Part I: Modeling, Estimation, and RampMetering Control of Freeway Traffic Themain objective of Part I is to develop improved algorithms for freeway on-ramp metering control. Toward this end, two macroscopic traffic models are first introduced and analyzed. The first is a modification of the cell transmission model (CTM) developed by Daganzo. This modified CTM uses cell vehicle densities as its ...

Abstract At present, the current positive and negative sequence extraction methods are all based on high-performance analog-to-digital converters need microprocessors. Or measurement circuit is constructed using an analog operational amplifier, phase shifting method used to achieve purpose. The above be implemented by chips with high computing power. They even build additional circuit, which ma...

Aiming to solve the problems of poor uniformity seed flow discharge and serious damage traditional straight grooved wheels improve performance air-assisted maize high-speed precision metering devices, a staggering symmetrical spiral feeding wheel with seeds was designed. To explore influence groove inclination angle length staggered feed on discharge, l ρ were used as experimental factors, vari...

Abstract Internet of Things (IoT) has recently become one the fast‐growing technologies in world. Integrating existing systems with smart grids still represents a significant challenge arising from massive cost upgrading infrastructure. This paper provides an IoT infrastructure solution based on newly designed low‐cost microcontroller‐based remote terminal unit (RTU) to integrate new, old, and ...

This paper treats the problem of controlling large freeway systems through ramp metering to enhance their efficiency. Following a rigorous discretization methodology, an extension of the CTM model to inhomogeneous freeways with on and off ramps is proposed. Based on passivity theory and the piecewise affine formulation of this model, an LMI formulation is developed to design non-local feedback ...
