After the successful implementation of a pavement management information system (PMIS) for a district road network the Mississippi Department of Transportation undertook a project to extend the system to the state network of more than 12,000 mi. An overview of systems development and the major products is presented. The system incorporates a number of microcomputer programs for data management functions, user interface, analysis, and reporting. The system was developed by using the FOXPRO data base software. Four major subsystems are identified: (a) a pavement management system inventory and monitoring data base, (b) condition data analysis accomplished through interface program, (c) a maintenance, planning, and budgeting (MPB) program, and (d) a priority ranking of rehabilitation projects. The condition data are collected with automated equipment. The raw condition data are used to calculate (a) distress quantities by severity in each section and (b) two composite measures, visual pavement condition evaluation rating and pavement condition rating. The MPB program selects two alternative strategies if the road condition warrants major maintenance activity. It also calculates the agency cost and vehicle operating cost. The fourth subsystem ranks the pavement network, relying on traffic volume, condition, and functional classification, to produce a list of projects for the annual work program. Pavement management reports can be summarized for the network as a whole, each district, each county, or individual sections.
