Feedback Ramp Metering in Intelligent Transportation Systems is the first book on the topic of using feedback control (also called real-time traffic control or adaptive control by some traffic engineers) in ramp metering. It provides traffic theory fundamentals and then the design of feedback controllers for isolated and coordinated ramp metering by: This paper represents a novel modeling technique of PV module with a fuzzy logic based MPPT algorithm and boost converter in Simulink environment.

Nature has always been a great source of inspiration to all mankind. Genetic Algorithms (GAs) are search-based algorithms based on the concepts of natural. Project Summary: This project involved a detailed review of coordinated metering algorithms currently operating in the United States and a simulation analysis to examine the performance of three algorithms that represent each coordination approach; the Denver incremental coordination algorithm, the Seattle fuzzy metering algorithm, and the Minnesota explicit section-wide coordination algorithm. A ramp meter, ramp signal, or metering light is a device, usually a basic traffic light or a two-section signal light (red and green only, no yellow) together with a signal controller, that regulates the flow of traffic entering freeways according to current traffic conditions. Ramp meters are used at freeway on-ramps to manage the rate of automobiles entering the freeway. Fuzzy logic is a form of many-valued logic in which the truth values of variables may be any real number between 0 and 1 both inclusive. It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false. By contrast, in Boolean logic, the truth values of variables may only be the integer values 0 or 1.

This thesis presents an evaluation study of two ramp metering algorithms. The study uses microscopic traffic simulation to evaluate the performance of ramp control algorithms with respect to key input parameters for the Central Artery/Tunnel (CA/T) network in Boston. Expert systems, fuzzy logic systems, neural networks and genetic algorithms are major AI technologies which have made an impact on the petroleum industry. Presently, these technologies are at different stages more» of maturity with expert systems being the most mature and genetic algorithms the least. Neural networks are basically pattern recognition engines. They "learn" from mistakes as you train them. They are not adaptive or especially non-linear. The PID control can be adapted with continuous self-tuning, if you expend the effort. The most common control algorithm for your type of application in mechanical systems is fuzzy logic.

Fuzzy logic ramp metering algorithms will address the needs of Seattle's freeway system and overcome the limitations of the existing ramp metering algorithm. The design of the fuzzy logic controller (FLC) reduced the sensitivity to sensor data, which frequently contains errors or noise.

The rule base effectively balanced the two opposing needs: to alleviate mainline congestion by restricting the metering rate, and to disperse the ramp queue by increasing the metering rate. Today’s cooperative ramp metering algorithms adjust the metering rate for every on-ramp according to the overall traffic state on the highway and can establish additional cooperation with other traffic control subsystems.
