These are some VMS feature requests, mostly resulting from German TLS specification (but is not a complete cross check).
- As far as I can see, pictograms cannot be associated with a specific lane (e.g. different speed limits for each lane). The lane attribute should be introduced in VmsPictogramDisplayCharacteristics.
- Proposals for VmsDatexPictogramEnum:
- snow maybe complemented by fallingSnow and snowOrIceSleekness
The model sees a VMS Unit controlling Single VMS
Defining a Message as an elementary information displayed by a single VMS, in this model any visual information like pictogram associated to a single lane which may represent a single information is seen as a VMS itself each of them is modeled with one or more picto depending on the device ( pictogram such as full color pixel matrix or simpler lane traffic light may be associated to the same Lane VMS, controlled by a single VMS unit )
so the actual model has Lane VMS, not Lane pictos: a single picto is to be modeled as a VMS.
