the .NET framework and C# language were used. This tool also allows obtaining statistical results that help the user to identify problematic hours and hence, to take decisions to determine the best option to minimize the traffic congestion.

Palabras clave : Optimization; simulation based on discrete events; traffic control; traffic lights control.
