A novel approach for vehicle travel time distribution: copula-based dependent discrete convolution
Transportation letters, 2021Travel time reliability is considered as one of the key indicators for the performance of transportation systems. The majority of studies concerning estimating arterial travel time distribution commonly assume that the path travel time follows a certain ...

Estimation of Link Travel Time Distribution With Limited Traffic Detectors
IEEE transactions on intelligent transportation systems (Print), 2020Motivated by the network tomography, in this paper, we present a novel methodology to estimate link travel time distributions (TTDs) using end-to-end (E2E) measurements detected by the limited traffic detectors at or near the road intersections. As it is

Estimation of urban arterial travel time distribution considering link correlations
Transportmetrica A: Transport Science, 2020This study proposes a pair-copula construction approach to estimate the probability distribution of urban arterial travel times from link travel time distributions (TTDs).

Synthesizing Route Travel Time Distributions from Segment Travel Time Distributions
Transportation Research Record: Journal of the Transportation Research Board, 2013This 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 important aspect of the quality of a public transport service is its reliability, which is defined as the invariability of the service attributes. In order to measure the reliability during the service planning phase, a key piece of information is the

Consequences of mixing assumptions for time‐variable travel time distributions
Hydrological Processes, 2014AbstractThe current generation of catchment travel time distribution (TTD) research, integrating nearly three decades of work since publication of Water's Journey from Rain to Stream, seeks to represent the full distribution in catchment travel times and its temporal variability. Here, we compare conceptualizations of increasing complexity with regards

Travel time reliability quantifies variability in travel times and has become a critical aspect for evaluating transportation network performance. The empirical travel time cumulative distribution function (CDF) has been used as a tool to preserve inherent information on the variability and distribution of travel times.

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 urban route travel time distribution using Markov chains and pair-copula construction
Transportmetrica B: Transport Dynamics, 2019Route 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).
