Queueing in Traffic Flows
ثبت نشده
چکیده
This project studies the effects of vehicle routing on pollution levels. We aim to develop queueing theory based mathematical models to analyse highway traffic flows and focus on focus on the capacity drop and shockwaves. Then we intend to use emission models and plume model to predict air pollution in a wider region. These predictions will be tested using remote sensing data and data from measurement stations. Finally, we aim for traffic steering methods to (re)-direct road traffic to avoid pollution.

Empirical validation of a queueing approach to uninterrupted traffic flows
In this paper, the use of queueing theory for modeling uninterrupted traffic flows is evaluated. Empirical data on speeds and flows are used to evaluate speeds generated by the different queueing models. Using the Theil inequality coefficient as evaluation criterion, the speeds generated by the queueing models are compared to the empirical speeds. Queueing models that best fit the observed spee...
متن کاملReduced-Load Equivalence and Induced Burstiness in GPS Queues with Long-Tailed Traffic Flows
We analyze the queueing behavior of long-tailed traffic flows under the Generalized Processor Sharing (GPS) discipline. We show a sharp dichotomy in qualitative behavior, depending on the relative values of the weight parameters. For certain weight combinations, an individual flow with long-tailed traffic characteristics is effectively served at a constant rate. The effective service rate may b...

A router in today’s Internet has to satisfy two important properties in order to efficiently provide the Quality of Service (QoS) requested by the users. It should be fair among flows and also have low operational complexity. T...

متن کاملOn How to Provision Virtual Circuits for Network-Redirected Large-Sized, High-Rate Flows
To reduce the impact of large-sized, high-rate (α) transfers on real-time flows, a Hybrid Network Traffic Engineering System (HNTES) was proposed in earlier work. HNTES is an intra-domain solution that enables the automatic identification of α flows at a provider network’s ingress routers, and redirects these flows to traffic-engineered QoS-controlled virtual circuits. The purpose of this work ...
