A CASE HISTORY STUDY OF FATAL ACCIDENTS

AN ANALYSIS WAS MADE OF 1715 FATAL TRAFFIC ACCIDENTS REPORTED BY EIGHT STATES AND EIGHT CITIES FOR THE YEAR 1936. AMONG THE FINDINGS WERE THE FOLLOWING: THE MEDIAN AGE OF THE PEDESTRIANS KILLED VARIED FROM A HIGH OF 65 FROM 5 TO 6 A.M. TO A LOW OF 7 DURING THE AFTERNOON. WHEN AN INDEX OF THE PEDESTRIAN DEATH RATE IS COMPUTED ON A POPULATION BASIS, THE AGE GROUP 15 TO 19 HAS THE BEST RECORD WITH AN INDEX OF 0.19 WHILE THE GROUP 75 TO 79 HAS THE WORST RECORD WITH 6.10. THE INDEX FOR OLDER PERSONS WAS FOUND TO BE LOWER OR HIGHER BUT THE NUMBER OF CASES WAS LIMITED. COMPARED TO ALL CAUSES OF DEATH, TRAFFIC IS MOST SERIOUS FOR PEDESTRIANS OF 5 TO 9 WITH AN INDEX OF 11.76. IT IS LESS SERIOUS THAN THE AVERAGE FOR PERSONS UNDER 5 YEARS OF AGE AND FOR THOSE 60 OR OVER. WHERE DATA WERE AVAILABLE 54.3 PER CENT OF THE VEHICLES WERE 4 YEARS OLD OR LESS. ONLY 55.1 PER CENT OF ALL VEHICLES WERE DRIVEN BY THE OWNER. FRIENDS OF THE OWNER DROVE 18.0 PER CENT AND EMPLOYEES OF THE OWNER 18.3 PERCENT OF THE CARS. THE MEDIAN AGE OF ALL DRIVERS WAS 30. THE MEDIAN AGE OF THE DRIVER WHEN AN OWNER WAS 36.5, WHEN AN EMPLOYEE 30.0 AND WHEN A FRIEND OF THE OWNER 26.6 YEARS. ONE-TENTH OF THE DRIVERS WERE 50 OR OVER. WHEN AN INDEX OF THE ESTIMATED MILEAGE DRIVEN PER FATAL ACCIDENT FOR EACH AGE GROUP IS COMPUTED IT INDICATES THAT THOSE 19 AND UNDER HAD THE POOREST RECORD WITH AN INDEX OF 0.29 WHILE THOSE 50 TO 59 HAD THE BEST RECORD WITH AN INDEX OF 1.67. THE PROBABILITY OF A DRIVER BEING KILLED INCREASES MATERIALLY WITH AGE. ONLY 10.7 PER CENT OF THOSE UNDER 20 WERE KILLED WHILE 38.1 PER CENT OF THOSE 70 AND OVER DIED AS A RESULT OF THE CRASH. DRINKING WAS REPORTED FOR 1.16 PER CENT OF THE OPERATORS OF PASSENGER CARS AND 4.1 PERCENT OF THE OPERATORS OF COMMERCIAL VEHICLES. /AUTHOR/
