TI - Determination of tram’s actual speed based on the values verified by the ATM recorder
AB - The aim of the article is to present the differences between the tram speeds recorded in the recorder and those measured with a measuring device, and to propose the use of a correlation coefficient to determine the real speed. During the experiment, performed for an expert witness opinion, differences were found between the speed values recorded in the ATM recorder and those measured with the VBOX Sport device. It was also noticed that four speeds of different values had already been recorded in the recorder. The sources of these speeds are presented and the correlation coefficient between the measured and recorded values, which was used to reproduce the actual speeds and accelerations recorded during the real event, is calculated.
