Effects of speed hump on vehicle performance in the Sekondi-Takoradi Metropolis, Ghana
Cogent Engineering, 2022 Upsurge in pedestrian-involved crashes, in the Sekondi-Takoradi Metropolis, has led to the installation of speed humps to ameliorate the situation. This has, however, attracted public complaints citing ride discomfort, vehicle damage and safety concerns.

Critical Analysis of Speed Hump and Speed Bump and Geometric Design of Curved Speed Hump
Transportation Research Procedia, 2020 Abstract The motive of this study is to critically analyze speed humps and bumps on various accounts such as travel time delays, mileage reductions, exhaust emissions and propose a new traffic calming device, which can retain the positive impacts of speed humps and also reduce the disadvantages associated with them.

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.
