• 車聯網V2X是以應用為導向的通訊技術，從早期的Telematics使用2G/3G/4G的技術開始，2000年左右美國運輸部開始推動DSRC技術以及相關道路安全應用，直到2016年3gpp於Release 14開始訂定C-V2X車聯網技術標準，V2X技術以及相關的智慧交通與自駕車議題在這個過程中受到大眾愈來愈多的關注。

• 簡報中將介紹國內DSRC以及C-V2X通訊技術的開發現況。同時，由於車聯網V2X是以應用為導向的通訊技術，簡報中也會介紹國內相關應用以及網路佈建的狀態和後續的規劃。

MOTC - Smart Transportation System Development Project Examples (2017)

• Project name: Vehicle & Roadside Collaborative Design and Implementation

• Application: Intersection Anti-collision Warning Install OBU on the light rail trains Use DSRC to transmit messages for detecting and

identifying the attributes, static and dynamic information of vehicles, light rail trains and infrastructure on the road

Roadside CMS provides light rail trains intersection anti-collision warning service along the line

OBU

Kaohsiung City

• Project name: Smart Intersection Warning System

• Application: Pedestrian Collision Warning Build pedestrian warning system at the

intersection Install OBU on the bus Avoid collisions between pedestrians and

vehicles

Taipei City

• Project name: Smart Intersection Safety Warning System

• Application: Intersection Anti-collision Warning Select two intersections to construct warning system to

avoid collisions between vehicles or pedestrians and vehicles.

US Mandate for Automotive Industry

• 11• NPRM since 3rd Feb 2014 (USDOT)

▪ All new passenger car must install V2V devices, i.e. DSRC▪ Most Update: Legislation process is expected to start after 2017/07

(pending now)

• ITRI’ Activities for NPRM▪ So far 18 companies have participated in V2X Industry Partner

Program▪ Technology research and development, ex: USDOT’s Research

Qualified Product List (rQPL) and PlugFest▪ Participate in international cooperation and assist manufacturers to

export. Such as CAMP, CV Pilot, PATH, C-Roads…etc

Three Scenarios in 5G URLLC is one of the three scenarios (eMBB, mMTC, URLLC) of 5G services

defined by 3gpp：Autonomous car and smart traffic are important application of URLLC。eV2X is one of 5G key application

• Lower Latency• High Reliability• High Mobility

URLLC for Vehicle Applications

R14 : C-V2X is included in the 3GPP standard. Two modes : (1) V2I & V2N (2) V2V V2I & V2N : use LTE Broadcasting (eMBMS) technology ( ~100 ms) V2V : use PC5 technology ( ~100 ms)

R15 : develop Localized eMBMS Function and push eMBMS components toMobile Edge for lower transmission latency.

R16/R17 : develop 5G C-V2X standard (~10 ms) and Advanced V2X Services


Broadcasting based C-V2X toward 5GV2I & V2N

R14/R15：push C-V2X functions from core network to Mobile Edge Computing (MEC) Separate control/user components. Finish Localized eMBMS Function which will run on a virtualization

platform through virtualization and micro-services technology. MCE component for multi-base station radio resource management. Optimize the network latency for

V2X services. Support both MBSFN and SC-PTM broadcasting modes. The Deployment & Management of V2X services and applications

R16/R17： 3gpp will define Advanced V2X Service and C-V2X Air interface that complies with 5G-NR

DSRC vs C-V2X in US V2V NPRM– DSRC mainly adopted in US (IEEE-1609 and 802.11p)、Japan (ARIB

700 MHz) and Europe (ETSI ITS-G5)，• Architecture and Application are V2V (5.9 GHz – Road Safety)，• Supported by C-ITS operators and car vendors，ex: Toyota & VW。

– C-V2X (3gpp) mainly adopted in China and Europe，• Architecture and application are V2I (Cloud)、V2V (Licensed band – New

Business Model) and V2V (5.9 GHz – Road Safety) ，• Supported by Mobile Operators and car vendors，ex: Audi & BMW

Supporters of Both Standards exist ITRI has prepared solutions for both technologies

ICL-U has involved in both DSRC and C-V2X– (EU)C-ITS operators have proposed the concept of Hybrid

Communication for future ITS services
