OML-Highway is a user-friendly GIS-based model for assessment of air quality along motorways and other main roads in open terrain. A common application of OML-Highway is for assessment of air pollution in environmental impact assessments of new major roads or major alteration of existing roads. OML-Highway has been integrated into SELMAGIS, a GIS environment developed by Lohmeyer GmbH & Co. KG, Germany.

SELMAGIS is a framework which is used for running various dispersion models, including OML-Highway. It requires the GIS software ArcMap marketed by the company ESRI.

The present user guide provides a brief introduction to OML-Highway and to the central concepts in the model. It further describes the procedure and requirements for installation.

A central part of this user guide is the chapter Working through the menus, which gives a detailed description of the various menus and their application.

A detailed description of the various files handled in a OML-Highway project is provided in Appendix to the report.
