FACTOR ANALYSIS OF ROADWAY AND ACCIDENT DATA

THIS REPORT IS A FURTHER ANALYSIS OF DATA REPORTED BY SCHOPPERT. IN THAT STUDY, A NUMBER OF FEATURES CHARACTERISTIC OF UNIT LENGTHS OF OREGON TWO-LANE RURAL HIGHWAYS WERE RELATED TO THE OCCURRENCE OF ACCIDENTS. MULTIPLE REGRESSION EQUATIONS WERE OBTAINED TO PREDICT WHERE ACCIDENTS WOULD OCCUR. THE DATA WERE STRATIFIED ACCORDING TO ADT AND GEOGRAPHY. THE PRESENT ANALYSIS SOUGHT TO MAKE APPARENT ADDITIONAL RELATIONSHIPS AMONG THE ROADWAY FEATURES WHILE COMPRESSING THE RESULTS INTO A SMALL NUMBER OF MORE UNIVERSAL NOTIONS. /AUTHOR/
