  1. V2V and V2I communication: SODIT experimentation Jean-Jacques HENRY President , SODIT 11 September,2010 SODIT (Société pour le Développement and l’Innovation dans le Transport)

  2. Agenda • Introduction of SAFESPOT Project • Examples of Application areas • Key challenge: Communication V2V and V2I • Achievement and beyond

  3. SODIT: • Consulting firm in traffic /transport • Involved for long time in European projects • Connect to China through Paristech • Responsible VIAJEO project Shanghai coordinated by ERTICO • Involved in SAFESPOT project (Safespot and CVIS led by ERTICO, two biggest projects on vehicle safety )

  4. SAFESPOT project-Traffic Safety • 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 OPERATORS • SUPPLIERS • 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) • 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 an • Intelligent Cooperative System based on • Vehicle to Vehicle (V2V) and Vehicle to • Infrastructure (V2I) communication

  5. 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.

  8. 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) Some typical use cases: Safe lane change maneuvers Road departure Cooperative situation awareness and extended collision warning Cooperative tunnel safety Road condition Information Cooperative maneuvering Predictive speed reduction

  9. Work achievement SODIT within SAFESPOT Project

  10. 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

  11. 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

  12. Signal priority system for emergency vehicles at crossroad This product « signal prioritycontrollor »isused in Chongqing for pumper

  13. 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)

  14. IHM: Message operation in AEV Slow down

  15. 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

  16. Key challenge: Communication V2V and V2I • VANET = Vehicle Ad hoc Network which in charge of establishing and maintaining the network connectivity for the V2V and V2I communications. This sounds very convincing, however … … For communication you need a common language  standardization Classical reference scenarios for the C2C-- CC

  17. 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 Frequency band in 5.9GHz is reserved by European countries!

  18. 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.

  19. 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

  20. 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! 索迪特（北京）科技有限公司 ：北京市海淀区善缘街1号3栋Address7层 Tel：010－68005266  Fax：010－68005366 Zip code：100088
