Contraflow bus lanes seem to produce a never ending succession of accidents involving pedestrians. An understandable reaction is that pedestrians are careless and that more visible indicators of the potential danger is an appropriate measure. This leads to the 'Symptomatic Solution' - but unfortunately accidents are not usually stopped by symptomatic solutions. Another but potentially far more costly and time-consuming approach is available: investigating a fundamental solution. Recent findings in cognitive science have shown that often repeated actions (like looking to the right when crossing the street) are phisically represented in our brains - see George Lakoff and Mark Johnson's book Philosophy in the Flesh. It seems that looking in the wrong directon is a default setting in our brain that is almost impossible to correct. The fundamental solution must deal with the implication of this and any other reasons that contribute to the accidents. In the town where I live, and surely in many other cities, contraflow bus lanes are still in operation - here, I'm sure, Systems Thinking could help and inform public policy.
