TECHNIQUE FOR THE INVESTIGATION OF SCHEME BENEFITS IN LARGE-SCALE TRANSPORT NETWORKS

THIS PAPER DESCRIBES A NEW TECHNIQUE, DESIGNED TO PERMIT THE EVALUATION OF INDIVIDUAL PROJECTS ON THE OVERALL TRAFFIC PATTERN WHILE STILL RETAINING THE LEVEL OF DETAIL AVAILABLE FROM A FULL-SCALE MATHEMATICAL MODEL OF TRAFFIC FLOW. THE AIM HAS BEEN TO PRODUCE A CHEAP AND EASY-TO-USE TECHNIQUE, CAPABLE OF PRODUCING SUBSTANTIALLY THE SAME RESULTS AS A STANDARD MODEL. THE TECHNIQUE USES NEWLY DEVELOPED COMPUTER ALGORITHMS WHICH SHORT-CUT THE FULL-SCALE MODEL BY FORECASTING THE CHANGES IN AN EXISTING TRAVEL PATTERN RESULTING FROM THE INFLUENCE OF A PARTICULAR PROJECT. INITIAL TESTS SUGGEST THAT APPROACHING THE PROBLEM IN THIS WAY CAN SAVE UP TO 70 PERCENT OF THE COMPUTING TIME AND COSTS INVOLVED IN THE USE OF A STANDARD MODEL FOR THE EVALUATION OF INDIVIDUAL PROJECTS. THE TECHNIQUES AS DESCRIBED HEREIN ENVISAGED AS A TOOL FOR AIDING STRATEGIC INVESTMENT DECISIONS.
