초록

In forklift-related accidents, two representative accident types, jammed and impact, were often caused by obstructed view. Around-view monitoring systems (AVM), commonly used in passenger cars was expected to resolve the obstructed view problem in forklifts. This study aimed to assess their potential benefits in forklift safety. By driving a forklift with the around-view monitoring system (AVM) and the forklift without the AVM, the braking times were measured and compared. The controlled test was conducted with eight drivers, each performing 32 trials (16 with AVM, 16 without AVM) involving forward and backward driving. Braking times were measured in response to one of eight lights switched on, which were positioned along the predetermined path. As a result, no significant difference was observed in average braking times depending on the AVM condition. However, outlier analysis revealed twice as many outliers in test condition without AVM, compared to the condtion with AVM. Therefore, around-view monitoring systems in forklifts could help reducing the number of unrecognitions, thereby preventing forklift-related accidents from obstructed view.
