Quiet City Transport (QCITY)

EU-project: research, technological development and implementation of innovative concepts for quieter cities

Noise reduction potentials of local truck routing concepts

Markus Petz ACCON Czech Republic, February, 19th 2008 Question within the project

How big is the noise reduction potential of local truck-routing and truck-restrictions respectively? How big are side effects?

Object: Quantification of the impact of measures within the agglomeration of Stuttgart

SP5 - Design and Final detailed design of selected solutions implementation at Implementation and validation of solutions in validation sites cities concerned. Selection of validation sites for dissemination and promotion purposes. Basis

Scenario for the evaluation of the combination of all restrictions Evaluation of the scenarios

Course of action 1. mapping of the different traffic scenarios with a noise calculation program 2. calculation of noise maps and facade levels at residential buildings for all scenarios 3. people exposure statistics (in 1-dB-classes) and aggregation in 5 dBclasses for all scenarios 4. statistics of the area exposed to levels in 5-dB-classes for all scenarios 5. „Noise Score“ – analysis for all scenarios Results: Change of traffic performance - cars
