A Dynamical Framework for Integrated Corridor Management

Project Number

14-09

Project Summary

In this application for the Research Initiation Award, we propose to develop dynamic traffic signal control and ramp metering strategies for Integrated corridor Management (ICM) with provable performance guarantees. There are several novel contributions of our proposed approach. First, we perform control synthesis within a dynamical framework that allows dynamic route choice and dynamic mode choice by drivers, and as such is different than typical approaches that use very specific models. Second, we make connections between our dynamical framework and compartmental dynamical systems in order to leverage powerful stability analysis tools for control design. Third, we propose to extend metrics for system efficiency beyond total travel time, to also include resilience, and relate these metrics to network parameters. Finally, we propose to use stability analysis tools to design traffic signal and ramp metering control, that require minimal information about dynamic driver decisions, and hence are well-suited for incidence response scenarios in the context of ICM. Our proposed approach relies on a combination of tools from traffic engineering, dynamical systems and network flows. We will supplement our analysis and algorithm development with case studies relevant to the Los Angeles area, using commercial transportation software.
