Learning Travel Time Distributions with Deep Generative Model [PDF]
The World Wide Web Conference, 2019 Travel time estimation of a given route with respect to real-time traffic condition is extremely useful for many applications like route planning. We argue that it is even more useful to estimate the travel time distribution, from which we can derive the expected travel time as well as the uncertainty. In this paper, we develop a deep generative model -

Adaptive Gaussian mixture model for identifying outliers in historical route travel times
IET Intelligent Transport Systems, 2023 The historical route travel time data contain a few outliers composed of subpopulations signifying unusual traffic conditions. These outliers compose the right tail of the distribution against the central part occupied by most normal travel times ...

Distributions of travel time variability on urban roads [PDF]
Journal of Advanced Transportation, 2011 SUMMARYReliability is an important factor in route, mode and also departure time choice analysis and is a key performance indicator for transport systems. However, the current metrics used to measure travel time variability may be not sufficient to fully represent reliability.
