Resumen
During the last decades, designs of two-wheel motor vehicles (TWMV) have been significantly improved, which is why it is required to bring the analytical tools used to estimate their braking parameters in line with those designs. However, the current expert analysis practice applied to motor vehicle accidents (MVAs) still uses for calculations the values of deceleration time and steady state deceleration for old, domestically manufactured motorcycles which are today rarely used for travel. Both these circumstances require processing, clarification and establishing an updated basis of TWMV deceleration estimate in order to enhance credibility of such estimate used in expert examination of MVAs, i.e. to ascertain the drivers? compliance or non-compliance with traffic regulations, to justify causes of accidents, to determine whether the driver could or could not have prevented a particular MVA.
