Project Summary

Safety and traffic operations concepts based on vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication have been in development for some time. The U.S. Department of Transportation is now actively promoting speed harmonization (SPD-HARM) and queue warning (Q-WARN) as the first two most-implementable V2I technologies and has a request for proposals regarding the establishment of connected vehicle (CV) pilots around the country. With the assistance of MnDOT, the Minnesota Traffic Observatory at the University of Minnesota has studied and experimented with infrastructure-based Q-WARN systems. A permanent field lab has been established at the high-crash area of westbound I-94 in Minneapolis, Minn., 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 CV testbed specifically for the implementation and testing of SPD-HARM and Q-WARN systems. The project is following a phased approach, where first an infrastructure-based Q-WARN system will be implemented and expanded to a V2I SPD-HARM and Q-WARN demonstration. 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 of this project will be a fully functional CV testbed uniquely situated to attract freeway safety-oriented V2I and V2V safety application development, implementation, and evaluation projects.
