The purpose of this paper was to present a reliability comparison of two types of city transport buses. Case study on the example of the well-known brands of city buses: Solaris Urbino 12 and Mercedes-Benz 628 Conecto L used at Municipal Transport Company in Lublin was presented in details. A reliability index for the most failure parts and complex systems for the period of time failures was determined. The analysis covered damages of the following systems: engine, electrical system, pneumatic system, brake system, driving system, central heating and air-conditioning and doors. Reliability was analyzed based on Weibull model. It has been demonstrated, that during the operation significant reliability differences occur between the buses produced nowadays.
In freight road transport, the price per unit of transport is not the same for each shipment for reason, that many factors influence the cost of shipping. An important aspect, in addition to cost inputs, which decides, how high will the shipping cost it is the destination where the transportation takes place. The purpose of this article is to identify the impact of the change of destination on carrier costs. Authors will not deal with specific costs related to the change of destination, which include, for example, charges for the use of the road network or travel compensation to the driver, but will only deal with the probability of vehicle back-up. If the carrier is unable to backhaul of the vehicle, the initial shipping costs increase significantly.
The working conditions of truck drivers and social legislation are both topical and political issues in the field of road freight transport. The contribution outlines problems which are linked to the observance of the ban on weekly rest in the vehicle. Based on the judgment, the Court of Justice of the European Union explicitly forbids drivers to take their regular weekly rest in the vehicle. The contribution identifies the impact of the ban on spending weekly rest in the vehicle on transport planning in the EU. The aim of the contribution is also to highlight the existing problems in international road freight transport sector in connection with insufficient number of truck parks with accommodation.
