Visum12.5 introduced the AddIn 'Import TransCAD network', found in: Scripts -> VisumAddIn -> Import
The interface handles following network objects: nodes, zones, links, turns, connectors and PuT lines. Please note: importing PuT lines needs manual editing afterwards, because of differences in the data models between TransCAD and Visum.
The interface needs files in formats, which can be exported from TransCAD: - ESRI shapefiles for the network's topology and geometry. - ASCII/TXT on turns.
Necessary files: 1) ESRI shp for nodes (including the shx and dbf file). 2) ESRI shp file on links (including the shx and dbf file).
Optional files: 1) ASCII text file holding turn times and closed turns. 2) ESRI shp file holding stops and the order they are served (including the shx and dbf file) [needed to import PuT data]. 3) ESRI shp file on routings (including the shx and dbf file) [needed to import PuT data].
