Urban traffic model for simulators

This paper describes the development of a traffic model for simulators of vehicles, pedestrians, traffic signs, and traffic lights within an urban environment. The model must optimize its capacities between difficult and opposing requirements such as the mandatory nature to produce results in real time, the high number of vehicles and pedestrians that must be simultaneously simulated, the most realistic reproduction of the vehicle's physical behavior, development of a driver behavior model, and traffic light control. In order to conciliate all these requirements, several lines of action have been concurrently taken. Additionally, several methods have been contemplated to produce traffic incidents, obstacles, and obstructions that provide urban traffic with greater realism. Thus, the obtained model has its immediate application in training simulators, such as one being developed currently to train bus drivers in Madrid.
