| Abstract | The report presents the findings and conclusions of a study to develop an experimental design and analysis plan for field testing and evaluation of the accident reduction potential of a proposed new railroad grade crossing advance warning sign. Several alternative sampling frameworks were initially developed to determine which might offer the most efficient design in terms of required sample size. The cost of undertaking the field studies and analyses was then evaluated so that it could be compared to the expected value or utility of the information to be derived from the study. The results indicated that the proposed accident study would be both experimentally and economically impractical. It was therefore recommended that an accident study not be undertaken. Several policy options were then examined. |
