Ramp Metering Impact Study with Potential Regional Deployment within the Dallas-Fort Worth Ozone Nonattainment Area

Single Lane Ramp Meter Microscopic Simulation.

Project Summary

The Researchers will investigate deploying ramp metering in the Dallas-Fort Worth (DFW) Metroplex to alleviate freeway traffic congestion and improve air quality. The Researchers will begin by identifying freeway corridors and ramp locations which meet necessary design and traffic conditions criteria for ramp metering and candidate ramp metering strategies. Then, the Researchers will conduct detailed analysis of case studies – candidate ramp metering strategies in selected corridors – using a combination of regional-level dynamic traffic assignment and simulation modeling, corridor-level microscopic simulation, and corridor (project) level emissions modeling. The Researchers will use the results from these models to identify where and to which extent ramp metering should be deployed in the selected corridors.
