A large-scale study on the speed-calming effect of speed humps [PDF]
Transactions on Transport Sciences, 2020 Inappropriate speeding is one of the main causes for traffic-related injuries and fatalities. Studies have shown that more than 50 % of Danish car drivers regularly speed on urban roads and nearly 75 % of them speed on rural roads. Physical speed-calming measures, particularly speed humps, are widely used to reduce speeding in urban areas in the Danish

Traffic of multi-car trains in marshalling yards [PDF]
E3S Web of Conferences, 2023 Developing rail transport is one of the world's greatest challenges. Rail transport reduces emissions and is the most energy efficient means of transport. An important element of the railways is a hump yard, where rolling stock is formed.

Updating the numerical characteristics of main resistance to wagon movement when rolling down a hump [PDF]
E3S Web of Conferences, 2023 The parameters for humps are designed by the results of the roll-down of wagons with the design running performance. The numerical characteristics of the main specific resistance forces to the movement of wagons currently used in hump design are given in

Analysis of the movement of an empty car on the longitudinal profile of the hill [PDF]
E3S Web of Conferences, 2023 At present, in the existing methods for determining the height of a hump, the height is calculated based on the most difficult conditions - winter temperature and head wind, and a four-axle empty covered wagon is selected for a poor runner.
