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 now. The U.S. Department of Transportation (USDOT) is now actively promoting Speed Harmonization (SPD-HARM) and Queue Warning (Q-WARN) as the first two most implementable V2I technologies and has released a request for information regarding the establishment of Connected Vehicle (CV) Testbeds around the country. Separately, since 2003, with the assistance of the Minnesota DOT (MnDOT), the Minnesota Traffic Observatory (MTO) at the University of Minnesota (UofMN) has studied and experimented with infrastructure based Q-WARN systems. A permanent field lab has been established at the high crash area of I-94 westbound in Minneapolis, MN and is capturing detailed data on hundreds of crashes. This area experiences upwards to 100 crashes a year, the majority of them rear-end due to failure to stop or too small of headway. Capitalizing on the extensive instrumentation available at the I-94 Field Lab, a CV Testbed was developed specifically for the implementation and testing of SPD-HARM and Q-WARN systems. The project followed a phased approach where first an infrastructure based Q-WARN system was implemented and expanded to a V2I SPD-HARM and Q-WARN demonstration. The site was 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 is a fully functional CV Testbed uniquely situated to attract freeway safety oriented V2I and V2V safety application development, implementation, and evaluation projects.
