Since their introduction the traditional speed bumps have been the main tool used by the traffic engineers for limiting the driving speed, particularly in the vulnerable traffic areas. Traditional speed bumps do work, but they also raise considerable safety and cost-related issues, including potential injuries of the passengers, adverse effects on the buses and damages to the overpassing vehicles. Additionally, the traditional speed bumps force vehicles to repeatedly slow down and speed up, which almost doubles the amount of the exhaust gasses and have high impact on the fuel consumption.
