Development of Freeway Management and Operational Strategies with IRIS-In-LOOP Simulation
Principal Investigator:
Eil Kwon, Director, NATSRL, UMD-Civil Engineering
Project Summary:
Efficient and robust traffic-control systems are critical to effective freeway management. The current freeway network in the Twin Cites is managed with the Intelligent Road Information System (IRIS), a computerized operating system developed by Mn/DOT to control field devices such as ramp meters, variable message signs, and loop detectors. Our project aims to improve this system by integrating into it a microscopic traffic simulator. The resulting system, the IRIS-In-Loop simulation system (ILSS) would allow us to emulate and refine various strategies before implementing them in the field. Our first application of ILSS will involve an alternative ramp-metering strategy, which we will develop in this project and evaluate with ILSS. We will also use ILSS to estimate traffic conditions in various freeway corridors; these estimates will assist Mn/DOT in its decision making process.
