Abstract
ABSTRACT
The number of speed humps (sleeping policemen) in many countries has been
increased steadily in the last decades. In this paper, the problem of installing nonspecified
road humps in Cairo city has been studied. A simple measuring technique
has been constructed to measure hump profiles at different zones in Cairo.
Evaluation of the humps has been discussed based on the dynamic response of
crossing vehicles. This evaluation shows that road humps are randomly installed
depending on resident requirements which satisfy safety in their neighborhoods.
Many of these humps may cause vehicle damages and driver discomfort; therefore,
optimizing an ideal hump becomes one of the traffic control requirements. Optimized
hump dimensions for a new hump shape is introduced. The extreme acceleration of
the driver’s seats of a truck and a passenger car is set as a multi objective function
for the optimization process. The road-holding ability represented by the tire lift-off
speed has been taken into consideration. The optimal calculations are based on
Genetic Algorithm (GA) for its advanced searching ability. The results showed that,
optimized humps are favorable than the current local and standard humps for both
passenger cars and trucks.
