A Method for Solving Reliability of Route Travel Time

open access: yesJournal of Function Spaces, 2020
In order to obtain an effective method for solving route travel time reliability, this paper proposes an effective new method to calculate travel time reliability using an independent link travel time function. Based on several months of historical data,

Learning Travel Time Distributions with Deep Generative Model [PDF]

open access: yesThe 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 -

Finding Most Reliable Path With Extended Shifted Lognormal Distribution

open access: yesIEEE Access, 2018
Travel time uncertainty may cause late arrival and impose a high penalty on travelers. There is a growing interest in modeling travel time uncertainty to optimize the reliability of travel time at the path and network level. Real data analysis finds that

Bayesian Nonparametric Model for Estimating Multistate Travel Time Distribution

open access: yesJournal of Advanced Transportation, 2017
Multistate models, that is, models with more than two distributions, are preferred over single-state probability models in modeling the distribution of travel time.

Heterogeneous Data Fusion Method to Estimate Travel Time Distributions in Congested Road Networks

open access: yesSensors, 2017
Travel times in congested urban road networks are highly stochastic. Provision of travel time distribution information, including both mean and variance, can be very useful for travelers to make reliable path choice decisions to ensure higher probability

Modeling Uncertain Travel Times in Distribution Logistics

open access: yesApplied Sciences, 2023
Uncertainty quantification is a critical aspect of distribution logistics, particularly unpredictable travel times caused by traffic congestion and varying transportation conditions. This paper explores the modeling of uncertainty in dealing with travel times in the context of distribution logistics using the collocation method.

Adaptive Gaussian mixture model for identifying outliers in historical route travel times

open access: yesIET 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 ...

A Reliability-Based Network Equilibrium Model with Adaptive Risk-Averse Travelers

open access: yesJournal of Advanced Transportation, 2018
In this paper, route free-flow travel time is taken as the lower bound of route travel time to examine its impacts on budget time and reliability for degradable transportation networks.

Modelling travel time distribution and its influence over stochastic vehicle scheduling

open access: yesTransport, 2019
Due to the paucity of well-established modelling approaches or well-accepted travel time distributions, the existing travel time models are often assumed to follow certain popular distributions, such as normal or lognormal, which may lead to results ...
