Technical culture as a stimulant for social costs of the use of public space

Niejednokrotnie osoby odpowiedzialne za przewóz towarów lekceważą limit nałożony na dopuszczalną masę całkowitą pojazdu, dążąc do maksymalizacji zysków. Należy jednak pamiętać o kosztach napraw pojazdów uszkodzonych na jezdniach zniszczonych przez przeciążone ciężarówki oraz, w szczególności, o ogromnych kosztach ponoszonych przez podatników w celu ochrony środowiska naturalnego. Kluczową kwestią staje się edukacja młodych osób.Often people responsible for the transport of products disregard the limit imposed on the permissible laden mass of the vehicle, seeking to maximize profits. However, they should be aware of the costs of repairing vehicles after using roads damaged by overloaded trucks and, in particular, of the huge costs incurred by taxpayers in order to protect the environment. It becomes crucial to educate young people

Selected problems of technical education with the use of computer simulation as an example of correlation between trucks weight and road infrastructure damage

W artykule zaprezentowano przykład komputerowego wspomagania dydaktyki w zakresie kształcenia kultury technicznej w ramach przedmiotu zajęć technicznych. Program zasadniczo adresowany jest do odbiorcy z klas IV–VI szkoły podstawowej, jakkolwiek jego przeznaczenie do wykorzystania w edukacji dorosłych uczestników ruchu drogowego jest oczywiste w realiach naszego kraju. Zaproponowany w materiale program komputerowy jest odpowiedzią na zidentyfikowany problem związany z przeciążaniem samochodów ciężarowych. Znaczenie społeczne poruszanego zagadnienia jest istotne z uwagi na powszechność występowania tego zjawiska oraz wysokie koszty społeczne związane z koniecznością restytucji infrastruktury drogowejIn the paper an example of computer assistance in teaching in the field of technical culture education as a part of the technical classes is presented. The program is addressed to classes IV–VI of the elementary school, however, it is obvious that in the realities of our country it is also necessary for educating adult traffic participants. Program proposed in this material is an answer to the identified problem connected with the overloaded lorries. The social importance of the touched subject is significant, due to the commonness of such phenomenon, as well as the high social costs associated with the necessity of the road infrastructure restitution

Influence of Trajectory and Dynamics of Vehicle Motion on Signal Patterns in the WIM System

This paper presents the analyses of the signals recorded by the main sensors of a WIM test station in the cases of abnormal runs (i.e., runs with the changes of trajectory or the dynamics of vehicle motion). The research involved strain gauges which are used for measuring the weight of vehicles, inductive loops, as well as piezoelectric sensors used, inter alia, to detect twin wheels and to determine where a vehicle passes through a station. Since the designers intend the station to be able to implement the direct enforcement function, the selection of runs deviating from the normative ones constitutes an important issue for the assessment of the measurement reliability. The study considered the location of the trajectory of the runs, the dynamics (acceleration/braking) and the trajectory changes. The change in the amplitude and the value of the signal recorded by the strain gauges as a function of the location (position) of the contact between sensor and tires is a noteworthy observation which indicates the need to monitor this parameter in automatic WIM systems. Other tests also demonstrated the influence of the analysed driving parameters on the recorded results. However, by equipping the WIM station with a set of duplicate strain gauges, the measurement errors of the gross weight and axle loads are normally within the accuracy limits of class A(5) stations. Only in the case of accelerating/decelerating, does the error in measuring the load of a single axle reach several per cent

Numerical analysis of factors, pace and intensity of the corona virus (COVID-19) epidemic in Poland

This article focuses on a statistical analysis of the corona virus disease 2019 (COVID-19) data that appeared until November 31, 2020 in Poland. The studied database, expressed in terms of both population and air pollution (particulate) indicators, is provided mainly by the Airly company, the Central Statistical Office (GUS) and the Rogalski project. The particular measured factors, which underwent standardization, were assessed for mutual dependency by means of a Pearson correlation coefficient and analysed by a linear regression. Based on the presented models, our results indicate that air quality (air pollution level) is the most important factor in the context of enabling COVID-19 case load increase in Poland
