Analytical model to determine the quality factor used in transport network

Abstract

Road transport has become one of the most used types of transport currently, issue that has generated many problems as congestion, pollution and accidents. For these reasons, the related studies of the traffic optimization, have known a great development. Due to the complexity of traffic, most of the performed studies have used simulation models. In this paper, the authors propose a new analytical model to determine the quality factor used in transport network. The model takes into account both the street configuration: lanes, width of lanes and traffic light in system present or absent; and the dynamic component that specifies a particular existing traffic: number of vehicles, the length of time of crossing the intersection. The result of the modeling is a numerical value that describes the quality of streets. This factor is used to characterize the global traffic in the intersection and also to optimize traffic in a structure of the interconnected intersections. The use of this model of quality factor helps to unify the elements of road traffic system with classical theory of queuing network. The novelty of this model is to incorporate the main features present in static and dynamic traffic. It uses the classical theory of queuing networks applied in traffic modeling.
