Reliability is defined in this report as consistency of travel times for a particular trip. Travelers tend to estimate how long a trip will take based on parameters such as distance, time of day, and their own experience. Impacts to the transportation network that cause unexpected delays introduce uncertainty in travel time reliability. The SHRP 2 Reliability focus area addresses reliability by developing specific procedures, monitoring programs, and exploring alternatives to traditional traffic management strategies. The L01 project focused on processes that directly affect network and travel time reliability, particularly those processes that enable operational functions and in which integration plays a significant part. The project identified the core of operations business processes within transportation management that had day-to-day influence over operations and network performance and, in turn, had positive impacts on travel time reliability.
