The results of the implementation of the proposed methodology are presented, on the example of the projected road network of one of the micro districts of the city of Omsk. Graphically presented are the results of measurements of changes in the daily traffic intensity of both directions on the projected section of the road network. The assumption about the influence of the period of continuous survey of traffic intensity on the occurrence of an error in the obtained numerical values was experimentally confirmed.
