Fluid Approximation of Point-queue Model

open access: yesProcedia, Social and Behavioral Sciences, 2014
AbstractPoint-queue model is widely used in the dynamic user equilibrium (DUE) analysis in discrete-time or continuous-time form. In this paper, a continuous time point queue is proposed. In the former studies, the negativity of the queue length of the original point-queue model is shown and some improvement has been made. Based on the observation that

A theory of multiple vehicle type dynamic marginal cost considering departure time choices

open access: yesTransport, 2010
The analysis of single vehicle type dynamic marginal cost is extended to multiple vehicle type dynamic one based on time-dependent multiple vehicle type queue analysis at a bottleneck.

MODELLING OF EXPECTED TRAFFIC SMOOTHNESS IN URBAN TRANSPORTATION SYSTEMS FOR ITS SOLUTIONS [PDF]

open access: yesArchives of Transport, 2015
In urban networks, with dense traffic flows and a high risk of the disruption (even in the form of a short queue of vehicles) the probability of occurrence of such a situation (disruption and queue) is a better measure of the probabilistic description of

Point queue models: A unified approach [PDF]

open access: yes, 2014
In transportation and other types of facilities, various queues arise when the demands of service are higher than the supplies, and many point and fluid queue models have been proposed to study such queueing systems.

Mechanized verification of a fine-grained concurrent queue from meta’s folly library

open access: yesCertified Programs and Proofs, 2022
We present the first formal specification and verification of the fine-grained concurrent multi-producer-multi-consumer queue algorithm from Meta’s C++ library Folly of core infrastructure components. The queue is highly optimized, practical, and used by

Capacity of queues via point-process channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2006
A conceptually simple proof for the capacity formula of an exponential server timing channel is provided. The proof links the timing channel to the point-process channel with instantaneous noiseless feedback. This point-process approach enables a study of timing channels that arise in multiserver queues, queues in tandem, and other simple ...
