4.2.3. For the
tertiary roadway network system
The influence of the way is generally fixed at 11 meters, but
could be modified during the studies of preliminary draft according to the
constraints of the site. The roadway will thus include two lanes of 3 m,
broadsides each by a pavement which can go up to 2,5 meters of width, the
gutters included. In the retail parks and near the schools, the pavements will
have to be broader, contrary to the residential zones.
In tertiary roadway system and in zone 30 in particular, one
can admit a distribution of the widths which makes slow down and which
increases the width of roadway to 5 meters, even 4,5 meters when it is about an
urban court and the vehicles cross with the step.
