This preliminary work enabled the issue of computerized management of
delivery areas, such as it is perceived by ICT specialists, to be harnessed. This
contribution was the starting point for the
Delivery area of the future
project, carried
out in the context of the competitiveness cluster LUTB (
Lyon Urban Truck and Bus
)
bringing together several participants of the cluster concerned by this issue. First
approved by the cluster and then submitted to the PREDIT 4 GO 4 call for tender, it
was accepted and financed by the ministry of Ecology, Energy, Sustainable
development and the Sea.
6.10. ICT in the dynamic management of road networks
A third study which we present concerns the dynamic management of road
traffic, which is regularly increasing, both in towns and outside agglomerations.
A first approach leads to development such as increasing the number of lanes;
the second aims to segment traffic according to categories (individual cars, heavy
vehicles, public transport, priority vehicles) by proposing specific development and
traffic rules, with in particular the creation of specialized lanes (bus, tram, trolley).
This second choice can lead to satisfying solutions on the condition that there is
enough space.
When space is lacking and the frequency of this type of specialized traffic is not
sufficient, there is a sense of waste and poor management. A third solution then saw
the light of day, that of the dynamic allocation of lanes to different types of
transport. A significant work of data gathering, analysis and classification was done
by J. Nouvier of CERTU (Centre for studies on networks, transports, urbanism and
public construction) [NOU 07].
He shows very varied solutions, from the more physical (the
ad hoc
movement
of low walls with trucks) to the more informational (signposts with variable
displays) enabling a greater or lesser rapidity of dynamicity.
Today it is true that telematic or embedded and/or mobile ICT can provide
solutions leading to a very large dynamicity (clear a lane for a bus or an ambulance
in real time) on the condition of sufficiently informing the different users and
ensuring both the respect of regulations in terms of transport (or suggestions to
modify it) and in particular the safety of all the users. Hereafter we give a brief
description of the ICT vision, in a system perspective, such as we see it in our
IMERA-HMTD logic. Figures 6.10, 6.11 and 6.12 present a number of situations
which seem interesting and more or less complex to implement.
