15.3.2.5 Emerging MOEs
New MOEs have recently been introduced to B/C analysis to evaluate the effectiveness of emerging TSMO strategies: travel time reliability, incident-related delay, and consumer surplus. These emerging MOEs often provide more justification for TSMO projects, as these MOEs are the focus of many operations deployments.
- Travel time reliability is the variability in travel times caused by both nonrecurring and recurring congestion sources.
- Incident-related delay includes factors that relate to a facility’s capacity.
- Consumer surplus refers to the difference between the amount users are willing to pay in terms of travel costs, including time and money, and how much they pay. Consumer surplus is usually used in the assessment of travel time savings.
