WG1 work scope and work

method

Current work scope• WG1 focus on the applications and facilities layer

• WG1 set up work items based on Minimum Set of Standards defined for EC mandate 453 • Most of WIs are already started

• WG1 collaborates with other WGs for harmonization• WG2 architecture

• WG3 networking and transport

• WG5 security• WG5 security

• WG1 works closely with industrial organization Car 2 Car Communication Consortium

• WG1 exchanges information with Field Operational Test and R&D projects

• WG1 works on international harmonization

Work methods:• Regular WG meetings

• Ad hoc work meetings

• Joint meetings with other WGs

• Email discussions

• Special Task Force (STF)

Main achievements

TR 102 638: Basic set of applications• A set of applications that scope our current specification work

• A set of applications that are considered deployable at first step after standardization completion

• Safety, traffic efficiency and other applications are included in the BSA

TS 102 637 sets:• TS 102 637 – 1: BSA functional requirements• TS 102 637 – 1: BSA functional requirements

• Functional analysis of all use cases belonging to the BSA

• TS 102 637 – 2: Cooperative Awareness Basic Service• A heartbeat message that is sent periodically by vehicles and road side

• TS 102 637 – 3: Decentralized Environmental Notification Basic Service• An event driven message that announces the detected road hazard

• TS 102 637 – 4: BSA operational requirements (stable draft)

Test specifications • CAM, DENM specifications (collaboration with STF experts)

Ongoing work - applications 1/2

WG1 has initiated the work since October 2010• The WI scope is defined based on Minimum Set of Applications and

agreement of work split between ETSI and CEN

• All applications are from BSA

Three WIs on safety applications (V2V based)• TS 101 539 – 1: Co-operative Awareness application

• Cooperative awareness of the driving environment • Cooperative awareness of the driving environment

• No collision risk

• TS 101 539 – 2: Intersection Collision Risk Warning• Detection of collision risk with detection means and/or from received CAM/DENM

• Triggering of intersection collision risk warning message DENM

• TS 101 539 – 3: Longitudinal Collision Risk Warning • Detection of collision risk by vehicles or by a third part (e.g. from road side)

• Triggering of longitudinal collision risk warning message DENM

One WI on electric vehicle Points of Interest application • TS: Electric Vehicle Charging Spot Notification Specification

Close collaboration is set up

between ESTI TC ITS WG1 and ISO

TC 204 WG14 to harmonize the

application specifications !

Ongoing work – facilities

TS 102 894 : Facilities layer architecture (stable draft)• To define the overall functional architecture of the facilities

• To identify the main components of the facilities layer

TR 102 863 : Local dynamic Map (stable draft ongoing STF)• To identify the standard needs for the LDM

TS: Service announcement • To announce the available services

• To announce the communication profile to be used to access to the service• To announce the communication profile to be used to access to the service

• Close collaboration with WG2

TS: Communication management • To define the communication profile

• To define the policies to select the communication profile for communication

• Close collaboration with WG2

TS: position and time• Specifications of position and time information used in messages

• Data quality based on application requirements

Collaborations and harmonisation

1/2

Close collaboration with Car to car

communication consortium C2CCC

• Contributions of technical specifications from

C2CCC APP WGC2CCC APP WG

• Common agreement on standard needs

• Information exchange with C2CC RM WG

Liaisons with Field Operational Test (FoT)

projects

• FoTs contribute to the ETSI specification work

• WG1 provides basic specifications to FoT

• FoTs provide feedbacks and changes requests to Footer text (edit in View : Header and Footer)10

International harmonisation 2/2

WG1 contributes to the discussions of the

international harmonization in the task force

Application specificationsApplication specifications

• Close collaborations with ISO TC 204 WG14

International harmonization of message sets

• Harmonization needs and work method are under

discussions

• Harmonized data element definition

• Harmonized message general structure

• Messages content may vary depending on needs of Footer text (edit in View : Header and Footer)11

Future steps

Continuation of ongoing work

Launch of new work

• Release 2 of CAM, DENM specifications based on

FoT feedbacksFoT feedbacks

• Validation test of CAM/DENM (STF) and other test

specifications

• Common data container for messages (probably

needs international harmonization)

• Facilities layer congestion control

Collaboration with CEN

• New messages sent from infrastructure to Footer text (edit in View : Header and Footer)12
