What is a 1PC Licence?

1PC Licences for SIDRA INTERSECTION are per computer licences (computer based, not network or server based). This means that once it is activated on a computer, it cannot be simultaneously activated on another.

Benefits of the NETWORK model

SIDRA INTERSECTION offers a powerful NETWORK Model:

  • This allows users to model a Network with up to 50 Sites and no limit on the number of Networks modelled.
  • It is recommended for detailed modelling of paired intersections as wells as alternative intersections and interchanges.
  • Network Templates make setting up complex intersection and interchange designs easier and less time consuming.

In SIDRA INTERSECTION, modelling of more than two connected Sites is very common, for example, for modelling a road corridor, an interchange with a nearby intersection, a pair of wide-median intersections, and so on.

Network Templates of paired intersections, interchanges and various alternative intersections and interchanges are available in SIDRA INTERSECTION and many of them require a combination of more than two Sites in a Network, e.g. the Restricted Crossing U-Turn (RCUT) Intersection.

Both 1PC and FLOATING Licence Types allow modelling of Networks.
