Asymptotically optimal load balancing in large-scale heterogeneous systems with multiple dispatchers [PDF]

open access: yes, 2020
We consider the load balancing problem in large-scale heterogeneous systems with multiple dispatchers. We introduce a general framework called Local-Estimation-Driven (LED).

Estimating Dynamic Traffic Matrices by using Viable Routing Changes [PDF]

open access: yes, 2007
: In this paper we propose a new approach for dealing with the ill-posed nature of traffic matrix estimation. We present three solution enhancers: an algorithm for deliberately changing link weights to obtain additional information that can make the ...

Random Traffic Flow Simulation of Heavy Vehicles Based on R-Vine Copula Model and Improved Latin Hypercube Sampling Method

open access: yesSensors, 2023
The rationality of heavy vehicle models is crucial to the structural safety assessment of bridges. To establish a realistic heavy vehicle traffic flow model, this study proposes a heavy vehicle random traffic flow simulation method that fully considers ...

Energy-efficient street lighting through embedded adaptive intelligence [PDF]

open access: yes, 2013
Streetlights place a heavy demand on electricity usage, providing significant financial and environmental burdens. Consequently, initiatives to reduce energy consumption have been proposed, usually by turning off or dimming the streetlight. In this paper,

Heavy traffic analysis of roving server networks [PDF]

open access: yesStochastic Models, 2016
This paper studies the heavy-traffic (HT) behaviour of queueing networks with a single roving server. External customers arrive at the queues according to independent renewal processes and after completing service, a customer either leaves the system or is routed to another queue. This type of customer routing in queueing networks arises very naturally

The influence of heavy goods vehicle traffic on accidents on different types of Spanish interurban roads

open access: yes, 2009
This paper illustrates a methodology developed to analyze the influence of traffic conditions, i.e. volume and composition on accidents on different types of interurban roads in Spain, by applying negative binomial models.

Heavy-traffic limits for nearly deterministic queues [PDF]

open access: yesACM SIGMETRICS Performance Evaluation Review, 2010
We establish heavy-traffic limits for "nearly deterministic" queues, such as the G/D/n many-server queue. Waiting times before starting service in the G/D/n queue are equivalent to waiting times in an associated Gn/D/ 1 model, where the G
