A software system was developed for a microcomputer to conduct bridge management system studies for local agency bridge systems. The software system was developed so that weighting factors and level-of-service goals were kept in separate data base files. This way, criteria could be easily changed without modifying the basic program. By evaluating one local county bridge system, it was demonstrated that microcomputers provided a good computing base for managing local bridge systems. The results of the bridge management system analysis showed excellent correlation with the independently developed bridge replacement program in that county. When differences occurred, they were justified when other factors were considered. A procedure was proposed for implementing a bridge management system at the local level. This approach encourages input from all involved parties in setting policy and level-of-service goals. Particular emphasis is placed on the importance of accurate and consistent bridge parameter data.
