TY - JOUR TI - Speed tests with the use of a motion assistive device AU - Ambroszko, Wojciech TI - Speed tests with the use of a motion assistive device AB - The article presents the results of research on the parameters of the movement of a person moving on various types of roller skates. An analysis and evaluation of the impact of the roller skate design on the achieved traffic parameters, speeds in particular, in terms of the possibility of reconstructing road events with the participation of roller skaters and conducting time-distance analyses was carried out. The tests were carried out in various road conditions, i.e. on the maneuvering yard and over long distances. The VBOX Sport measuring device was used for the tests. Using the V-Sim version 5.0, a simulation of a fall while roller skating was carried out, indicating the values of acceleration and velocity at the moment of hitting the head on the ground. The speed results obtained in various traffic conditions can be used in time-distance analyses, and the presented material indicates the complexity of the issue a as well as the need for an indepth analysis of a possible case.
