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 ...

Integrating fluctuations into distribution of resources in transportation networks
, 2009 We propose a resource distribution strategy to reduce the average travel time in a transportation network given a fixed generation rate. Suppose that there are essential resources to avoid congestion in the network as well as some extra resources.

Citywide Estimation of Travel Time Distributions With Bayesian Deep Graph Learning
IEEE Transactions on Knowledge and Data Engineering, 2023 Estimation of road link travel time serves a critical role in intelligent transportation operation and management. Due to the uncertainty nature contributed by the volatile traffic, travel time estimates are better described by probability distributions ...

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

Catchment mixing processes and travel time distributions [PDF]
Water Resources Research, 2012 This work focuses on the description and the use of the probability density functions (pdfs) of travel, residence and evapotranspiration times, which are comprehensive descriptors of the fate of rainfall water particles traveling through catchments, and provide key information on hydrologic flowpaths, partitioning of precipitation, circulation and ...

Modelling travel time distribution and its influence over stochastic vehicle scheduling
Transport, 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 ...

The value of reliability [PDF]
, 2007 We derive the value of reliability in the scheduling of an activity of random duration, such as travel under congested conditions. We show that the minimal expected cost is linear in the mean and standard deviation of duration, regardless of the form of ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.
