The ban on truck-transit traffic of scenario 1 (which was implemented in 2006 in the frame of clean air plan of the regional capital Stuttgart) is demonstrable effective and does reduce the traffic work and noise exposure within the urban area of Stuttgart. 2. The truck restrictions being implemented within the districts of Vaihingen and Zuffenhausen are able to (further) reduce the noise exposure within city boundaries of Stuttgart 3. The improvement of the noise situation within the city however brings forth a worsening for the surrounding communities. 4. The point balance of the noise exposure is not positive all over, i. e. relocation of heavy load that is enforced by the bans on transit traffic may lead to an increase of the overall noise exposure. 5. Bans on truck traffic may be reasonable as a part of a package of measures if negative effects through relocation can be reduced or compensated with complementary measures. Final Results Deliverable D5.10. Stuttgart validation site – Town planning (trucks) Performance report of applied measures - Stuttgart will be available at March 2008 on QCity website.
