Opis:
The paper discusses the need of additional equipment of trucks which are already being in use in Poland with the devices of the indirect visibility which enable to observe much bigger area in the neighbourhood of the vehicle. A large number of accidents are caused by drivers of larger vehicles who are not aware that other road users are very close to or beside their own vehicle. These accidents are often related to a change of direction at crossings, junctions or roundabouts, when drivers fail to detect other road users in the blind spots, which exist in the immediate area around their vehicles. The increase of the indirect visibility from the driver's seat improves safety of the participants in the road traffic. Over 400 people lost their life in the EU in of these accidents. Most of the victims of such accidents are pedestrians or two-wheelers, a particularly vulnerable category of road users. Implementation of the EU Directive 2003/97 (which is obligatory for the new vehicles) to the vehicles earlier registered can be done by replacement and installment of the new mirrors which contain bigger areas. This paper shows the results of the research on the independence of minimum dimensions (s, w) of mirrors class V and its placement on values of radius of curvature. It contains much bigger area than it is due to demands. Author also made a proposition on how to solve the problem of the limited visibility on the inclined crossing of roads and on enlarged crossing while turning left.

Opis:
Night-time visibility is essential for road traffic safety. It depends mostly on quantity of light falling on the objects important to be seen to avoid collision. The relatively simple and easily understood criterion for quality of passing beam is visibility distance. In fact visibility distance of driver using headlamps is a much more complicated function of many factors such as design of headlamp, light source used, mounting height, aiming, change of beam pattern inclination during change of vehicle load. From point of view of legal requirements it is important to meet all requirements concerning all mentioned factors. But the problem is that there are separate legal requirements for light sources, headlighting systems and mounting conditions on vehicle. Final visibility distance is significantly influenced by coincidence of all this performances but also by visual possibilities of driver and road conditions. The process of requirements creation is complicated. A number of experts work on them for a long time. It is influenced by technical progress, market needs, level of knowledge and experience. . In this paper author describes influence of important factors for present state of possible and real visibility distances in dependence on technical design, kind of light source used and way of creation of type approval requirements and propose improved concept for aiming and levelling.

Opis:
In the report there is discussed the problem of changing demands in the binding rules concerning the technical conditions. During maintenance, the lack of information from the surrounding of the vehicle is one of the reasons of collisions and accidents. There is a radical limitation of unobstructed observation of the whole area surrounding trucks of N1 category in comparison to the car of M1 category. Vehicles which have the same body and which are designed to transport people - M1 category or load – N1 category, they have different equipment, such as side glazing and back walls. Those who are driving these vehicles do not have comparable and identical visibility. The open loadcarrying body in the truck creates the screen obscuring of the big part of the vehicle's surrounding which precludes the direct observation of the considerable area. The devices of the indirect visibility enable to observe only the part of the area, which is directly invisible. There is an important need to change the regulation as far as construction and vehicles equipment is concerned. This paper offers the change of the philosophy of the regulations requirements in the area of visibility. Technical progress and development in the area of visual transfer devices helps to use them in the vehicles in order to improve the possibility of observing the surrounding of the vehicle. There is no reason to tolerate the worse visual transfer in the vehicles N1 category.
