•Preliminary observations from the 200 vehicle
test scenarios:
•The channel congestion level was highest for
the Baseline 10 Hz configuration
but was not to the point of being fully saturated
•For all configurations and scenarios, there
was no evidence of significant degradation of the communication performance that would
seem to result in
degradation of the vehicle safety applications for 200 vehicles
•Algorithm X and Algorithm Y show promising
communication performance that may result in good
performance of the vehicle safety applications for 200 vehicles while reducing the channel
utilization to lower values in comparison to the baseline 10 Hz configuration
•Next Steps – Finalize V2V safety
communication technique(s) that will support large-scale deployment level of vehicles
while preserving
the performance of V2V safety applications (Phase II)
•Calibration of communication simulation
environments
•Algorithm refinement and, if necessary,
development of alternate approaches
•Field testing
•Incorporate recommendations into standards
