The invention utilizes the layering modulation technology for communication between vehicle and infrastructure (V2I) (the simultaneous transmission of the high end information and low end information) to make all the vehicles decode the high end information having high important degree. When the receiving environment is unsatisfactory due to the remote communication and the existence of a barrier, the vehicles that only decode the high end information will require other vehicles having good receiving environment to transmit the low end information. In addition, with the multi hop relay technology and other communication technologies (V2V) between vehicles, the vehicles that decode both high end information and low end information will be made to transmit low end information only, thus to raise the overall receiving performance.
