В третьей части статьи описывается новый алгоритм, основанный на методе энергетических окон. В алгоритме использован итерационный процесс, в котором оптимизируются значения величин сглаживания, пороги срабатывания по каждому окну и на каждом временном шаге при движении транспорта через зону контроля. В качестве входной информации используется ряд параметров монитора, которые непосредственно измеряются на месте инсталляции или производства монитора.

New algorithm is described in the third part of the paper. It uses method of energy windows and is based on iterative scheme. Values of smoothing and thresholds are optimized in each energy window and time step during of movement of transport through control zone. Some parameters of monitor which are measured on the place of its installation or manufacturing are used as input information.
