Transportation Research Record: Journal of the Transportation Research Board, 2003
Vehicle reidentification was investigated as a method for deriving travel time and travel time distributions with loop and video detectors. Vehicle reidentification is the process of tracking vehicles anonymously from site to site to produce individual vehicle travel times and overall travel time distribution.

Travel Time Distribution under Interrupted Flow and Application to Travel Time Reliability
Transportation Research Record: Journal of the Transportation Research Board, 2014The travel time distribution under interrupted flow based on radio frequency identification–detected data is analyzed. The urban road network studied is in downtown Nanjing, Jiangsu Province, in China, where video cameras and radio frequency equipment are installed at some arterial links to acquire traffic flow data including vehicle type, passing time,

Estimating Travel Time Distributions by Bayesian Network Inference
IEEE Transactions on Intelligent Transportation Systems, 2020Travel time estimation is an important aspect of intelligent transportation systems (ITS). In urban environments, travel times can exhibit much variability due to various stochastic factors. For this reason, we focus on estimating travel time distributions, in contrast to the more commonly studied estimation of mean expected travel times.

An Inhabitant Travel Time Distribution Model
Traffic and Transportation Studies 2010, 2010In order to study the law of inhabitant travel time distribution, the model for the constraints of utilities and targeted information entropy maximization was proposed. Probability theory of Logit model and maximum information entropy principles were used to build the planning model.

The Development and Calibration of a Model for Urban Travel Time Distributions
Journal of Intelligent Transportation Systems, 2013Travel times on the urban roadways are intrinsically uncertain. For known traffic conditions, a wide travel time distribution can be observed. Among all the components of travel times, delays incurred when approaching intersections constitute a large part of travel times that vehicles experience in urban trips. In this article, a model is presented for

Travel time statistical modeling with the Halphen distribution family
Journal of Intelligent Transportation Systems, 2017ABSTRACTThis article introduces the Halphen distribution family for modeling travel time distributions and their reliability on single road links. This probability family originally used in hydrology has a set of relevant characteristics. It is composed of three probability distribution functions for which the mathematical properties are described here.

Mixture Models for Fitting Freeway Travel Time Distributions and Measuring Travel Time Reliability
Transportation Research Record: Journal of the Transportation Research Board, 2016Travel time reliability has attracted increasing attention in recent years and is often listed as a major roadway performance and service quality measure for traffic engineers and travelers. Measuring travel time reliability is the first step toward improving it, ensuring on-time arrivals, and reducing travel costs.

Trip travel time distribution prediction for urban signalized arterials
16th International IEEE Conference on Intelligent Transportation Systems (ITSC 2013), 2013Travel time prediction is a challenge, especially if we consider urban trips. For freeways well-known models for traffic flow and speeds are applicable, e.g., based on physical models inspired by hydrodynamic or statistical models ranging from more conventional to more advanced AI approaches.

Evaluating travel time distributions of macroporous hillslope
2020<p>Residence and travel times of water in headwater catchments and hillslopes represent important descriptors of hydrological regime. In this study, travel time distributions were evaluated for a montane forest hillslope site using a two-dimensional dual-continuum model.
