VISSIM 5.30-05 User Manual

Background Images
1. Maps and plans to be scanned should include a north arrow and a scale.
It is recommended to create one overview map that shows all
intersections to be modeled and individual signal plans for each
intersection showing stop lines and detector locations (if applicable).
2. Ensure that the scanned plans show a strong contrast.
3. Maps and plans should be oriented to North direction. In the case of
modeling a North-South corridor, another orientation could be useful.
4. Use a copy machine to reduce plans in case they do not fit the available
scanner.
5. An A4 sized map should be scanned with 300 dpi. Depending on the
speed of the computer also higher resolutions can be useful. Generally
speaking, the higher the resolution the bigger the bitmap file size and the
longer it takes VISSIM to load the bitmap and to refresh the network.
6. Save the scanned file to one of the supported bitmap formats (e.g. as
*.BMP, *.JPG or uncompressed *.TIF file).
