This work 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 behaviour, the development of a driver behaviour model and the traffic light control. In order to conciliate all these requirements several lines of action have been taken simultaneously, such as the simplified and ordered representation of the lanes that make up streets and traffic islands, keeping interactions between drivers to the minimum, reducing the physical model of a vehicle to what is necessary for realistic driving and splitting the urban environment into zones. Additionally, several methods have been contemplated to produce traffic incidents, obstacles and obstructions that provide urban traffic with greater realism. The model thus obtained has its immediate application in training simulators, such as one that is being developed at the moment to train bus drivers in Madrid, and is also applicable to studies of traffic control by means of traffic lights, or studies of the impact caused by planning changes to city roads.
