REDUCING RUBBERNECKING. I posted here about the enormous costs in time and other resources that are imposed by traffic jams and argued that less effort is made to reduce congestion costs because those costs to motorists are not measured. Annalisa sent me this article on the BBC news website which describes how Britain is using roadway screens to hide accident scenes and reduce rubbernecking. There is a photo of a deployment of screens accompanying the article. Each set of screens costs 22,000 pounds. I think that the benefits of the screens will greatly outweigh the costs, even though the benefits will be hard to measure.
