Project Summary:

The Minnesota Traffic Observatory at the University of Minnesota, with the assistance of MnDOT, the has studied and experimented with infrastructure-based queue warning (Q-WARN) systems. A permanent field lab has been established at the high-crash area of westbound I-94 in Minneapolis, Minnesota, capturing detailed data on hundreds of crashes. This area experiences upwards of 100 crashes annually, the majority of them rear-end crashes due to failure to stop or too little headway. This research aims to capitalize on the already extensive instrumentation available at the I-94 Field Lab to develop a connected-vehicle (CV) testbed specifically for the implementation and testing of speed harmonization (SPD-HARM) and Q-WARN systems.

An infrastructure-based Q-WARN system has been implemented since April 2016 and evaluated over the space of three months in summer and fall of 2016. This project expanded the available instrumentation deployed to the I-94 site to include high-resolution radar that provides wide area vehicle trajectories at a 20Hz update interval. The system covers a 1-mile section of the test site, including the location where 90 percent of the crashes take place. The research team is proceeding with the demonstration of the INFLO SPD-HARM and Q-WARN V2I solutions. In subsequent projects, the current site will be enhanced to support fully developed CV safety systems as well as the research and evaluation of the underlying human factors of such systems. The final product envisioned will be a fully functional CV testbed uniquely situated to attract freeway safety-oriented vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) safety application development, implementation, and evaluation projects.
