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:
New Diesel exhaust gas aftertreatment systems, with DPF*) and deNOx (mostly SCR) inline application are very important step towards zero emission Diesel fleet. Solid quality standards of those quite complex systems are urgently necessary to enable decisions by several authorities. The Swiss Federal Office of the Environment BAFU and the Swiss Federal Roads Office ASTRA decided to support further activities of VERT to develop appropriate testing procedures and to define the quality criteria. The present report informs about the international network project VERT *) dePN (de-activation, de-contamination, disposal of particles & NOx), which was started in Nov. 2006 with the objective to introduce the SCR-, or (DPF+SCR)-systems in the VERT verification procedure. Examples of results with some investigated systems are given. The most important statements are: - the investigated combined aftertreatment systems (DPF+SCR) for dynamic engine application efficiently reduce the target emissions with deNOx-efficiency up to 92% (if operated in the right temperature window) and filtration efficiency based on particle count up to 100%, - the average NOx conversion rate at transient operation (ETC) depends strongly on the exhaust gas temperature profile and the resulting urea dosing control, - the NP filtration efficiency, which is verified at stationary engine operation is perfectly valid also at the transient operation. The present results will be confirmed in the further project activities with other systems and with different testing cycles. A special attention will be paid to the operational profiles, which are representative for low emissions zones LEZ.
