| Abstract: |
| Vehicle-to-everything(V2X) communication technology is one of the enablers for intelligent transportation and intelligent vehicles.However,considering the problems such as unspecific technology paths and policy-making lags,it has not been deployed effectively.To clear up the existing confusion,this paper clarifies benefits and significance of V2X applications,and focuses on illustrating the characteristics and current problems of two major V2X technology solutions,dedicated short range communication(DSRC) and cellular-V2X(C-V2X).Based on a summary of the latest progress in relevant policies,laws,standards and industrialization,the future trend of V2X is analyzed to provide reference for Chinese government to formulate related policies and regulations,as well as for enterprises to define their strategic direction. |
