Driverless car has a promising future, but has limited detection coverage. DSRC has a much wider range (~1000 meters) and robust characteristics in radio communication and strong performance during adverse weather conditions. By combining driverless car and DSRC system, the car can receive information out of its detection range. DSRC system could send urgent information which is on the car’s route to the driverless car. Then by specific computer programming, driverless car would take action beforehand. Besides, with the network of DSRC systems, the information of road condition could propagate even further away.
