DETERMINATION OF OPERATING CRITERIA FOR THE INSTALLATION OF ADDITIONAL ELEMENTS IN THE ROAD CROSS SECTION

ERARBEITUNG VON EINSATZKRITERIEN FUER DIE ANORDNUNG VON ZUSAETZLICHEN ELEMENTEN IM STRASSENQUERSCHNITT

THE NUMBER OF TRAFFIC LANES AND - IN SOME CASES - THEIR DESIGN ARE DEPENDENT ON TRAFFIC LOADING AND, IN PART, ON TRAFFIC COMPOSITION. THE PARTS OF THE ROAD WHICH HAVE TO BE PROVIDED IN ADDITION TO THE TRAFFIC LANES ARE BASED ON VARIOUS OPERATING CRITERIA, FOR WHICH PRACTICAL, EASY TO USE INSTRUCTIONS ARE TO BE WORKED OUT. THE STUDY IS BEING UNDERTAKEN PARTICULARLY BECAUSE OF THE NEED TO REVISE THE RAS SPECIFICATIONS, GIVING INCREASED CONSIDERATION TO URBAN REQUIREMENTS.
