Discussion – conspicuity issue or cognitive failure?

SUMMARY – visual salience and cognitive conspicuity have both been investigated as potential causes of collisions between cars and PTWs… the conspicuity theory is widely accepted at face value… but there is no compelling statistical evidence that shows a reduction in collisions resulting from ROWV at intersections… as the SMIDSY collision happens worldwide in hugely different driving regimes, the implication is that the crashes are a ‘human factors’ problem, NOT a conspicuity issue… ‘Think Bike’ campaigns have limited effectiveness… the most effective option is likely to be improving rider understanding of drivers’ visual perception issues and cognitive problems, helping the rider adopt a better defensive riding strategy at intersections…
