abstract="The Danish Road Directorate has recently issued provisional specifications for marking traffic lanes of main roads beginning in 1984. Simultaneously recommendations on materials for, and maintenance of, marking were issued. Specifications and maintenance strategy are based exclusively on the functional requirements of the markings. It is expected that the introduction of the recommendations will result in a higher standard of marking and thus contribute to increased road safety.
