Programmatically implemented in MATLAB algorithm for calculating the intensity of the transport stream for the acoustic emission of cars based on the fixation of the amplitude value of the acoustic signal. The software allows you to change the threshold for fixing the amplitude value. For the approbation of the proposed software, field studies were carried out on the street-road network in Penza. Practical implementation of the software may require the introduction of an adaptive threshold, depending on the number of lanes of the road.
