Connected Vehicles Project

Connected Vehicles systems use 5.9 GHz Dedicated Short Range Communications (DSRC) to enable vehicle active safety systems which could help drivers avoid crashes. The United States Department of Transportation (USDOT) has partnered with the Crash Avoidance Metrics Partnership (CAMP) Vehicle Safety Communications 3 (VSC3) Consortium to research, develop and test the technologies that form the framework for these systems. The CAMP VSC3 Consortium consists of the Ford Motor Company, General Motors LLC., Honda R&D Americas, Inc., Hyundai-Kia America Technical Center, Inc., Mercedes-Benz Research and Development North America, Inc., Nissan Technical Center North America, Inc., Toyota Motor Engineering & Manufacturing North America, Inc. and Volkswagen Group of America.

Summary of the project:

• Designed and executed large-scale vehicular field experiments in California and Michigan with several hundreds of vehicles equipped with DSRC transceivers.
• Designed, implemented and calibrated a scalable network simulator.
• Redesigned, calibrated, and implemented several network simulator’s propagation loss models for DSRC communication. Validated the calibration by state-of-the-art cross-validation techniques, using field experiment data.
• Enhanced ns-3 simulator to perceive vehicular environment through recognizing vehicles as a 3D object rather than an antenna coordination, and implemented a propagation loss model for using such enhancements to improve link-level simulation accuracy.
• Implemented and maintained three different congestion control algorithms in ns-3 simulator based on available standards and design proposals.
• Executed simulations for several dense environments and scenarios, and compared performance via different metrics at different stack layers for such cases.
