Plan for the Nova Scotia Transportation Management Information System

The Nova Scotia Department of Transportation and Public Works (TPW) initiated a plan for an integrated decision support system to serve four business areas: pavement management, bridge management, traffic, and safety. Driving the plan is an ongoing effort to improve and streamline business processes across the Department. It is hoped that the new systems will strengthen and reinforce the improved organization and be implemented using commercial off the shelf applications. At the foundation of the plan is a business process model describing responsibilities and procedures as they are envisioned for the future. The model identifies data collection, condition analysis, policy development, and treatment selection processes that are divided along disciplinary lines within the Department. Cross-disciplinary processes of planning, prioritization, budgeting, funding allocation, and work tracking are also identified and described. The procedures surrounding each individual process form the basis of subsystem requirements, and also help to focus the reengineering efforts. Using the results of the business and use case models a conceptual design was developed for an integrated transportation management information system. This paper describes the business process and use case models for the pavements and bridge management systems. The complete TIMS will include safety, traffic and network expansion components operating within a common framework founded upon a common database and geographic information system.
