In a previous publication, Traffic Gridlock: The Real Deal or a Pile of Nonsense?, I reported on a study which applied several research procedures to examine media stories and Google search items containing the terms “traffic gridlock” or “gridlock” implying traffic gridlock. The objective was to ascertain whether the media stories and Google items establish that traffic gridlock is a real deal matter, or whether the stories and items contribute to a pile of nonsense. The finding was that 99% of the stories and items belong in the nonsense pile.
And therein lies a puzzle: How is it that “traffic gridlock” enjoys considerable media and Google popularity, but little to no evidence demonstrating the occurrence of “traffic gridlock” accompanies the vast majority of stories and Google entries? In this report I explore one possible explanation, and the associated implication for public policy. That is, traffic gridlock” is a bad, mis-leading metaphor which has been accepted and promulgated by some parties as a truth for which no proof exists and none is needed. And, the associated cause-effect relationship that I comment on is that a bad, mis-leading metaphor is a bad, mis-directed basis for setting public policy.
To support this explanation I introduce the good metaphor “traffic blockage”, and use it as a means to discredit and dismiss the traffic gridlock metaphor which I believe erroneously distorts understanding the role of motor vehicle congestion in urban places, and obscures/confounds the appropriate ways and means of considering and addressing urban motor vehicle congestion. And, as per the initial paper, an invitation is extended to anyone who has traffic gridlock evidence: please call it to my attention at the earliest so that I can adjust my thinking and revise my papers.
