【 摘 要 】

Based on the analysis of the experimental data the article reveals that if in the area under study a travel length is more than 7 km (about 20 minutes of movement), it becomes possible to obtain stable relationships between the specific parameters of traffic in the network. A further increase in the duration of observations does not cause a change in the trip parameters and the value of the correlation ratio for the model. The corresponding results are achieved with a constant cruising of five "floating" cars in the area under study. Moreover, it is proved that reliable results of estimating the traffic parameters on the network are obtained both for fixed traffic routes of "floating" cars and for randomly choosing routes.
