Computational Design Optimization Of Road Speed Bumps

In this study, for urban traffic control; several speed bump forms are proposed as novel designs by the usage of design optimization algorithm. A generic automobile suspension and standard speed bump relations are modeled as dynamic systems and processed in a computerized simulation. In established simulation model, the speed bump form is assumed as road input and its cross section curve is polynomial. The optimization algorithm minimizes the vehicle oscillation when the vehicle passes over the speed bump within the range of determined speed limits and elevates the vehicle oscillation to a safe but higher pre-defined value when the vehicle passes over the speed bump with much higher speeds. Optimization is carried out by entering the required parameters to design optimization toolbox and the obtained simulation and optimization values provides different speed bump forms for different speeds.
