I-94 Connected Vehicles Testbed Operations and Maintenance
- John Hourdos, Director, MN Traffic Observatory, Civil, Environmental and Geo-Engineering
The Roadway Safety Institute (RSI) funded the creation of the I-94 Connected Vehicles Testbed as an addition to the existing I-94 Field Laboratory of the Minnesota Traffic Observatory. The Testbed upgrade introduced, in the existing surveillance and data collection infrastructure, the ability to collect detailed vehicle trajectories from seven 24GHz radar covering the I-94 WB high crash frequency area in Downtown Minneapolis, MN. The Radar infrastructure has been complimented by a backoffice system that collects the vehicle trajectories in real-time, stores them, and makes them available to any external applications through a provided Application User Interface. Developing the CV Testbed to provide such information from a busy and difficult to access freeway was challenging and required many customized hardware and software solutions. Both the continuous operation of the I-94 Field Lab and now the CV Testbed involves many layers of technology that require constant monitoring and frequent maintenance. While most of such expenses have been covered by RSI and Minnesota Department of Transportation (MnDOT) projects, there are costs that are ongoing and periods where there are no projects utilizing the Testbed infrastructure. The project covers the effort securing the uninterrupted operation of the Testbed and performs changes and upgrades in view of the large reconstruction project MnDOT started on April 2018, which required the relocation of two of the seven radar stations.
