VEHICLE HANDLING TEST PROCEDURES-FINAL REPORT

AN HYPOTHESIS IS ADVANCED TO EXPLAIN THE RELATIONSHIP BETWEEN VEHICLE HANDLING PERFORMANCE AND HIGHWAY SAFETY. THE PROBLEM IS TO (1) IDENTIFY SAFETY RELEVANT PERFORMANCE QUALITIES, AND (2) DEVELOP PROCEDURES FOR THEIR MEASUREMENT. THE DESIGN AND OPERATION OF AN AUTOMATIC CONTROL SYSTEM TO MANIPULATE THE VEHICLE'S STEERING, BRAKING, AND ACCELERATING CONTROLS ARE DESCRIBED IN DETAIL. THE RESULTS OF SUPPLEMENTARY VEHICLE TESTS PERFORMED ESPECIALLY FOR THE PURPOSE AND THE OUTPUT OF A HYDRID COMPUTER STUDY INVOLVING OVER 1400 SIMULATION RUNS, ARE EMPLOYED TO HELP INTERPRET AND GENERALIZE THE BASIC DATA. THE REPORT HAS TWO APPENDICES. THE FIRST DESCRIBES AND ILLUSTRATES THE ANALYSIS OF VEHICLE-USAGE SURVEY DATA TO DERIVE REALISTIC RANGES OF SERVICE FACTORS-TIRE INFLATION PRESSURE AND VEHICLE LOADING- TO BE CONSIDERED IN AN EVALUATION OF VEHICLE PERFORMANCE. THE SECOND DESCRIBES THE HYBRID SIMULATION MODEL EMPLOYED IN THE STUDY, AND PRESENTS COMPARATIVE EXPERIMENTAL AND THEORETICAL RESULTS TO ILLUSTRATE THE DEGREE OF VALIDITY OF THE MODEL. /HSL/
