Abstract

The problem of providing improved design for roadway culverts is investigated through a twofold analysis: (a) examination of accidents on Texas highways and (b) presentation of a theoretical computation involving societal accident costs and a probability of impacts developed by the American Association of State Highway and Transportation Officials. The study findings indicate that culvert-related accidents are of minor significance in terms of overall accident occurrences. To achieve optimal accident reduction, it is essential that any enhancements to existing culvert designs be carefully considered. Recent research findings offer some insight into designs to mitigate the hazard potential of cross-drain and driveway culvert installations. The acceptance of any remedial measure must compare the cost associated with the recommended design with the cost involved in its required maintenance and the effect on performance due to terrain encountered in typical field installations. A list of proposed modifications to culvert design is provided to assist the designer in optimizing safety expenditures.
