New European handbook on the integration of noise in road planning

The Conference of European Directors of Roads (CEDR) launched the ON-AIR project in 2013, the aim of which was to develop a noise assessment manual for all aspects of road planning and maintenance. The resulting “ON-AIR-Handbook” shows ways of taking into account the noise reduction for the three most frequent planning situations:

1. Planning of new roads and highways
2. Conversion and extension of existing roads and highways
3. Maintenance and operation of existing roads and highways

The project was conducted by the Danish Vejdirektoratet (project management) together with Transportøkonomisk institutt (Oslo) and Lärmkontor GmbH (Hamburg), who handled the manual. The ON-AIR project was financed by six European public road transport authorities.

In the first part of ON-AIR a systematic analysis of the current planning practice in Europe took place. In addition, innovative ideas were identified and discussed in Hamburg at LÄRMKONTOR GmbH as part of a future workshop involving high-ranking European experts from road and environmental authorities as well as from consulting offices.

The manual provides tools for integrating approaches to noise reduction in different areas of road planning and maintenance. It contains a collection of over 30 illustrative – also interactive – practical examples.


Last week a network meeting of Lärmkontor as well as our partner offices ARGUS , LK Argus Berlin and Kassel as well as konsalt took place to intensify the cooperation of the offices in the future. We also discussed the joint services offered in the areas of traffic planning, road planning, construction preparation and monitoring, immission protection, climate protection concepts, urban development, participation and events.


LÄRMKONTOR GmbH supports IBA Hamburg GmbH during the first planning phase of the “Oberbillwerder” area in the east of Hamburg. In addition to sound engineering investigations and shadow predictions, we also supervise the vibration assessments. In addition to living space, facilities for work, education, leisure, sports and recreation are to be created on some 120 hectares.
