RESEARCH - Effectiveness of Children at Play Signs
The Wisconsin Department of Transportation commissioned a report to update it's policies regarding roadside warning signs related to children. From the report summary:
There is no evidence that special warning signs of this sort reduce driver speeds or crash rates. This is the unanimous conclusion of the many credible sources we located on this topic. This claim is supplemented by a number of often-cited “common sense” observations th at such signs do not give clear and enforceable guidance to drivers, provide a false sense of security to parents and children that may increase risk, expose the government to liability, give the false impression that areas without such signs do not have children, represent an unnecessary cost that then propagates as additional signs are requested and violate the principle that signage should be based on engineering, not political, decision making.
