Many transportation agencies explicitly recognize the idea that we can't build our way out of congestion. However, few state departments of transportation (DOTs) or local government transportation entities have focused effectively on how to continue to fulfill their mobility mission in an environment of capacity and financial constraints. If the full-service potential of an investment in an existing network (especially the freeway network) is to be realized, then state DOTs and local and regional transportation entities, together with their partner public safety agencies (PSAs), must move beyond capacity provision and maintenance to engage in active systems operations and management (SO&M) of the networks available capacity, including aggressive minimization of disruptions. The SHRP 2 Reliability focus area addresses the root causes of unreliable travel and identifies the role of performance measures, strategies, planning integration, and institutional issues related to supporting improved reliability. The L06 project focuses on nonrecurring congestion (NRC) as the principal source of delay and unreliability on the nation's roads. SO&M is defined by a set of conventional strategies that focus on responding to various causes of the unpredictable but highly disruptive losses of service associated with NRC.
