The cyclist’s visibility and the safety on the road remarkably can be improved by integrating not only the light reflective, but also light emissive elements in the cyclist’s suit. There’s drawn up the prototype of cyclist’s belt with integrated LED stopping signals, which light up constantly when cyclist is braking. The LEDs are activated by signal coming from the accelerometer, placed in the central back belt pocket. During of approbation it’s defined, that placement of sensor didn’t provide a proper activity of stop signals, due to high level of addition cyclist’s movements during the riding. The research of oscillation of the anthropometrical points on the body back was carried out to clarify the most appropriate placement of accelerometer to design the cycling jacket. The motion capture technology and cycling exercise equipment for cycling imitation were used. As a result the motion sensor must be placed in the middle of the back upper part of the designing cyclist’s jacket.
