Below is a calculation of real cost for an average old speed bump over 10 years.
Initial installation cost (speed bump, construction, signs…): | 1000 EUR |
Cost of wasted fuel: | 10 * 9600 = 96000 EUR* |
CO2 put into atmosphere: | 20,000 * 10 = 200 tons |
Time wasted: | 10*1500 – 15,000 Hours** |
Discomfort: | 17.3 million times a car is unnecessary ‘punished’** |
Noise: | medium impact*** |
Pollution (CO, NO, PM…): | big impact*** |
Slowing emergency vehicles: | medium impact**** |
Total/10 years: | 97,000 EUR + 15,000 hours lost |
*estimated fuel waste, typical speed bump 8000 liters, price 1.2 EUR/lit.
** 5000 cars/day on average, 95% driving below the limit, 1.5 people/car avg.
*** We do not have specific numbers for noise and pollution impact, but they are significant (pollution is decreased by at least 40% )
**** as the speed bumps are not put on emergency routes, the impact is minimized, but there is no safety on the streets
Our Smart bumps avoid all these negative effects. By avoiding the stop-start behavior, we provide constant speed of the vehicles, that minimizes the fuel consumption and pollution, and avoids the delay and congestion. As the majority of vehicles would go over flat smart bump, there will also be less noise.
By avoiding the negative effects, we are not only improving drivers’ experience and decreasing the pollution, but the great thing is that our smart bumps practically pay for themselves in few months, only from the fuel savings.
