Special aspects of the use of 'floating' cars information to estimate the quality of road traffic in real time

摘要

The article provides a rationale for the transition from the existing estimation methods of traffic conditions, focused on a single car-laboratory, to total "floating" cars methods of estimation at the network level. The paper presents the results of cluster and dispersion analyzes of experimental data. Based on these results it was concluded that a reliable estimation of the proportion of simultaneously stopped cars can be carried out when measuring traffic parameters with different time discreteness in the range from 1 to 180 seconds.
