3.3.2 Road infrastructure
The SCT has a classification for the Road infrastructure in Mexico. In this classification the
roads are divided into five classes:
- Road type 1: Highways
- Road type 2: Primary roads
- Road type 3: Secondary roads
- Road type 4: Rural roads
- Road type 5: Access roads

The traffic classes are determined on the basis of the expected traffic intensity. For this study
the same classification system will be used. In figure 3.3 the road infrastructure of Tabasco is
shown.

Road type 1: Highways
The truck traffic intensity is around 750 per day,
each direction. The number of cars is estimated to
be 12,000 cars a day in one direction. The width of
this highway is approximately 24 meters. The total
length of highways in Tabasco included in the model
is 191 km.
