In-Depth Information
- make information available in the form appropriate to the task;
- enable the collaboration between different participants (signal traffic problems
such as accidents, dynamically re-allocate the journey in the event of a problem, ask
for an infracting vehicle to be fined, etc.).
The most important operations are the following:
- define the dynamic prohibition of truck circulation;
- know the current situation of traffic prohibitions for trucks;
- know the provisional occupation of the delivery areas involved;
- know the immediate occupation of delivery areas concerned and take action
(take the space if free, change a reservation, etc.).
The proposed solution is based on the principles previously described (HMTD
and IMERA) with three main concepts that we designate by the term MOCOCO
(mobility, collaboration, contextualization): the concept of mobility suggests using
miniature portable (or worn as an accessory) appliances offering appropriate
services which are applicable in the context of global communication. That of
collaboration (local or remote) brings the possibility of involving multiple
participants with diverse competencies, who are not necessarily co-localized, to
manage the particular situation. The concept of contextualization suggests making
contextualized information available at the site of the action and more generally to
all the users. Nomadism is taken into account by the use of lightweight appliances
which can access the system and which are connectable - disconnectable -
reconnectable and which support the user in his activities: these are
wearable
computers
or
handheld computers
.
The mobility of users is situated on the scale of the town or the agglomeration,
where it is a matter of ensuring the accessibility of the users or through them the
common information system and the delivery areas. The consideration of the
location is of utmost importance, not only geographically but also logically (in
proximity to a given delivery area for example). For this the notion of attentive
environment (which is alert to the situation), which we qualified beforehand as
augmented, is essential. Indeed, thanks to the sensors which observe the
environment and update the perceived state, the system knows the situation of the
moment and can take it into account.
Taking into account the context deals for example with the identification of
objects and users (who), the physical location of objects and users (where), and the
