In Egypt, speed humps are often thought as the best and cheapest tool to reduce vehicles speed and consequently decrease the number of potential accidents.
The lack of standards in Egypt led to the installation of a number of speed humps with random dimensions and without good justification.
They have become in many cases a source of disturbance and discomfort to drivers and passengers especially when they are poorly designed and located.
So, standard design guidelines are disparately required.
Three streets from the urban road network of Kafr El-Sheikh city were chosen to collect field data.
A total of 51 speed humps were chosen for field data survey.
Although there are many design shapes of speed humps, the study focused only on the sinusoidal type.
As observed in the field survey, it was found that more than 74% of the observed road humps were of the sinusoidal type.
The screening process resulted in only 24 sinusoidal shape speed humps from the 51 speed humps firstly chosen.
For speed measurement, data were collected by installing a recording camera beside the road carriageway of each speed hump for an hour time interval.
Spot speed for three types of vehicles was measured from the recorded videos for each site by using the logger program software.
The operating speeds (V85%) at humps locations have been obtained for different vehicles.
Regression analysis models were developed to represent the relationships between the operating speeds (V85%) at humps locations for motorcycles, passenger cars vehicles, and microbuses and three variables, hump length, hump height, and the spacing between successive speed humps.
Generally, the results demonstrated that spot speed is significantly influenced by speed hump geometric dimension and the spacing between them.
Finally, the developed regression lines can be used easily for setting the geometric dimensions for each proposed hump location.
