A speed table (also called a bus-friendly hump, flat top hump, or raised pedestrian crossing) is designed as a long speed hump with a flat section in the middle. Speed tables are generally long enough for the entire wheelbase of a passenger car to rest on top. [ 25 ]
A common misconception is that the 80 km/h used in the simulation must also be used when physically measuring roughness with an instrumented vehicle. IQL-1 systems measure the elevation profile, independent of speed, and IQL-3 systems typically have correlation equations for different speeds to relate the actual measurements to IRI.
β° = Breakover angle; C = Underside of chassis; W = Wheel; G = Ground; M = Midpoint of wheelbase Example of a vehicle at a significant breakover angle.. Breakover angle or rampover angle is the maximum possible supplementary angle (usually expressed in degrees) that a vehicle, with at least one forward wheel and one rear wheel, can drive over without the apex of that angle touching any point ...
The cause of the damage: If you hit the speed bump due to reckless driving or exceeding the speed limit, your insurance may deny your claim, even if you have comprehensive coverage.
Speed – flow diagrams are used to determine the speed at which the optimum flow occurs. There are currently two shapes of the speed-flow curve. The speed-flow curve also consists of two branches, the free flow and congested branches. The diagram is not a function, allowing the flow variable to exist at two different speeds.
The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering [1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

An Actibump is an automatic speed-bump on a road. It is a product developed by the Edeva AB group, a Swedish traffic systems manufacturing company. It is triggered when a speeding vehicle drives over an activated piece of the road, causing a change in the level of the road as a warning to the driver. [1]
