Abstract: A scientific coordination group devoted toIntelligent Transportation Systems has been set up in theBrittany region, called "GIS ITS Bretagne". This group fderatesresearch projects as wiell as innovative actions and experiments.The objectives of this group are desciribed in this paper, as wellas two first projects: CA-PT1V an LoCoSS which are respectivelydevoted to intelligent signaling infrastructures and vehicles andgeolocation and transmission services for terrestrial andmaritime rescue applications.

I. OVERVIEW OF TBE GIS

The existence of a significant research task force incompnter science, comnpnter engineering, electromcs, signalprocessing and telecommnnications in Brittany has recentlyled to the setting of the scientific interest gronp called "GISITS Bretagne" devoted to Intelligent Transportation Systems.It amnalgamates research units of unnversities (Rennes andNantes), gradnate enginering schools (ENST Bretagne,ENSSAT, ENSIETA, INSA de Reimes), the Miiistry ofEqnipinent (CETE. LRPC. LCPC) and Fmnce Telecom R&D.After the signatnre of the agreement betWeen the partners inJune 2004, the GIS was officially launched in February 2005.

Its main objective is to stimnLlate and federate researchprojects as well as innovatiive actions and experiments usingtechnological platforms. Moreover, it looks for synergies withother structLres at the regional, national or interational levels.It is strongly related to social needs in particular secnrityissues by means of technologies or services (e., usingembedded devices). One of its important missions is to attractand associate (big, medium range and small) companies in theR&D activities which will be nndertaken.The ITS domain is broad and the first discussions have

focused on the identification of a priority: services to mobileusers. This theme covers several issues and two projects(which are detailed later on) have been recenty initiated andthey have received fnnding by the Regional Council ofBrittany. The LoCoSS project deals with geo-localization.conmnmication and rescue services and the CAPTIV project

aims at stndying and developing intelligent signaling systems.Other research activities are planned in 2006 and projectsabout "real-time" transport on demand and dynamic ronte aidcalling on distributed heterogeieous information systemsshonld be defined.

II. THE CAPTIV PROJECT

CAPTIV research project aims at proposing new low-costenergy-efficient mobile cominnnications solntions to ease andmake safer road traffic conditions. Considering "intelligent"road signs and vehicles. i.e. eqwpped with an antonomonsradio conunniication system, drivers will be able to receivevarious information about traffic fluidity or road signidentification at any time.

In order to rednice deployinent cost and increase lifetime Ofthe whole system, Mnltiple-Input Mnltiple-Outptit (MIMO)signal processing techniqnes are nsed. Such techniques allowto dranaatically increase the capacity of mobilecoMnnication systems or the qnality of the transmission,thanks to the well known space-time codes. From anotherpoint of view, MIMO systems allow to significantly reduceenergy consumed by connmnications in ad-hoc networks.Considering each crossroads as a cominnnication node, thepossible co-operation between road signs allows energy-efficient communications between crossroads (see figure 1).

Supported by the Scientific Interest Group GIS ITS-Bretagne and by industrial leaders in ITS domain, regroupingmajor research laboratories in the region, CAPTIV is a highiyapplication-oriented program. A first prototype of such acommuniicating crossroads will be presented in the Route duFutur in Saint-Bricnc (portion of road devoted to ITSexperiments).

Fnrther research on MIMO chainels characterization andmodeling, on specific antenns conception, associated withsignal processing teclmiqnes will then allow to optiniize theenergy consnmption between nodes. Comparisons to otherradio solntions, snch as RFID (Radio FreqnencyIdentification) will also be envisaged.

III. THE LoCoSS PROJECT

LoCoSS aims at bringing significant improvements to therescue brigades operations, terrestial as well as man'time,thanks to ITS technologies.

In the case of an accident or a disaster occurrng either onthe road, in a factory, in a city. in a harbour or on a boatcruising close to the coast, three points are of the highestimportance: the rapidity of the intervention of the bnrgade, theexactness and the completeness of the critical informationwhich is available at the level of the headquarters vehicledthe possibility for the intervemng agenits to remain inpermanent contact wiith it. The idea of the project is tocombine the three basic ITS technologies, i.e. the wirelessconmunication the positioing and the geographicinformation systems (GIS), to facilitate and improve the abovementioned points.Numerous wireless communication technologies standards

(GPRS, Wi-Fi, WiMAX, DSRC, UMTS...) will be optimallyused in the project to offir a permanent IPv6 comiectivitythrough NEMO technology. Therefore, the headquartersvehicle will be able to downiload continuously before thedeparture to the site, during its traveld during tlh operation,the necessary information inito its database to steer efficientlythe operations. Wireless bidirectional links will also beestablished between tlie headquarters vehicle and somemembers of the team who could be equipped with apositionin pack, in order to trace their movements from thevehicle and to optirruse the operations inmagement. Since allpieces of equipment (in the vehicle and on the member of theteam) will be provided with a full IPv6 connectivity, theheadquarter will be allowed to directly request infonnationfrom them.Thanks to the positiongin technologies, based on EGNOS,

aided by additiona sensors to ensure a high level of integnity,the intervnemng vehicles will be able to navigate precisely aindaccurately up to the accident or disaster location and the mainstationary headquarters (typically the fire station) will beinformed precisely about their progress. For the difficult issueof tackiing the firemen inside a big site such as a factory of aship, novel positioning techmiques such as high-sensitivity orassisted GPS receivers, combined with inertial sensors or withWi-Fi triangulation will be expenmented.

Finally, novel dynamic geographic infonnationmanagement techiiques will be used to build and to update theon-board database that will be necessary to support theoperutions. This base will have be extracted from the main,but too big to be used onboard the headquarters vehicle, database existing at the fire station and will have to beintemctively updated in real-time during the progress of dierescue operations. thans to the wireless links establishedbetween all the main actors. A record of the vanous dataexchanged can also be extremely profitable after theopemtion, for trainig and teaching purposes, inside asimulation tool that some fire brigades already possess.

IV. CONCLUSION

The LoCoSS project, as well as CAPTIV, will last 3 yearsfrom February 2006 to January 2009. Although the corepartners are research laboratonies (from ENST-Bretagnel,IRISA22 ENSIETA 3 IRENaV4 LCPC5 IETR6 C E7 Oiest)SMEs in the field of mobile communication and embeddedelectromc equipmeit have already been contacted to join theproject.
