Small portable device for measuring skid resistance of road surfaces over area of up to 0.2 sq m was developed; experimental specimen is about 5 kg in weight and 45 ×40 × 15 cm in size; measurement is effected by pressing pedal of interlocking device; single measurement, including preparatory operations, takes 30 to 50 sec; correlation dependence between values of friction determined by dynamometric trailer and device, and between number of traffic accidents and values of friction coefficients determined by device.
