ABSTRACT
Speed bumps are commonly used to control the traffic speed and to ensure the safety of pedestrians. This paper proposes
a novel speed bump energy harvester (SBEH), which can generate large-scale electrical energy up to several hundred
watts when the vehicle drives on it. A unique design of the motion mechanism allows the up-and-down pulse motion to
drive the generator into unidirectional rotation, yielding time times more energy than the traditional design. Along with
the validation of energy harvesting, this paper also addresses the advantages of this motion mechanism over the
traditional design, using physical modeling and simulation. Up to 200 watts electrical peak power in one phase of threephase generator during in-field test can be regenerated when a sedan passage car passes through the SBEH prototype at 2
km/h.

CONCLUSIONS
An effective design of energy harvesting speed bump is proposed. A prototype and in-field test by driving a vehicle
passing by are investigated. High power up to 200 W in one phase out of three-phase generator can be achieved, which is
much higher than the similar research in the literature. Modeling of the speed bump energy harvester and its interaction
with the vehicle model are also explored. The simulation of dynamic performance and the predicted electrical energy
harvesting when a vehicle passing by the speed bump energy harvester is carried out and compared with experimental
results, which validate the effectiveness of the proposed design.. By comparing areas under the curve of power
generated by MMR based harvester and the traditional electromagnetic harvester, we find that MMR based harvester
generates about 4-5 times more energy, which demonstrates it advantages over traditional one for energy harvesting
from the pulse-like excitations. The presented novel speed bump energy harvester and it compact structure can
conveniently replace the existing traditional speed bumps with less impact to the dynamics of the passing vehicles.
The proposed speed bump energy harvester.is expected to provide sufficient electricity for many road side devices like
signs, monitoring sensor and so on, which provide a cost-efficient energy source to supply electricity to intelligent
transportation system especially in the areas where power grid cannot be accessed economically.
