Project: #274 Cost-Effective Designs of Smart City Technologies for Vehicular Communications Progress Report - Reporting Period Ending: Sept. 30, 2019 Principal Investigator: Jon Peha Status: Active Start Date: July 1, 2019 End Date: June 30, 2020 Research Type: Advanced Grant Type: Research Grant Program: FAST Act - Mobility National (2016 - 2022) Grant Cycle: 2019 Mobility21 UTC Progress Report (Last Updated: Sept. 28, 2019, 5:38 a.m.) % Project Completed to Date: 10 % Grant Award Expended: 0 % Match Expended & Document: 10 USDOT Requirements Accomplishments Our goal is to help city leaders, federal, state and local transportation authorities, the Federal Communications Commission, automakers, and ISPs make good decisions about V2X technology and policy. We have been developing simulation software that will allow us to compare two kinds of technology, DSRC and C-V2X, based on how well they can support certain roadway safety applications. In particular, we are currently focusing on an application that urges a driver to brake when it is approaching the car immediately in front of it too rapidly, creating a risk of collision. In the coming period, we will continue to work on simulating these two protocols, and observing impact on this critical application, to better understand and quantitatively assess whether one technology has significant advantages over the other. We anticipate important results in the months to come. We made great progress on disseminating results from this project, including a paper published in a prestigious IEEE journal, a presentation at an international conference, and another presentation invited at an upcoming international conference. This project provided opportunities for a Carnegie Mellon Ph.D. student turned Post Doc, from an underrepresented minority, to build his expertise. Impacts The Chairman of the Federal Communications Commission (FCC) publicly indicated this summer that the FCC will be taking a fresh look at spectrum allocations of intelligent transportation systems. That proceeding has the potential to substantially reshape V2X technology in the U.S., and in doing so it will change the strategy of every municipality and car-maker in the county. The results of this research project will be considered in that FCC proceeding. Some of these results, which quantify the impact of spectrum sharing between intelligent transportation systems and unlicensed devices, have already been presented to the FCC. More results relevant to the FCC were published this month, and still more are in the pipeline. Other None Outcomes New Partners None Issues The project has been delayed a bit. The start date was officially changed to September. One of the researchers on this project has accepted a position outside of CMU because Traffic 21 funds could not fund him for the entire year. However, we are still working, and still making progress towards the stated goals.
