Aspects of modeling and simulation of the traffic management quality sustainable in an urban intersection

This paper presents a solution on the optimization of traffic lights cycle depending on the timeframe by developing a mathematical model. Based on the analysis and processing of data obtained from a traffic lights intersection with intense traffic in Sibiu, was developed a mathematical model that allows an algorithmic approach to programming sequences for ensuring a smooth traffic. The article also includes a section in which we synthesized examples of useful software in the analysis of urban traffic. The optimizing of the traffic light cycle in urban intersections, depending on the timeframe and implicitly, on the traffic volume, we consider that will increase the quality of traffic management, leading to a sustainable traffic, leading to time gain for those involved in the traffic of such intersections and also to a more efficient management of noise and gas emissions pollution from these intersections. Key-Words: Mathematical model, monitoring, quality of urban traffic, simulation, sustainable
