Movement analysis of the semitrailer with the tank-container at hard braking -the case study

Abstract

Transport of liquid, gaseous, powdered or granulated substances is an integral part of the industry in each country. This type of cargo is most often transported by companies that are a part of petrochemical, food or also other types of industry. Increased attention should be paid to transport of tank-vehicles and tank-containers from the point of view of road safety and environmental protection. The volume of such types of transport is growing every year. The extensive trend relates mainly to the developed world economies, which are experiencing economic growth, which includes also Slovakia according to the Statistical Office of the Slovak Republic. This article deals with evaluating the movement of semi-trailer trucks with a tank container during and immediately after hard braking. The movement of the semi-trailer truck with a tank container will be analysed and evaluated immediately after the vehicle is stopped. The movement of the vehicle will be analysed by video analysis. The focus is on analysing behaviour of the semi-trailer truck with a tank container during and immediately after braking. The article compares semi-trailer trucks with tank container with breakwater plates and tank containers without breakwater plates. An important feature of this comparison was processing of videos capturing these vehicles during hard braking in video analysis program.
