28/08/2020 VTT – beyond the obvious

Effectively operating and safe road network is a

critical requirement for the modern society

• EU has a vision of close to zero casualties in

traffic by 2050

The current technological transformation towards

connected and increasingly automated vehicles

can help in improving road safety and maintenance

So far, the lack of sufficient communication media

and scalable data processing solutions has

hindered the wide-scale adoption of advanced

vehicular services

• 5G is expected to bring a solution to this

Background

Overview of the Challenge Finland 5G-SAFE project


Name: Road safety enhancements enabled by 5G (5G-SAFE)

Aim: “Improving road safety, optimizing logistics and road

maintenance, and contributing to the future of autonomous

driving by delivering novel focused services to vehicles,

road users, and 3rd party organizations in real-time.”

Project consortium:• Research partners: VTT (coordinator), FMI

• Industry partners: Destia, FMI Services,

Kaltiot, SITOWISE, Unikie

• In-kind partners: Nokia, Sunit, VR Transpoint

• Advisory board: Dynniq (NL), Finnish Transport Agency,

Finnish Transport, Safety Agency (Trafi), Bittium, Telia

Funding: Business Finland

Duration: 1.1.2017-31.12.2018 (2 years)

Approach


In the 5G-SAFE project, we studied 5G-

inspired automotive use cases, benefitting

the society by improving road safety

Based on the use cases, a communication

framework and service prototypes were

developed and evaluated in field trials

Key elements of the 5G-SAFE solution:• Intelligent connectivity and data transmission

solutions for vehicles and infrastructure

• Distributed data processing (e.g. MEC)

• Novel road safety services that rely on sensor

data and information collected from vehicles and

other sources (e.g. weather stations)

Road safety pilots in the 5G testnetwork


Pilot 1: Advanced road weather services


Goal: Enabling sophisticated traffic

weather services via robust and extensive

data exchange between vehicles and

cloud

Benefit of 5G: Robust collection of

vehicle observations and timely delivery

of the services

Piloted services:• A weather forecast to avoid a bad route on

test track

• An airbag burst warning from another vehicle

• Friction data observed by another vehicle to

avoid slippery route on the test track

Pilot 2: Vehicle-to-vehicle video for improving road safety

VTT – beyond the obvious

Goal: The front view of a vehicle is transmitted

from the first vehicle of the queue to the others,

providing visual information of the road ahead

during poor visibility

Benefit of 5G: 5G supports high bandwidth,

reliable and low latency data transfer, essential

for V2V video streaming

Piloted services:• A test vehicle driving on the test track was sending

out video from its dashboard camera. The driver of a

vehicle travelling behind the first one watched the

vehicle camera view received from the front vehicle.

• Receiving a live video stream from an arctic truck

fleet, when it was on the move

Pilot 3: Optimizing road maintenance


Goal: Improving road maintenance with novel

services that enable automating road inspection

tasks for the road maintenance management

and quality control

Benefit of 5G: Crowd-sourced data (e.g. video)

can be collected in real-time for road

maintenance purposes with reasonable costs

Piloted services:

• Data collection and analysis model for

detecting maintenance needs. Remote

inspection using video.

• Detecting snowy traffic signs from vehicle

camera data

• Snow plough scheduling solution based on

mobile observations and weather forecast

Pilot 4: 5G-assisted automated driving


Goal: Improving the situational awareness

and safety of automated vehicles with road

weather and road condition information

Benefit of 5G: Enhanced uplink capacity

for vehicular data communication (e.g.

LiDAR) and low delays thanks to 5G and

edge computing

Piloted services:

• Robot car driving in automated mode on the test

track receives a slippery road warning and

plans its route accordingly

• Robot car receives an up-front warning of an

obstacle from a MEC server and is able to take

action to avoid it


5G and edge computing will be key enablers for

novel connected vehicle applications that can

improve road safety

Essentially, they will enable scalable and reliable

communication and processing of vehicular

sensor and camera data in real-time for localized

and more intelligent services

First pilots in the 5G test network with real

vehicles attested the feasibility of the 5G service

concepts

The work continues in the follow-up project:

• Exploiting fully current and upcoming 5G, cloud and IoT

technologies in the service development

• Disseminating the results in key forums

Schedule & budget:

• Celtic-Next label received on 14.11.2018

• A 3-year project, Finnish consortium KO held on 14.1.2020

and international KO to be held on 1.9.2020

• Current countries: Finland, Canada and Romania

• Budget in Finland: 5.7 M€ (~38.5 PY)

Use Cases

UC1: “Road weather, safety and

maintenance services”• Novel road weather, safety and road maintenance

services enabled by 5G. The services rely highly on data

(incl. video) collected from vehicles (e.g. crowd-

sourcing) and roadside sensors as well as to the

intelligent real-time processing of the collected data

(e.g. AI).

UC2: “Hybrid connectivity for extended

service coverage and reliability in remote

or rural locations”• The usage of more than one network technology (e.g.

C-V2X evolution, ITS-G5, 5G/satcom) for extending the

coverage area and improving the reliability of the services

considered in UC1 and UC3. Adaptation of the services

and data transmission to the network capabilities. Figure: VTT’s sub-use case for obstacle detection

and notification using hybrid connectivity.

Use Cases (cont.)

UC3: “Ultra-low delay/high reliability

services for autonomous driving,

focusing on road safety interactions

with vulnerable road users (VRUs)”• Services requiring low latencies and/or high

reliability in ensuring the safety of automated

vehicles. Communication between vehicles and

VRUs considered to further improve safety.

UC4: “Cyber security”• Services to detect and block cyber-attacks to

CAVs and smart transportation systems. Sharing

information about such attacks with fleet

management systems to develop system-wide

defense strategies.

warning and negotiation.


An intersection is a complex scenario for automation:

interaction is required with traffic lights and sensors covering blind spots
