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

Approach
28/08/2020 VTT – beyond the obvious
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
28/08/2020 VTT – beyond the obvious
Pilot 1: Advanced road weather services
28/08/2020 VTT – beyond the obvious
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
28/08/2020 VTT – beyond the obvious
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
28/08/2020 VTT – beyond the obvious
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
28/08/2020 VTT – beyond the obvious
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:

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.

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
