In-Depth Information
the terrestrial transport of people. The objective is to facilitate access to multi-mode
information for a user wishing to make a trip.
Indeed, the user is often confronted with an ensemble of disparate information
(times and fares issued by the different operators, cards or tickets, etc., on paper,
interactive terminals or by Internet) which sometimes turn out to be difficult to
integrate into a specific and unique plan for a trip, adapted to their needs and
preferences. In this context, personalization turns out to be a promising approach to
take up this challenge. In the context of information to users, which integrates
several modes of transport and their connections, our objective is to help the user in
his approach to an information search and to provide him with a personalized result,
i.e. all the necessary information and only the necessary information. The user
provides the starting place, the arrival place and the arrival time. The system
suggests an itinerary to him according to his preferences. The user has the
possibility of validating the proposal or choosing another itinerary.

Scenario
The scenario acting as a base for illustration of the concepts is the following. It
deals with the transport network given in Figure 3.4, simplified on purpose, but
initially based on real data. In fact, it would have been possible to add other modes
of transport, both current and future (see Chapter 1 on this subject): these modes can
be individual (bicycle, rollerblades, electric or non electric wheelchair, Segway,
etc.), public (tramway − one is being inaugurated in Valenciennes in parallel with
our simulations), cyber-vehicles [MEL 10], [SER 08], auto-sharing, etc. Other
modes, such as the taxi or carpooling, can be considered, both individual and public,
according to their management system.
Thus, this simplified network (see Figure 3.4), describes the connection points
enabling a user to carry out a trip from the LAMIH laboratory at the University of
Valenciennes and Hainaut-Cambrésis, to the Archimed company in Lille
(Valenciennes and Lille are two towns separated by 60 km). Three transport
operators intervene in the realization of the journey:
- Semurval (bus operator), at the time of our first simulations, ensured the
movement of the user in the town of Valenciennes and its surroundings. The
transport modes considered in this scenario are mainly the bus, the car and walking.
- Transpole (bus and metro) is set up in the region of Lille. The transport modes
considered in this scenario are mainly the bus and the metro.
- The SNCF (train) links the two towns of Valenciennes and Lille by the TER
(regional express train) of the Nord-Pas-de-Calais region. We have also included the
