Abstract
The article is concerned with comparison of the three transportation experiments using the two vehicle types (Tatra 810 and Tatra 815 MK IV) on two road types (higher and lower quality). From the transportation experiments, three datasets were obtained to be compared mutually and to the normatively determined values of acceleration coefficients, as well. In the article, the calculation of the probability of excess and double excess of the normatively determined limits is also included. For the purpose of the comparison, statistical tests of equality and three different parameters are employed. Statistically significant differences between the datasets are the outcome of the article, i.e. there are statistically significant differences between the vehicles and roads tested with regard to generated shocks. The results are primarily usable in the cargo securing system optimisation in road transportation and transport safety.
Highlights
Since 2013, the amount of cargo transported via roads within the European Union (EU) has been slowly growing
It follows from the European Commission estimation that in 2018 inappropriate cargo securing resulted in 2,886 truck road accidents, which makes for 13.2 % of the total number of road accidents in the Czech Republic
For the sake of comparison, a highly discussed problem - drink driving - was the cause of 4,626 accidents in 2018, which makes for 21.1 % out of the total number of road accidents, and drugs were detected in 260 road accidents, which makes for “only” 1.2 % [4]
Summary
Since 2013, the amount of cargo transported via roads within the European Union (EU) has been slowly growing. According to European Commission Directorate-General for Energy and Transport (currently European Commission Diractorate-General - Mobility and Transport) estimations, as much as 25 % of truck road accidents are caused by inappropriate or insufficient cargo securing [3]. Should the estimation (25 %) be applied to the Czech Republic in 2018, out of the total of 21,889 road accidents, 52.7 % are caused by truck drivers (11,542 accidents) [4,5]. It follows from the European Commission estimation that in 2018 inappropriate cargo securing resulted in 2,886 truck road accidents, which makes for 13.2 % of the total number of road accidents in the Czech Republic. For the sake of comparison, a highly discussed problem - drink driving - was the cause of 4,626 accidents in 2018, which makes for 21.1 % out of the total number of road accidents, and drugs were detected in 260 road accidents, which makes for “only” 1.2 % [4]
