V2X


— Objective Establish advanced connectivity technologies on VicRoads’ highest focus safety issues

— Innovation project created by Telstra - Mobile Operator in Australia

— Develop several V2X applicationse.g., In-vehicle speed warning, Right turn assist, Curve speed warning, slow/stopped vehicle

— VicRoads sponsors the project as part of the “Towards Zero” strategy

— Safety use cases demonstrated to VicRoads in February and end of May 2019 – project goes into 2020

Enabling innovationwith Telstra/Lexus V2X


Natural evolution of the Connected Vehicles

From V2N2’U’, Vehicle to Network to User

Vehicle connected to network and provides remote services for users, e.g. remote control, remote dashboard and remote diagnostics, etc.

To V2N2I Road Infrastructure to Network to Vehicle

The connected vehicles start to interact with the road Infrastructures through the network

And V2N2VVehicle to Network to Vehicle

The vehicles also talk with other vehicles through network


Use Cases – MNO/Road Traffic authority V2X


Use Case Description

Emergency Electronic Brake Light (EEBL) A vehicle has an emergency braking event. This event is relayed via the V2X Platform to other vehicles in the area, where these vehicles may display an alert if the message is relevant to the driver.

V2N2V

In-vehicle Speed Warning A vehicle is sent the speed limit relevant to its current position and trajectory, as specified by VicRoads.

V2N2I

Right-Turn Warning Assist A vehicle is sent information relating to pedestrians at controlled intersections when making a right-hand turn.

V2N2I, V2N2I

Curve and advisory-Speed Warning Even advisory speed limit if relevant V2N2IRed Light Violator Warning A vehicle is not slowing when approaching a red light at a

controlled intersection. This vehicle displays an alert, and the information is relayed to other vehicles in the area which also display an alert if the message is relevant (for instance, if they predict a collision).

V2N2I, V2N2V

Slow Vehicle Warning (Forward Collision Warning)

A vehicle is slow or otherwise impaired. This is relayed to other vehicles in the area, which display an alert if the message is relevant to the driver.

— 10-100x cost saving for public sector (compared to deploying Roadside Units)

— Fastest service penetration by leveraging vehicular cellular connectivity

— Low, controlled latency with 4G, further improved with 5G

— Flexible deployment and interoperability— Future/backwards compatibility— Road infrastructure as part of the larger IoT

Network Latency, example


V2X latency on Uu— Deterministic scheduling for V2X users— Idle-Mode and DRX modifications— Minimum rate for V2X users to sustain

CAMs/DENMs— Partial priority over general internet users,

(lower than emergency services)

E2E QoS across entire Telstra Network— 3GPP QCI 79(Non GBR V2X)— Same Quality of Service (QoS) system that

exists for Voice over LTE (VoLTE)

— Includes the messages types:— Cooperative Awareness Message (CAM), a standardized

message from ETSI for exchanging the cooperative awareness within road traffic

— Decentralized Environmental Notification Message (DENM), a standardized message from ETSI contains information related to a road hazard or an abnormal traffic conditions, such as its type and its position.

— The Signal Phase and Timing (SPAT) message is used to convey the current status of one or more signalized intersections.

— The MAP message is used to convey many types of geographic road information. At the current time its primary use is to convey one or more intersection lane geometry maps within a single message

— In-vehicle information (IVI) data structures are required by different ITS services for transmitted information includes contextual speed, road works warnings, vehicle restrictions, lane restrictions, road hazard warning, location-based services, re-routing,

— CVC-V2X is a could application which connects and receives the messages from both connected vehicles and road infra systems, process, correlate and delivery messages

— The messages have very big volume and high frequency, and which should be handled with very short latency

— CVC-V2X includes the following key components/capabilities:

— Interchange, connect and distribute the transport information from the various road infra systems, e.g. traffic controller, pedestrian sensor, etc.

— Vehicle Communication, securely connect and communicate the vehicles with the standard protocols, e.g. IVI, CAM, DENM, MAP and SPaT, etc.

— Processing, the streaming processing engine to process and deliver all the messages to support different use case

— Geo Grid, process, store and query the key transport information base on geometry grid.

— Geofencing, dynamically mange the geofences and calculate the different events in real-time

— A geo-fence is digital representation of a geographical area where certain rules apply

— Each vehicle reports GPS coordinates, speed and direction frequently (10 Hz)

— Algorithms detects when a vehicle is within, enters or exits a geofence

— In this project, geo-fences are created dynamically in certain dangerous traffic situations (but static/predefined in some use cases)
