‘Noise radar’ in Paris will catch raucous cars and motorbikes

System promises to issue tickets automatically in attempt to address sound pollution in the city

Paris has switched on its first noise radar as part of a plan to fine loud motorcycles and other vehicles in one of Europe's noisiest cities.

The machine placed high on a street lamp-post in the 20th district in eastern Paris is able to measure the noise level of moving vehicles and to identify their licence plate.
