Transportation Systems & Mobility

Major recent evolutions in Intelligent Transportation Systems (ITS) are linked to rapid changes in communication technologies, such as ubiquitous computing, semantic web, contextual design. A strong emphasis is now put on mobility improvements. These improvements concern both the quality of traveller's information systems for trip planning, the ability to provide real time recommendations for changing transportation means according to traffic information, and the quality of embedded services in vehicles to provide enhanced navigation aids with contextualised and personalised information.

Web 2.0 technology plays now a role of growing importance, as it supports users feed-back which becomes a mean for improving quality of travelers information sytems. Exchange of information between users about delay, cancellation and other occurring events provides more accurate and precise data on the current state of the transportation system.

Let us cite various projects where AxIS was and is still involved:

• Mining Mobility Data, PREDIT (2004-2007): the MobiVIP project has been an opportunity to collaborate with local Institutions (Communauté d'Agglomération de Sophia Antipolis - CASA) and SMEs (VU Log) and apply AxIS know-how in mining spatial and temporal data issued from vehicules equipped with GPS and from the reservation server and in clustering trajectories (with semantic distances). Even if we didn't apply our know how in mining data streams in this project, this will be crucial in the future with more and more vehicules equipped with GPS.

• Traveller's Information Systems - evaluation of two Web sites (2007-2008):

  • the Envibus web site provides information about a bus network ; its evaluation was done by coupling ergonomic analysis and usage mining

  • the Otto&co web site supporting car-sharing. Our cooperation about car-sharing developed in 2008 with an evaluation of the Otto&co site in the context of the action COLOR Cuscov is still lasting.

• Advanced Transportation Systems - Multimodality, PREDIT (2010-2012): the TIC TAC project (cf. 8.1.7 ) aims to optimize travel time by providing, in an area with weak transportation services, a just in time on demand shuttle, based on real time information.
