The signal quality and message integrity of DSRC-based V2V applications that alert drivers of reduced visibility and dangerous road weather conditions are maintained even in foggy environments.

The results of the simulation indicated that a DSRC signal with a wavelength of 0.05 meter will persist in its integrity and quality while propagated through a foggy environment under a wide range of…
