Pollution compared
NOISE
The average sound levels emitted by vehicles travelling at 50/60 km/h in a 12-15 m road:
(no. vehicles per hour / sound level);
100 v/h (63dB)
500 v/h (70dB)
1000 v/h (73dB)
2000 v/h (76dB) (source: Quid 2000)
Populations exposed to noise: In France around 7 million people (12.7%) are subjected
to a sound level of above 65 dB, taking a transport average.
10% of habitants are exposed to an excessive noise in inner Paris. In certain
areas, 20% of habitants are exposed to a sound level of more than 70 dB(source: Quid 2000)
These ugly statistics would drop by a significant
level if one removed all that could be transported via the waterways.
