Driving directions in macroscopic nodes
Macroscopic topology allows to model driveable train paths on a basic level: either there is a connection or there isn't. Without a microscopic topology (track level) it is not possible to identify possible direction changes of the railway vehicle when following this train path. It would be beneficial to have this information included in macroscopic topology.
For TMS/operational purposes it is interesting to know whether a train has to change its direction in an operational point as this will require some more time than just an ordinary stop.
railML 3.1 topology is based on RTM providing elements to connect different topology s. These elements can be specified w.r.t. usability with the attribute @navigability. The possible values of this attribute ("AB", "BA", "both", "none") allow only a basic interpretation of the driveability. A required change of driving direction cannot be derived.
