The development and testing of an integrated sign ordering system (ISOS) framework are introduced. Based on advanced networking and database technologies and object-oriented and event-driven programming paradigms, this framework was built to assess the feasibility and effectiveness of implementing an information management system for the design, production, and application of traffic signs. By using this information system, data utilization can be automated locally and over the network among the district, the central office, and the sign shop that are involved in the ordering and production process of signs. Preliminary testing by using data from the Ohio Department of Transportation indicates that the ISOS model is feasible and practical. It enables accurate and reliable design data flows within the system and is very user friendly. With further enhancement to its functions, the ISOS model could be developed into an effective engineering tool for field applications.
