Ms. W and her family contracted Century Driving school to perform a Driver Competency Assessment in an effort to benchmark her driving abilities for future decision making.
All drivers are scored on 4 discreet variables: speed, headway, junctions, vehicle control, and two composite ones:dynamic time management and dynamic space management. Overall Ms. W’s driving was in the low average range.Drivers can use either space or time to control their environment. Ms. W uses time more effectively than space (DSM - dynamic space management and DTM - dynamic time management). Both time and space were in the averagerange. Ms. W was in the average range on junctions (JUN - junctions; understanding and use of the road system). On headway (HEA - headway; interaction with other road users) Ms. W scored below average. Ms. W was in the average range on speed (SPD - appropriateness of speed choices for road and traffic conditions). On vehicle (VEH - vehicle handling skills) Ms. W scored above average. Overall this driver's scores were relatively consistent on individual measures but less consistent between all measures taken suggesting that there are areas that could easily be improved that would raise her driving skill given that she scored higher on some variables.
Task Loading Conditions:
During the drive Ms. W was scored while driving normally, while following a set of written navigational instructions and pointing out a predetermined set of addresses and while counting backwards by threes. Ms. W showed no difference between driving normally and driving while wayfinding (multitasking), suggesting this driver has developed some coping strategies to deal with competing demands. Ms. W showed no difference between driving normally and driving while counting backwards (internal distraction) suggesting that Ms. W has developed some control over her allocation of attentional resources.
While each segment was approximately three minutes long, some segments were more complex than others based on a predetermined set of criteria. Ms. W showed no differences between driving in complex and simple environments suggesting that she can handle both complex and simple driving situations equally poorly.
Ms. W is a low average driver who could easily raise her overall driving performance. This driver should undergo some remediation to raise her overall safety margins as found in the driver competency assessment across all areas of driving. This driver should be re-evaluated upon completion of remediation.
