NETWORK OR LOAD ORIENTATED DESIGN OF MOTORWAY JUNCTIONS - A DESIGN EXAMPLE

NETZ- ODER BELASTUNGSORIENTIERTE AUSBILDUNG VON AUTOBAHNKREUZEN - EIN ENTWURFSBEISPIEL

IN THE DESIGN OF GRADE SEPARATED MOTORWAY JUNCTIONS THE QUESTION ARISES OF WHETHER THE THROUGH CARRIAGEWAYS SHOULD FOLLOW THE HEAVY TRAFFIC STREAMS (LOAD ORIENTATED SOLUTION) OR WHETHER THEIR DIRECTION SHOULD RESULT FROM THE NETWORK FUNCTION (NETWORK ORIENTATED SOLUTION). TO MAKE A DECISION IT IS NECESSARY TO ASCERTAIN THE INDIVIDUAL TRAFFIC FLOWS, TO CHECK THE RELIABILITY OF THE TRAFFIC FORECASTS AND TO TAKE INTO CONSIDERATION THE DEVELOPMENT OF THE COMPLETE NETWORK. WITH THE AID OF AN EXAMPLE OF THE PLANNED MOTORWAY JUNCTION AT STUTTGART (A81 AND A8), THE INDIVIDUAL STEPS AND THE EVALUATION CRITERIA ARE DESCRIBED, FROM WHICH IT MAY BE SEEN THAT THE NETWORK ORIENTATED SYSTEM HAS THE ADVANTAGE. FOR THE PRESENT DEMAND STRUCTURE, RESULTS FROM THE TRAFFIC SURVEYS OF 1973 AND 1975 WERE AVAILABLE. THE FUTURE DEMAND STRUCTURE WAS STUDIED USING 6 FORECASTS FOR DIFFERENT STAGES OF THE CONSTRUCTION OF THE NETWORK. THE EFFECT OF THE DIFFERENT FORECASTS UPON THE CRITICAL AREAS OF EXITS, ENTRANCES AND INTERWEAVING WERE EVALUATED. THIS LED TO THE SELECTION OF THE NETWORK ORIENTATED SOLUTION. THE LANE FLOW PLAN FOR 1990 AND THE PLANS FOR THE CALCULATION OF THE NETWORK ORIENTATED AND LOAD ORIENTATED SOLUTIONS ARE PROVIDED.
