摘要：	The Indiana Bridge Management System (IBMS) was developed to organize, present and analyze information related to the maintenance and improvement of highway bridges. To recommend improvement alternatives, prepare cost estimates and optimize allocation of available funding, a large database containing information from bridge, road, and traffic inventories must be presented in an accessible and descriptive form. The IBMS has been in development for over a decade and the present paper discusses some of the enhancements made in the project selection module, including the revision of the agency cost model, the incorporation of a user cost model, and the updating of bridge condition transition probabilities. A graphical user interface was also incorporated for the IBMS to make interaction with data quick, easy and efficient. Whether viewing inventory or evaluating analysis results, presentation in chart, graph, and report format promotes good decision making. An example using the 1998 state bridge database is presented. An evaluation of the impact that budget levels have on the quality of the Indiana state bridge network is also included.
