Synthesizing Route Travel Time Distributions from Segment Travel Time Distributions

Transportation Research Record: Journal of the Transportation Research Board, 2013
This paper examines a way to synthesize route travel time probability density functions (PDFs) on the basis of segment-level PDFs. Real-world data from I-5 in Sacramento, California, are employed. The first finding is that careful filtering is required to extract useful travel times from the raw data because trip times, not travel times, are observed (

An Inhabitant Travel Time Distribution Model

Traffic and Transportation Studies 2010, 2010
In 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.

Estimation of urban route travel time distribution using Markov chains and pair-copula construction

Transportmetrica B: Transport Dynamics, 2019
Route travel time information is essential for better travel planning, traffic guidance and congestion avoidance. An available way of representing such information is the estimation of travel time distribution (TTD).

Minimum Sampling Size of Floating Cars for Urban Link Travel Time Distribution Estimation

Transportation Research Record, 2019
Despite the wide application of floating car data (FCD) in urban link travel time estimation, limited efforts have been made to determine the minimum sample size of floating cars appropriate to the requirements for travel time distribution (TTD ...

Vehicle Reidentification as Method for Deriving Travel Time and Travel Time Distributions: Investigation

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.

Estimation of Route Travel Time Distribution with Information Fusion from Automatic Number Plate Recognition Data

Journal of Transportation Engineering, Part A: Systems, 2019
Route travel time varies with vehicles and traffic demand. Besides the average route travel time, route travel time reliability in the form of travel time distribution is indispensable.

Mixture Models for Fitting Freeway Travel Time Distributions and Measuring Travel Time Reliability

Transportation Research Record: Journal of the Transportation Research Board, 2016
Travel 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.

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.
