SAVING MORE CYCLISTS

THIS REPORT EVALUATES THE PATTERNS OF INJURY SUSTAINED IN MOTOR CYCLE COLLISIONS IN SOUTHERN CALIFORNIA. THE SOURCES OF INJURY ARE THE MOTORCYCLE, THE OBJECT STRUCK AND THE ROAD SURFACE. 127 MOTOR CYCLE CRASH PARTICIPANTS WERE STUDIED. 25% OF THESE WERE FATALLY INJURED AND 58% HAD SEVERE TO CRITICAL INJURIES. CRASH VICTIMS ARE CATEGORISED INTO GROUPS OF NON-EJECTED, EJECTED AND DEFLECTED OCCUPANTS. 83% AND 80% OF THE NON-EJECTED AND EJECTED OCCUPANTS RESPECTIVELY RECEIVED SEVERE TO FATAL INJURIES, AND 66% OF THE DEFLECTED OCCUPANTS RECEIVED SEVERE TO CRITICAL INJURIES. TWO PRINCIPAL MODES OF EJECTION WERE NOTED AND THESE ARE DISCUSSED. ANALYSIS OF THE INJURY PATTERNS INDICATED THAT HEAD INJURIES WERE MOST FREQUENT FOLLOWED BY LEG AND CHEST INJURIES RESPECTIVELY. THE SEVERITY OF INJURIES SUSTAINED BY OPERATORS AND PILLION PASSENGERS WAS COMPARED. OPERATORS TEND TO PROTECT PASSENGERS IN FRONTAL IMPACTS. 24 OF THE 127 MOTORCYCLISTS WORE CRASH HELMETS. THE STUDY CONCLUDES THAT PREDICTABLE INJURY PATTERNS HAD BEEN ESTABLISHED AND THESE COULD BE USED IN FUTURE MOTOR CYCLE DESIGN. A SPACE-FRAME CONCEPT WITH A DEFLECTING RAIL TO PROTECT THE LEGS, AND AN ENERGY-ABSORBING STRUCTURE FIXED TO THE FORKS TO CARRY AN AIRBAG, WHICH LIMITS FORWARD IMPACT PITCH, ARE THE SUGGESTED DESIGN IMPROVEMENTS.
