Bringing Order to Chaos: The Growing Role of Proactive Traffic Management Solutions
Increasingly, proactive traffic management strategies can be deployed on freeways and arterials with the aim of improving safety while reducing congestion and emissions. The toolbox of applications usually includes ramp metering, variable speed limit systems, advanced traffic signal control, traffic information, incident management, multimodal corridor management, and high occupancy/toll managed lanes. This presentation will present an overview of proactive traffic management solutions that fit particular problems. A case study of a worldwide analysis of variable speed limit (VSL) systems will be presented. VSL is usually applied to harmonize traffic flow during congestion, weather and construction events. A summary of applications and algorithms uncovered during an international survey will be described, along with detailed analyses from several corridors in the U.S. and in Europe. Example evaluation results will be shown, including impacts on safety, travel time, travel time reliability and driver compliance. These analyses will illuminate new rollouts of proactive traffic management solutions. By providing system performance feedback derived from high resolution empirical data, we can shed light on options for improving system performance. Download Handout
