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
