Abstract. Due to the growing level of motorization while maintaining the capacity of existing roads, as well as due to the need to design and build new ones, the question of assessing the quality and reliability of traffic management is becoming increasingly relevant. The development of engineering and technology of geographic information systems allows to optimize the collection and processing of data on the actual condition and functioning of road networks.
The aim of the work is to prepare a methodology for assessing the travel time and buffer indices based on data from navigation equipment.
The proposed methods are based on practical experience gained in collecting and processing information from navigation equipment in the form of tracks.
A two-stage approach was used to evaluate the travel time and buffer indices based on data coming from navigation equipment. At the first stage, you should select the estimated areas, determine their boundaries and coordinates, as well as the frequency of measurements. At the second stage, the selection, processing and, if possible, restoration of data that meets the criteria defined in the first stage takes place.
Analysis of the description of the operation of the «Yandex.Probki» service, using data from navigation equipment, showed a similar approach to the collection and processing of information and, as a result, the possibility of using the data provided by this service to evaluate time and buffer indices. As a result, a methodology was proposed for calculating the travel time and buffer indices based on the data of the «Yandex.Probki» service, which makes it possible to evaluate the quality of service within the framework of the road network or its part.
The proposed technique allows you to calculate the travel time and buffer index, as well as evaluate the quality of service based on data coming directly from road users, without using a car laboratory, thereby significantly reducing the complexity and cost of collecting and processing data.
Further work should be aimed at testing this methodology and determining weighting coefficients for assessing the quality of tinning within the framework of the road network or part thereof. In addition, the most important area of research should be the economic assessment of losses caused by congestion, based on the travel time and buffer index.
Keywords: travel time index, buffer index, level of service, traffic monitoring,street-road network.
