На основе их проведена регистрация продольных и микропрофилей 5 типов дорог. Выполнен анализ их характеристик по параметрам перемещений, скорости, ускорениям в третьоктавных полосах частот. Предложено оценивать ровность дороги по скорости изменения уклонов в полосе 0,16–0,4 Гц: до 0,15 м/с – дороги с малыми уклонами, до 0,25 м/с – небольшими, до 0,3 м/с – средние, свыше 0,4 м/с – большими. Качество микропрофиля дорог целесообразно оценивать по спектру среднеквадратической скорости микропрофиля в третьоктавных полосах 6,3–12,6 Гц:  до 4 см/с – дороги отличного качества, до 6 см/с – дороги хорошего качества, до 8 см/с – дороги удовлетворительного хорошего качества, свыше 10 см/с – плохие.</p></abstract><trans-abstract xml:lang="en"><p>Are considered existing and new methods of gaugings of longitudinal and microprofile – of the big sites of roads in the course of the vehicle movement, based on gaugings of longitudinal discharge angles of the vehicle, speedups sprung and unsprung mass and their mathematical transformation in package MatLab/Simulink are offered. On the basis of them registration longitudinal and microprofile of 5 types of roads is spent. The analysis of their characteristics on parametres of conveyances, speeds, to speedups in 1.3 octave strips of frequencies is made. It is offered to estimate flatness of road on speed of change of biases in a strip of 0,16–0,4 Hz: to 0,15 sm/s – roads with small biases, to 0,25 sm/s – small, to 0,3 sm/s – averages, over 0,4 sm/s – big. Quality of a microprofile is expensive to estimate expediently on a spectrum squared magnitude speeds of a microprofile in 1/3 octave strips of 6,3–12,6 Hz:  to 4 sm/with – roads of excellent quality, to 6 sm/with – high quality roads, to 8 sm/with – roads of satisfactory high quality, over 10 sm/with – bad.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>автомобиль</kwd><kwd>продольный профиль</kwd><kwd>микропрофиль дороги</kwd><kwd>Raspberry</kwd><kwd>Matlab/Simulink</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the Vehicle</kwd><kwd>longitudinal profile microprofile of road</kwd><kwd>its reception by means of minicomputer Raspberry and transformations in Matlab/Simulink</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>нет</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Хачатуров, А.А.
