measure speed is at or below speed limit and
rises if the vehicle speed exceeds the limit.
Thus, the device rewards drivers who drive
the speed limit and discourages those who do
not. The technical issues involved in designing
the intelligent speed reduction device include
speed detection, speed bump mechanism, and
assurance of system reliability.
Speed bumps and speed humps are commonly
used “traffic calming” measures, which are
usually made from asphalt that is up to
six inches high and three feet wide. Such
rigid speed bumps are “dumb” and do not
respond to the traffic density, vehicular speed,
and emergency scenarios. Many traffic
fatalities have been attributed to rigid speed
bumps. They can cause vehicle damage and
contribute to pollution. As part of the Campus
2020 project, the smart speed reducer project
is aimed to encourage drivers to drive at or
below speed-limit on the university campus.
We propose to design a speed bump that
adjusts its “bump” according to the measured
speed of the driver; it should flatten if the
