Development and Tech Transfer of an Integrated Robust Traffic State and Parameter Estimation and Adaptive Ramp Metering Control System

The research team proposes a comprehensive effort to resolve several common issues associated with prevailing traffic state estimation algorithms based on discrete-time first-order kinematic wave traffic flow models and to develop an adaptive ramp metering control system based on the improved traffic estimation scheme. The effort is composed of traffic flow model modifications, development of a multi-modal adaptive filtering approach to traffic state and parameter estimation scheme, development of measures to integrate emerging traffic data with conventional fixed-point measurements, development of a measure for on-line estimation of capacity-drop-proportion, development of an adaptive discrete switching feedback controller for ramp metering, and implementations of the proposed schemes in both macroscopic numerical simulation and microscopic traffic simulation platform.
