This report describes a study to assess ground-borne vibration levels generated by a wide range of vehicle types crossing different road humps and cushion designs. For each vehicle, drive-bys were performed at speeds between 15 and 45 km/h which represented the range of typical crossing speeds recorded on the public highway for the profile designs used in the study. Ground-borne vibration was detected at a reference distance beside each profile design and the maximum level recorded for each drive-by event. The data was used to predict likely maximum levels of ground-borne vibration alongside each hump and cushion design for a range of site conditions. From these predictions, minimum distances between profiles and buildings to avoid disturbance to the occupants have been recommended. When selecting traffic calming measures, Highway Authorities may find the results of this study useful to reduce the risk of residents being exposed to levels of vibration likely to cause disturbance. Minimum distances from each profile design are also given within which minor superficial damage to buildings could possibly occur although the risk of this is generally small.
The similarity algorithm calculates how much two contents in the system are similar to one another. So far, similarity is calculated based on similarity of the project type, area of interest and user type. Generally, if two contents have more parameters in common they are more similar to each another. More information.

While we are still building the FEHRLopedia with the help of experts like yourself, you may find that not all subjects are covered as deeply as you need. Therefore if you don't find the results you are looking for, please try the CERTAIN custom Google search. We would be grateful if you would create new content for the FEHRLopedia from your results. Thanks for your assistance in building the system.
