12 Chapter 1 presented and discussed the six primary sources of nonrecurrent congestion. Research in SHRP 2 Project L07 addressed these sources of unreliable travel times by identifying various design treatments that may be considered by highway agencies to reduce nonrecurrent congestion.

13 evolution of research approach for traffic Operational analysis The research team's original concept for Project L07 was that delay measures (i.e., vehicle hours of delay) for specific design treatments for nonrecurrent congestion would be obtained through a combination of the following: • Direct calculation of performance measures from field data • Deterministic analysis techniques (primarily those of the Highway Capacity Manual [2]

14 Design Guide The Design Guide catalogs the design treatments considered in this research, providing planners, designers, operations engineers, and decision makers with a toolbox of possible options for addressing nonrecurrent congestion through design treatments. The Guide begins with an introduction to nonrecurrent congestion and reliability, a discussion of the six main causes of nonrecurrent congestion, and a basic explanation of how the reduction of delay and the improvement of reliability can be valued in economic terms.
