Safety is one of the key aspects of the successful transport of cargo. In the case of road transport, the dynamics of a vehicle during normal events such as braking, steering, and evasive maneuver are variable in different places in the vehicle. Several manufacturers provide different dataloggers with acceleration sensors, but the results are not comparable due to different sensor parameters, measurement ranges, sampling frequencies, data filtration, and evaluation of different periods of acceleration. The position of the sensor in the loading area is also important. The accelerations are not the same at all points in the vehicle. The article deals with the measurement of these dynamic events with MEMS sensors on selected points of a vehicle loaded with cargo and with changes in dynamics after certain events that could occur during regular road transport of cargo to analyze the possibilities for monitoring accelerations and the related forces acting on the cargo during transport. The article uses evaluation times of 80, 300, and 1000 ms for accelerations. With the measured values, it is possible to determine the places with a higher risk of cargo damage and not only to adjust the packaging and securing of the cargo, but also to modify the transport routes. Concerning the purposes of securing the cargo in relation to EN 12195-1 and the minimum values of forces for securing the cargo, we focused primarily on the places where the acceleration of 0.5 g was exceeded when analyzing the monitored route. There were 32 of these points in total, all of which were measured by a sensor located at the rear of the semi-trailer. In 31 cases, the limit of 0.5 g was exceeded for an 80-ms evaluation time, and in one case, the value of 0.51 g was reached in the transverse direction for a 300-ms evaluation time.

The correct information, including the full braking deceleration of a vehicle, is an essential factor of the road accident process analysis. The aim of the paper was to define and compare the braking properties of the tested Tesla model S electric vehicle by means of the XL MeterTM Pro decelograph and a smartphone as a new alternative method. The measured procedure was the intensive vehicle braking by means of a fully pressed-down operation brake from the different initial velocities. Altogether, 32 measurements were carried out, out of which 16 on the dry surface and 16 on the wet surface. This paper contains the methodology and the results of the performed measurements. The data obtained by an XL Meter TM Pro measuring device were processed by means of the XL Visionä and PC Crash 11.0. software, whereas the data from the smartphone was analysed using the Diagram software. The results and data processed herewith can be useful for the forensic practice.

“…Dynamic events described in this article were addressed in the past and many outputs are published, like simulation model of the dynamic behavior of refrigerated products in a ship's refrigerated container by Bupič M. et al [12] or in applications of gyroscopic eff ect in transportation by Náhlík et al [13]. The studies of vehicle dynamics lead to the safety of transport as described in Vlkovsky et al articles [14], [27], [23] or in Skrucany et al [17], [25], [28]. The aerodynamics, crosswind, safety systems, braking systems, cargo distribution must be taken into account as it is in articles by Gnap et al [15], [21], Vrabel J. et al [18], as well as Rybicka I. et al [19] or Ondrus et al [20] [24] [29].…”

To ensure safety during transport within the intermodal chain, it is important to identify possible dynamic events that could affect the cargo. In the case of bulk cargo in an ACTS (Abroll-Container-Transport-System) container, the dynamics of the cargo and the vehicle vary during normal events such as braking, steering, evasive maneuver and the like. In this research, we used MEMS (Micro-Electro-Mechanical Systems) sensors to identify the parameters of acceleration at various points of container and to evaluate its impact on the cargo and vehicle. During the research, we also found out how the load of individual axles of the vehicle changed after performing normal dynamic events. One of the objectives was also to find out how parameters such as braking distance, braking time and mean fully developed deceleration (MFDD) change in the case of and empty and loaded ACTS container, as well as correlation analysis of values gathered from sensors placed on different parts of the container. The acquired knowledge can be used in the distribution and securing the cargo.
