To prevent road accidents developing a “Safety Margin Assistant” that :
• detects in advance potentially dangerous situations,
• extends “in space and time” drivers’ awareness of the surrounding environment,
The Safety Margin Assistant will be anIntelligent Cooperative System based on Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication
Project type: Integrated Project (IP) 4th IST call of the 6th European Framework Program
Consortium : 51 partners (from 12 European countries)
OEM ( trucks, cars, motorcycles)ROAD OPERATORSSUPPLIERS
RESEARCH INSTITUTES UNIVERSITIES
Promoted by: EUCAR
Timeframe: 1/2006 – 07/2010
Overall Cost Budget : 38 M€ (European Commission funding 20.5M€)
IP coordinator : Roberto Brignolo C.R.F. (FIAT RESEARCH CENTER –Italy)
SPECIFIC OBJECTIVES
• To use both the infrastructure and the vehicles as sources (and destinations) of safety-related information and develop an open, flexible and modular architecture and communication platform.
• To develop the key enabling technologies: ad-hoc dynamic networking, accurate relative localisation, dynamic local traffic maps.
• To develop a new generation of infrastructure-based sensing techniques.
• To test scenario-based applications to evaluate the impacts and the end-user acceptance.
• To define the practical implementation of such systems, especially in the initial period when not all vehicles will be equipped.
• To evaluate the liability aspects, regulations and standardisation issues which can affect the implementation: the involvement of public authorities from the early stages will be a key factor for future deployment.

SAFESPOT applications will allow the extension of the “Safety Margin” that is the time in which a potential accident is detected before it may occur (e.g. in static and dynamic black spots, in safety critical manoeuvres)

Example of Application area: SMAEV•SMAEV =Safety Margin of Assistance and Emergency Vehicle
enhance safety and efficiency of Assistance and Emergency Vehicles (AEV)
Optimize management of AEV

Use case 1: Trafic light intersection priority• Approaching emergency vehicles send out a message to
traffic light controller (TLC) in its vicinity for priority
• Receiving TLC can automatically transfer to priority sequence in order to let the emergency vehicle could continue its way without stopping

This product « signal priority controllor »is used in Chongqing for pumper
Signal priority system for emergency vehicles at crossroad
Use case 2: Assistance vehicle warning incoming vehicles• AEV (Assistance and Emergency
Vehicle) reach the site where an event (accident, road maintenance, congestion).
• AEV send out an alerting message via wireless network (VANET) to RSU (Road Side Unit).
• RSU broadcasts a message containing instructions of speed limit, number of lanes affected and the position of the obstacle (or the distance up to the event)

Slow down
Test sites and results• Test sites: rural &
highway• Application
Communication range from 250meters to 850 meters
• Warning received on time by driver
• Drivers feels▫ Bring new information
about event driver will face soon
▫ Reliability of the information provided
▫ Reliability of the communication range (context dependent)
• Stackholders feels▫ Increase road workers
safety▫ Prevent over accident by
warning incoming drivers

Key challenge: Communication V2V and V2I
This sounds very convincing, however …
… For communication you need a common language
standardization

Classical reference scenarios for the C2C-- CC
• VANET = Vehicle Ad hoc Network which in charge of establishing and maintaining the network connectivity for the V2V and V2I communications.
Norm & standard for communication•Reliable, fast, secure, potentially low cost protocols for local
V2V and V2I communication
Technology : IEEE 802.11p
Need for dedicated frequency band in the 5.9 GHz. range
for secure
V2V and V2I, avoiding interference with existing
consumer links
Aligned to C2C-C and CALM standardization groups

Achievement and beyond
•The “dynamic vehicle net” and the “vehicle to infrastructure net” extend the operative range of the actual on-board vehicle systems and allow the driver to receive the information on possible acceptable manoeuvre or to continue to maintain the same behaviour avoiding the critical situations.

Future: Traffic signal violation warning• Traffic lights can send out their timing and phase to
prevent red light violations and potential accidents• Vehicles can be warned about an imminent change of a
traffic light and if they are in danger of running a red light• Conductors can be recommended to turn off the engine if
the waiting time is long

Future in China
•Implantation SODIT in Beijing with hope to
extend the marketplace of China for SODIT
become a major partner in the development of ITS with you all!
