ABSTRACT The main factor that forms the perturbation, acting on the car in operating conditions, is the speed of movement. Analytical studies of operational properties and reliability indicators are based on the characteristics of traffic - distribution of runs and speed, in some cases obsolete, or incomplete and not correlated with the characteristics of the macro profile of traffic routes. The data on research of characteristics of the macro profile of country roads of the central Russia are given, their classification is offered. Stationary arrays of random values of relative mileages are allocated and the approximation of random speed distributions by analytic dependences is performed. The obtained results allow to simulate the car movement at early stages of design works and to improve the accuracy of the evaluation of parameters and characteristics studied. Keywords: car, perturbation, macro profile, analytical studies, theoretical methods, experiment, approximation, distribution, mileage, speed, projection, motion model.

As a result of the analysis, it is proved that the minimal element method allows to reduce the number of iterations several times. In solving complex problems of large dimension, the choice of a rational method plays a decisive role, which is demonstrated by the method of successively reducing this dimension by means of the algorithms used to optimize the distribution of shipments of goods.

The corresponding mathematical calculations are made. The results of the calculations showed that the application of the curvilinear profile increases the restoring force compared to the wheels having a conical surface. Simultaneously it was established that the restoring force plays the role of elastic force.

An important factor of the influence on transport and logistics aspects remains the discrepancy between the world practice of the regime and the procedures of operation of border checkpoints and customs, the absence of generally accepted tax and customs preferences abroad, including the creation of port special economic zones. It is shown that the basis for assessing the level of competitiveness in transport is the transition of the profitability point from the processes of physical transportation or cargot turnover to the area of transport and logistics services. Accordingly, various systems of criteria for the «attractiveness» of the seaport are applied. An integral row of such indicators-criteria for various conditions, goals and participants in the transport process is proposed. Among the prospects for development of seaports in the European part of Russia, the authors emphasize the option of combining all four modes of transport in the agglomeration of one port, which can dramatically increase its demand as an inter-regional transport hub. Keywords: economy, logistics, seaports, export, cargo transportation, intermodality, world market, competition, border checkpoints, customs.

The complex modernization of the transport frame of urban agglomerations in the construction of a high-speed highway can solve the transport problems that have accumulated over the centuries, positively affect the spatial and territorial development of cities, increase the efficiency of investments, and give a reasonably expected synergistic effect. Moreover, they may require even less money than planned at the construction stage (although this is not an end in itself), and the economic effect in the operation of high-speed railways, urban and suburban transport, promises to be higher than planned, and this opens up new prospects for the spatial and territorial development of towns and agglomerations located near HSR. Keywords: HSR-2, megacities, agglomerations, international transport corridors, transport and logistics systems, mutual influence, tracing, long-term effect. Editorial note: the article presents author’s opinion and is published as a discussion paper.

Therefore, as a replacement, it is offered to fulfill the delivery deadlines. At the same time, in conditions of the privatized car fleet, a combination of criteria for meeting the deadline for the delivery of goods and minimizing the processing of car flows at technical stations was required. In the process of calculating the plan for the formation of one-group trains, all streams of car flows, from the furthest ones, are consistently considered. If the accepted conditions are not met, the procedure of combining distant ones with shorter streams with their processing at one, two, three, etc. stations is performed - until the proper level of organization is achieved. Keywords: railway, train formation plan, design norms, combinatorics, terms of cargo delivery, organization of car flows.

It is shown that, for the most part, the causes of road accidents are violation of traffic rules by drivers and pedestrians, unsatisfactory road conditions. It was revealed that the greatest number of accidents occurs in the summer-autumn period. Most often, vehicle collisions and pedestrian collisions are recorded. About 40 % of road accidents with victims are committed in the foci of accident rate, the distribution of which directly depends on density of settlement of the territory and the functional specifics of the city’s administrative units. Keywords: motor transport, road traffic accident, accident rate on roads, foci of accident, severity of accident consequences, road safety.

Results of an assessment of ways to increase the efficiency of vibroprotective properties of blocks LVT-M are given. Proposals are made to improve the methodology for such an assessment, which should take into greater account the deformation characteristics of the track, the structural features of the tunnel and other structures in the metro zone. Particular emphasis is placed on the importance of using materials which dynamic stiffness is slightly higher than the static in the range of the studied frequencies of 2-63 Hz.

But professor Kurbatsky began his work as an ordinary fireman at a locomotive furnace. Today, very few people know about the intricacies of this profession, without which no railway train, headed by a locomotive, could do. The work of a fireman required very good physical training and skill. In addition to the constant casting of coal into the furnace, the fireman had to take a staff at each station. This procedure ensured the presence of only one train at a station. Sometimes this was done at full speed. At all stops at any time of the day a fireman was obliged to lubricate axle boxes with fuel oil, to fill a locomotive with water. About this first and distant stage of his railway life, the current doctor of science recalls with particular warmth, as it should be for a hereditary transport worker. Keywords: history, railway, steam locomotive, staff, axle box, fireman, memories.
