Smirnova N. The methodology of the project solution target search for two-lane public roads

The dissertation is devoted to solving methodological problems of directional finding for public roads' design solution in the field of transport indicators of performance throughout the lifecycle. The actual problem of research provided is a theoretical and practical decision processes of cars interaction, constituting the traffic flows from road constructions in real road conditions through the vehicles theory patterns. For the first time movement patterns of traffic flow in real road conditions, defined by technical parameters of the road and its operational status allowing one to describe any mode of movement of traffic flow for typical traffic conditions on the roads were studied. Regularities of probability distribution of intervals between vehicles in the flow were substantiated and confirmed experimentally. Thereby creation of improved model of shifted exponential distribution of intervals allowed to assess the ability to perform overtaking in traffic flows on different road conditions.The research results allowed to develop innovative methods for roads quality assessment compliance on all possible speed of 85-percent of availability, based on traffic flows modeling with the help of theory of operations research with the calculation of probability characteristics of the vehicles in the flow. For the first time algorithms of highway functioning study to meet the need for safe and economic transportation for its life from the time of construction to reconstruction through a series of current and capital repairs were developed. That allowed the development an appropriate software. Keywords: traffic, road operation simulation, life cycle, speed, transport and operation characteristics, technical level parameters.
