Integrating Reliability into Transportation System Management – New Approaches for Linking Planning & Operations
Posted: 10/28/2019

The Strategic Highway Research Program (SHRP) explored and demonstrated the significance of travel time reliability in understanding and enhancing the role of transportation operations in transportation system management. The report, "Integrating Reliability into Transportation System Management", documents a project led by the Federal Highway Administration (FHWA) Office of Operations to integrate consideration and analysis of travel time reliability into the linkage of planning and operations. Its intent was to evolve the state of the practice by building a methodology supported by the travel time reliability data and analysis tools developed under the SHRP2 program. The project was motivated by the need to connect system-level, goal and objective-setting in the transportation planning process and operations planning that occurs among operators. Long-range transportation planning is typically not linked to detailed, tactical operations decisions made at the corridor or network level. A primary objective of this project was to develop and demonstrate a framework or methodology for integrating travel time reliability concepts and analysis in systems management, operations, systems planning, and programming. The project also demonstrated how this framework can be used to connect planning-level reliability goals and objectives to operational objectives and transportation systems management and operations (TSMO) strategies and tactics. The framework will likely be useful in the integration of automation and other emerging technologies into the management and operations of the national roadway network in the context of an increasingly multimodal surface transportation system.
