eMobility – Strategic Applications AgendaAnnex BCommunication technologies used in cybercars:Various communication schemes have been used and are now operational on various systems: GSM andGPRS mostly for communicating with the users through their mobile phones, and Wi-Fi (IEEE 802.11) forthe communication between vehicles and infrastructure. High bandwidth communication is needed incase of transfer of images, for example for remote control of the vehicles.http://www.cybercars.org/docs/CyberCars%20Final%20Report-V2.pdf – final reporthttp://www.cybercars.org/indexold.htmlhttp://www.adase2.net/Commercial and economic issuesSupplierLow volume production meant high costs.Technical issuesSupplierVehicle controls: limited performances and especially poor reliabilityNavigation and guidance: problems existObstacle detection and avoidance: vision system solutions not robust enough for implementation intocybercar without human intervention. Laser sensors had limitations in terms of performance and cost.Vehicle platooning: only limited experience was available on this topic.Fleet management: problems with vehicle distribution versus demand.Unpredictable environment in city (vehicles, pedestrians) caused problem for remote driving.5. Composition Of Mobile Pre-trip, On-trip Services(COMPOSE)BackgroundProject Duration 28 months, starting from August 2002.The COMPOSE project aims to define the specifications and demonstrate an innovative mobile service package fortravellers based on the full integration of the mobile Pre-Trip (3D navigation in city environment) and On-Trip (incarlocation based & satellite broadcast/multicast and last mile) service components. COMPOSE offers the fullcoverage of mobile users needs during the pre-trip and on-trip phases through a single access point forcontinuous information broadcasting (weather forecast, news & sport, cultural & entertainment information) andon demand information (messages, points of interest, route guidance, dynamic traffic information). COMPOSEaims to overcome the drawbacks of state-of-art solutions by pursuing a service-integrated approach thatencompasses pre-trip and on-trip services considering that on-trip services could be split in in-car and last-mileservices:pre-trip services, whereby users access the COMPOSE platform by both fixed PC and PDA. In the former theuser can perform a virtual tour (3D application) by navigating on a rich Geographical Information environmentrelated to a selected area (trip itinerary and time) as well as access the Personalised Travel Information Services(weather, news, etc). In the latter the user can access to dynamic route planning and traffic information as wellas messaging services.(on-trip) in-car services, whereby users can get wireless-link access by PDA to both broadcast/multicast onewayservices and point-to-point two-way services (location based services)Satellite Broadcast/Multicast Services: (on-way services) information is delivered at low data rate through S-UMTS capability in order to provide continuously updated information. This approach will allow quasi-real time131
