Who should use this document
This document is for use with TMT version 1.8 or greater. Do NOT use this document if you are working with a TMT version less than 1.8.
Summary of changes in this version
This version of the Tile Mosaic Tool contains updates to the tile model library.
Obsolete models
The most significant change is that some tiles are now considered obsolete. Obsolete models are contained within the tile category 'Obsolete'.
It is strongly recommended that worlds using obsolete models be revised, as future versions of the Tile Mosaic Tool may not include those models.
If a world.mos file contains tile models that are missing from the library and it is saved, that .mos file will become corrupted.
There is currently no way to recover from this condition.
The Obsolete tile category is included with this version to permit replacing obsolete models with compatible tiles.
A list of compatible models is included in the Appendix of this document.
Transition tile category
Another change is that transition tiles are now grouped into a new Transition tile category. If you require a transition between different roadway types, the Transition category is the place you will find it.
New tile models
Another change in this version is the addition of tile models, listed below.
bike_lane This is a new tile category. Tiles within the bike_lane category contain bicycle lanes, which are narrow lanes defined as Vehicle Restricted lanes. This definition is intended to prevent typical ADOs from using this lane.
However, scenario authors should be able to author pedestrian and bicycle models that will use the bike lane. In some cases it may be necessary to author scenarios using the standard road lane and apply a lane offset to shift the scenario object over into the target lane.
bike_lane tile models
- 2ln_3Mi_01
- 2ln_3Mi_02
- 2ln_4way_3Mi_01
- 2ln_4way_3Mi_02
NOTE: Bike lanes are not necessarily included as a separate network adjacent to the road network. At this time they are an attribute of the road.
Appendix A
Obsolete and compatible tile models
Do NOT use obsolete tile models - instead, locate the compatible tile model and use that instead. Obsolete models are included solely to avoid potentially corrupting existing world.mos files.
