Scanning maps and site plans

The following steps outline the procedure for scanning maps and site plans:

• Maps and site plans to be scanned should include a north arrow and a linear scale.
• Create an overview map that shows all relevant nodes of the transport network which is to be examined.
• Use individual signal control plans for each intersection showing detector locations, if you want to insert detectors in Vissim.
• Ensure that the scanned plans have a high contrast.
• Maps and plans should be oriented to North direction.
• Use a copy machine to reduce plans in case they do not fit the available scanner.
• A plan in A4 format should be scanned with 300 dpi resolution. The bigger the plan and the higher the resolution the bigger the bitmap file size. The memory requirements of the background file, the load time in Vissim and the network setup increase with the growing resolution.
• Save the scanned background map to one of the supported bitmap formats (for example *.bmp, *.jpg or uncompressed *.tif).
