Abstract

The dynamics of the car rolling from a hump yard at a railway station is studied in its various aspects. The authors have also touched upon this topic repeatedly (see, in particular, World of Transport and Transportation, 2015, Iss. 6). However, earlier reports lacked estimates of time of movement and speed of a car on the intermediate section of the hump yard under the influence of tail wind of low speed. The published article fills this gap, introduces the results of calculations, mathematical and graphical dependencies enabling to make certain generalizations and conclusions.

Abstract

The problem of rational use of locomotives is quite acute. Here it is necessary to find the best compromise. In case of excess of locomotives there are less delays of trains, but locomotive costs are higher. In case of insufficient number of locomotives the situation is reversed. A model for calculating the optimal modes of turnover of train locomotives serving train flow isтoffered. The model promotes the further development of the dynamic transport task. The parameters of trains movement and the use of locomotives are provided, work schedules for each of them are built. The impact of the number of locomotives on the train’s mobility is estimated.

Abstract

One of conditions for securing flight safety is a restriction on intensity of an air traffic flow within the sector of air traffic services, as well as of the flows in the section of the route, in the route crossing points, at the aerodrome. To assess the capacity and to identify periods of peak load during the study, statistical traffic intensity data values within 14 days were analyzed. Data collection was carried out at Vnukovo airport in August 2015. The information on the number of departing, arriving and delayed flights with hourly intervals was organized by a number of criteria, a summary table on intensity and regularity of air traffic was drawn up. Measures to «smooth the peaks», based on the total cumulative practice, were offered.

Abstract

As any development of transport systems is impossible without the development of an appropriate package of normative legal acts, study of the theory and practice of transport law application is undoubtedly of importance. The reviewer appreciates the attempt of the authors to develop a theoretical aspect of the transport law, while the text remains well understandable even for the students in legal studies. While the reviewer does not share some authors’ views, e.g. the suggestion to consider transport law as an independent branch of law, he supports the idea of the development of advanced research in transport law.
