In order to make road traffic safer and diminish the number of accident injuries and fatalities, there is a growing expectation that road accidents should be explored as thoroughly as possible. To measure the success of such explorations, this paper applies the concept of “assessability” of accidents, which shows how well an accident process can be...

Unmanned Aerial Vehicles (UAVs) offer a promising solution for road accident scene documentation. This study seeks to investigate the occurrence of systematic deformations, such as bowling and doming, in the 3D point cloud and orthomosaic generated from images captured by UAVs along an horizontal road segment, while exploring how adjustments in fli...

Background The classic accident reconstruction process is based on information recorded manually at the scene and gathered from witness statements. Liability cannot always be determined if no objective data are available, especially for accidents at traffic lights. Even Event Data Recorder (EDR) data (speed, braking, gas/brake pedal operation, etc....

The application of Event Data Recorder (EDR) in passenger cars and vans has been compulsory in the USA since 2014. In the European Union, every passenger car and vehicle manufactured and released must have e-call systems since April 2018. However, neither the data recorded in Event Data Recorders regulated by the current standards nor the data reco...

The assurance of process safety plays an important role in the field of information technology. Securing the information has become one of the biggest challenges in the present day. Whenever we think about the protected systems the first thing that comes to our mind can be malicious interventions which are increasing immensely day by day. Nowadays...

Cybersecurity is becoming more and more relevant. Autonomous vehicles handle large amounts of data and can connect to more and more existing devices, smartphones, tablets, or even other cars and systems. This poses the risk of unauthorized access to data. Theoretically cars have separate computer units, operate in isolation, and are not connected,...

Today, with the spread of autonomous functions in vehicles, the role accountability for causing accidents is emphasized. Self-guided functions work in certain traffic situations, but accidents happen, and, therefore, the following article presents an analysis of the issue. Its purpose is to show that vehicles with self-drive functionality do not pr...

Nowadays, the reconstruction of traffic accidents utilizing current vehicle technology presents new challenges for professional accident analysis. The downloading and reading of data stored in vehicles and the professional interpretation of these data is becoming important for full interpretation of the accident reconstruction. But this data cannot...

Nowadays, due to the constant change in the society's expectations regarding transportation, the main area of automotive development is the implementation of autonomous vehicle control functions. While with the gradual introducing and spreading of autonomous functions-even based on the previous experience-the decrease of the number of traffic accid...

Because of the significant maintenance and restore costs of the road, it is necessary to evaluate the road-friendliness of the suspensions. One of the damaging effects is the static load of the axles, which can be easily estimated. The other effect is the dynamic axle load, which can be calculated using more complicated procedures.

It can be difficult problem in the vehicle modelling the description of the systems that are inherently non-linear. There are some conventional modelling techniques, where non-linearities are approximated by mathematical formulas, look-up tables, numerical techniques or finite element approximation, where the system is replaced by limited quantitie...
