Fuzzy Travel Time Reliability with Uncertainty
2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009Fuzzy travel time reliability on road network is presented in the paper, which shows travelers’ expected travel time and tolerance to delay by membership function. In virtue of the stochastic users’ equilibrium model, the fuzzy travel time reliability is obtained under day-to-day variations in travel demand. A scenario-based analysis method is proposed

Origin–Destination-Based Travel Time Reliability
Transportation Research Record: Journal of the Transportation Research Board, 2017Travel time reliability (TTR) is an important performance indicator for transportation systems. TTR can be generally categorized as either segment based or origin–destination (O-D) based. A primary difference between the two TTR estimations is that route information is implied in segment-based TTR estimations.

Multistate Model for Travel Time Reliability
Transportation Research Record: Journal of the Transportation Research Board, 2010Travel time unreliability is an important characterization of transportation systems. The appropriate modeling and reporting of travel time reliability is crucial for individual travelers as well as management agencies. A novel multistate model is proposed for travel time modeling and reporting.

Multimodal travel choice determinants in context of travel time reliability
Proceedings of the Institution of Civil Engineers - Transport, 2023This study investigates the trends and determinants that dictate the state of multimodal transport by incorporating the effect of travel time reliability at different levels of service of traffic conditions. To account for the taste variation of commuters, a random parameter mixed logit model is used for the multimodal choice analysis.

The Reliability of Travel Time Forecasting
IEEE Transactions on Intelligent Transportation Systems, 2010Travel time is a fundamental measure in transportation, and accurate travel time forecasting is crucial in intelligent transportation systems (ITSs). Currently, many techniques have been applied to travel time forecasting; however, the reliability of the prediction has not been studied in these approaches.

Travel Time Reliability for Stockholm Roadways
Transportation Research Record: Journal of the Transportation Research Board, 2009In recent years, there has been an increasing awareness that travel time reliability, apart from expected travel time, is an important component of cost–benefit analysis, especially during congested traffic conditions. A common measure of travel time reliability is standard deviation, and it has been shown that this is a theoretically sound measure ...

Traveling Time Reliability in Sudden Events
International Conference on Transportation Engineering 2009, 2009Sudden events can make great influence on road network's ordinary operation. Travel time is an important parameter evaluating the performance of road network. The paper analyzes relationship between travel time and traffic flow on a road section, analyzes distribution rule of traffic flow on each routes in a road network and travel time reliability.

Travel Time Reliability Prediction Using Random Forests
Transportation Research Record: Journal of the Transportation Research Board, 2023The concept of travel time reliability was developed to quantify the variability in travel times. As travel time reliability measures are increasingly used in system planning and performance measurement processes at many transportation agencies, predicting travel time reliability measures has become critical.

Flow Breakdown and Travel Time Reliability
Transportation Research Record: Journal of the Transportation Research Board, 2009This paper proposes a methodology for online prediction of travel time reliability based on real-world measurements in light of the probabilistic character of traffic breakdown. A discrete time Markov chain is developed to represent the flow breakdown event.

Travel Time Reliability Measures Accommodating Scheduling Preferences of Travelers
Transportation Research Record: Journal of the Transportation Research Board, 2019Existing travel time reliability measures fail to accommodate scheduling preferences of travelers and cannot distinguish between the variability associated with early and late arrivals. This study introduces two new travel time reliability measures based on concepts from behavioral economics.
