Travel through time: the story of research on travel time reliability

Transportmetrica B: Transport Dynamics, 2013
This paper provides a review of research on the concepts and application of travel time reliability and on the underpinning research on travel time variability. It charts the development of the topic from beginnings concerned with exploring the possible extent of variability in travel times through to the current interests in the specification of ...

The Reliability of Travel Time Forecasting

IEEE Transactions on Intelligent Transportation Systems, 2010
Travel 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.

Reliability of Travel Time

Transportation Research Record: Journal of the Transportation Research Board, 2008
The reliability of the travel time on a route is widely regarded as one of the dominant factors affecting the route and departure time choices of travelers. There is still a lack of consensus on the quantitative measures that best reflect travel time reliability.

Multi-state travel time reliability model: Impact of incidents on travel time reliability

2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC), 2011
This paper attempts to quantify the impact of traffic incidents on travel time reliability using a newly proposed multi-state travel time reliability model. Given that the multi-state travel time reliability model provides significantly better fits when compared to using a single-mode density function, it is possible to quantify the incident impacts ...

Fuzzy Travel Time Reliability with Uncertainty

2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009
Fuzzy 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

Estimating Path Travel-Time Reliability

2006 IEEE Intelligent Transportation Systems Conference, 2006
The estimation of path or trip travel-time reliability is critical to any advanced traveler information system. The state-of-practice procedures for estimating path travel-time reliability assumes that travel times follow a normal distribution and requires a measure of trip travel-time variance.

Travel time reliability with boundedly rational travelers

Transportmetrica A: Transport Science, 2017
ABSTRACTThis paper presents a definition of boundedly rational confidence level (BRCL) which is the probability that a trip arrives within the shortest travel time budget plus the acceptable travel time difference (i.e. boundedly rational threshold). Using the method of data fitting, boundedly rational threshold is estimated.

Travel Time Reliability with Risk-Sensitive Travelers

Transportation Research Record: Journal of the Transportation Research Board, 2002
In recent empirical studies on values of time and reliability, many have suggested that travelers are interested not only in travel time saving but also in reduction in travel time variability. Variability introduces uncertainty for travelers such that they do not know exactly when they will arrive at their destination. Thus, it is considered as a risk

Transit Travel Time Reliability

Transportation Research Record: Journal of the Transportation Research Board, 2015
Transit agencies traditionally have used vehicle movement to assess service quality. However, new technologies such as automatic fare collection systems, automatic passenger counters, and automatic vehicle location devices are giving agencies a wealth of data from which critical insights can be gained about customer experience.

The impact of travel time variability and travelers’ risk attitudes on the values of time and reliability

Transportation Research Part B: Methodological, 2016
Abstract In this paper, we derive implementable measures of travelers’ willingness to pay to save travel time ( vot ) and to improve the reliability ( vor ) of a given trip. We set out a simple microeconomic model of transport mode choice in which each trip is fully characterized by its price and the statistical distribution of its random travel ...
