This paper develops an analytical framework for ramp metering, under which various ramp control strategies can be viewed as ramifications of the same most-efficient control logic with different threshold values, control methods, and equity considerations. The most-efficient control logic only meters the entrance ramps nearest critical freeway mainline sections so as to eliminate freeway interna...

The purpose of this paper is to review the essential definitions, roles and characteristics of communication on metering system. We discuss measurement, data acquisition and metrological control of a signal sensor from dynamic metering system. After that, we present instruments of sensor communication with more detailed discussions to the reference standards and the important fundamental parame...

Many factors influence the quality of turbine meter flow measurement. Recognizing these factors allows a user to optimize the flow measurement performance of a turbine metering system. In order to ensure that turbine meters in the field are operating at their best, turbine metering stations must be properly designed, calibrated, installed, and maintained on a regular basis. This paper explains ...

New procedures and technologies of Air Traffic Control (ATC) under development in Next Generation Air Transportation System (NextGen) will change controllers' tasks, roles, and responsibilities. However, cognitive complexity will remain one of the limiting factors in future system's capacity and none of existing complexity metrics can be directly extended to evaluate cognitive complexity under ...

A metering scheme is a method by which an audit agency is able to measure the interaction between clients and servers on the web during a certain number of time frames. Naor and Pinkas 7] considered metering schemes in which any server is able to construct a proof to be sent to the audit agency if and only if it has been visited by at least a number, say h, of clients in a given time frame. In ...

This paper discusses the application of coalitional model predictive control (MPC) to freeways traffic networks, where goal is reducing time spent by drivers through a dynamic setting variable speed limits (VSL) and ramp metering. The prediction METANET used represent flows evolution. system behavior objective function lead non-convex non-linear optimization problem, which can only be solved in...

Climate change, awareness of energy efficiency, new trends in electricity markets, the obsolescence of the actual electricity model, and the gradual conversion of consumers to prosumer profiles are the main agents of progressive change in electricity systems towards the Smart Grid paradigm. The introduction of multiple distributed generation and storage resources, with a strong involvement of r...

In order to decide on advertisement fees for web servers, Naor and Pinkas 7] introduced metering schemes. They proposed metering schemes in which any server is able to construct a proof to be sent to an audit agency if and only if it has been visited by at least a certain number, say h, of clients. Afterwards, the authors of 3] generalized the idea of Naor and Pinkas and proposed metering schem...

Currently, Advanced Metering Infrastructure (AMI) systems have equipped the low voltage section with a communication system that is being used mainly for metering purposes, but it can be further employed for additional applications related to the Smart Grid (SG) concept. This paper explores the potential applications beyond metering of the available channel in a Power Line Communication-based A...
