collaboration between INRETS and the University of Valenciennes, with the aim of
intelligent filtering of information. Based on a defined profile and according to a
user model, it consists of selecting the information and presenting it in a
personalized way, offering greater abundance and relevance than information of a
general nature.
In line with this approach, it is advisable to accompany the member of the public
during information research and when making a decision about modal choice. We
can, for example, cite a PhD thesis about an interactive system of help for
multimodal travel [ZID 06]. Furthermore, in order to avoid the traveler having to
consult several transport operator Websites to plan his journey, a PhD thesis
[KAM 07a] was aimed at conceiving a cooperative mobility information system
(CMIS) enabling this route search to be automated, thanks to an integrated
information system based on principles that come from multi-agent systems. The
CMIS therefore becomes an intermediary between different sources of
heterogeneous and distributed information on the one hand and clients on the other.
This system must be capable of both finding the right source of information to query
it according to various user requirements and grouping information together in such
a way as to meet requirements [KAM 05], [KAM 07b]. To provide an itinerary with
different components that is optimized according to criteria to be defined, the use of
distributed algorithms has been backed up in a patent [KAM 08].

Traveler information and adjustment to cognitive abilities and the situation
of mobility
For land transport, road information intended for road users has been around for
a long time and has seen a lot of public investment to ensure the safety and fluidity
of traffic in and around large agglomerations, heavy traffic roads and on motorways.
Moreover, personal navigation system equipment for car users that can supply
dynamic information concerning disturbances (onboard global positioning system or
GPS) has undergone a phenomenal development thanks to a better precision in
localization and regularly updated cartography. Even if the latest surveys show a
certain dip in its use, the automobile represents around 88% of mobility in France
(CCFA, Committee of French Car Manufacturers, 2007). The Mobilurb project
[JUG 05] completed the analysis of needs, both of the automobile driver and the
multimodal user, via an anthropological approach. The objective was to functionally
define a box to aid multimodal mobility. After having qualified the traveler action
processes in a disrupted situation, the specifications of a box were thought of, the
mission of which would be to provide an appropriate navigational aid and to
generate alternative routes when there is a disrupted situation. The originality of this
concept lies in its capacity to adapt itself to different user profiles
.
