Road congestion is a common problem worldwide. In developed countries, automated congestion detection techniques are used in road travel assisting applications. But these techniques are mostly inapplicable in developing regions due to high cost and their assumptions of orderly traffic. We present two techniques for effective congestion detection in chaotic traffic of developing regions. Our fir...

Congestion is one of the main issues in data envelopment analyses which have particular importance. Recently researches about congestion, whether in economic articles or in Operations Research articles in had grown increasingly. Congestion is a wasteful stage of the production process where outputs are reduced due to excessive amount of inputs. In economics, congestion is very important because...

The electricity demand is continuously increasing, so a most efficient use of the current power system's capacity desired. Flexible AC Transmission Systems (FACTSs), recently developed transmission technology, are widely used to boost transfer ability long-distance line networks and enhance consistency systems. FACTS devices can lead reduced flows on heavily loaded lines, targeted bus voltage l...

High-Efficient traffic system is very important for economy and society of c ities. Previous studies on the traffic comparison mostly took a city as a whole, but ig nored the differences among areas inside the city. But in fact, the traffic congestion in different areas with a city is mostly different. Taking typical megacities like Beijing, London, New York, and Tokyo as objects, this paper ma...

Nodal prices, congestion revenues, transmission capacity rights, and compensation for wire ownership are key concepts used to formulate claims about proposals to organize competitive and open transmission access. Underlying those claims are implicit assertions (folk theorems) concerning the regulation of transmission access, the determination of power ows, properties of economic dispatch, and t...

the new competitive environment changes the paradigm of power system operation. in the transmission area, open access process provides fair accessibility for all market participants. congestion management is one of the most important side effects of this new process. this paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the networ...

Understanding the distribution of congestion in the Internet is a long-standing problem. Using data from the SamKnows US broadband access network measurement study, commissioned by the FCC, we explore patterns of congestion distribution in DSL and cable Internet service provider (ISP) networks. Using correlation-based analysis we estimate prevalence of congestion in the periphery versus the cor...

The objective of this paper is to present experimental results for testing the performance of different auction mechanisms related to the introduction of competitive markets for the generation of electricity. The research is based on the concept of smart markets introduced by Vernon Smith and a simulation model (PowerWeb) of a realistic bulk power system. There are unique physical aspects assoc...
