基于专用短程通信的港口车路协同

A Study on DSRC Application to V2X in Ports

为探究基于专用短程通信(Dedicated Short Range Communication,DSRC)的港口运输车路协同的应用前景,对DSRC技术及其典型应用场景进行介绍,分析该技术的优缺点。阐述基于DSRC技术的港口车路协同的技术架构和应用场景,通过对比DSRC与蜂窝车联网技术,指出DSRC面临的挑战并提出应对建议。分析认为目前基于被动式DSRC的车路协同技术在港口车辆身份认证方面具有一定的应用,但不能完全满足自动驾驶车辆与智能道路间实时信息交互的需求;我国已在DSRC标准层面针对自动驾驶需求明确实时信息交互方式,因此在DSRC技术层面还会不断演进,以满足更广泛的车路协同需求。

The prospect of DSRC(Dedicated Short Range Communication)application in port is investigated.The development of DSRC is reviewed,analyzing the pros and cons of DSRC.Scenarios of DSRC application in ETC(Electronic Toll Collection)and port V2X(Vehicle-to-everything)are investigated,comparing DSRC to cellular scheme.The weakness of DSRC in V2X is discussed.It concludes that passive DSRC can be used for vehicle identity verification,but cannot yet fully satisfy the needs of real-time information interchange between self-driving vehicles and intelligent roadside infrastructures.However,as the information interchange standardization is advancing,this problem is expected to be solved through DSRC evolution.
