The integral factors of road traffic constitute the basis of the traffic system and are composed of the human element (Man), the mechanical element (the vehicle), and the physical or environmental element (the public road and its conditions). The constant interaction between these three elements determines traffic safety and fluidity. The remaining options are incorrect because they are incomplete. Focusing only on Man as a driver and pedestrian, or only on the vehicle and the driver, excludes fundamental elements such as the road infrastructure itself (the road), which plays a crucial role in road circulation and road safety.
