The Project is part of the Model Regions Electric Mobility Programme of the Federal Ministry for Transport, Building and Urban
Development (BMVBS). The programme’s funding budget, which runs from 2009 to 2014, is about 130 million Euro. It is financed
from the German government’s second economic stimulus package.

The actual reading
results from offsetting the A - weighted maximum levels
of different Runs.
This gives an absolute reading.
The height of the reading will be determined by
the measurement at the point P determined..

Volume reduction of approaching vehicles considerably higher than expected by
the Din standard measurement 362.
Main factors for vehicle noise emissions
-> Type of engine
-> Insulation of vehicles and active noise shaping
-> road conditions
-> number of start / stop operations.
Especially in delivery traffic (many start - stop operations) and small cars
considerable reductions are possible.
Less potential for middle class and upper class.
