1. In the File menu, select the Import > Emme entry.
The Emme import window opens.
2. Select the Basic settings tab.
3. Make the desired changes.

Format of the input files |
Select the UTF 8 or ANSI format. Separator Select the desired separator to be used when importing the files for shapes and extra attributes. |

Co-ordinate system in the target network |
Visum (no projection) If this option has been selected, you will switch to the Visum coordinate system. Neither the coordinates nor the display will change. From file If this option has been selected, you will switch to a pre-defined coordinate system. Use the adjacent button to select the desired coordinate system in the Projections window. Note Make sure that the selected coordinate system matches your data. Unit of coordinates in the source network From the drop-down list select the units used for Emme coordinates:
Factor Factor by which the Emme values are converted into the units used in Visum. Note Visum adopts the coordinates unaltered. The network scale is adjusted to reproduce the coordinate and length conditions correctly (Editing the coordinate system and scale). |
| Lengths and speeds in the source network |
From the drop-down list, select the units used for Emme length and speed data.
Factor Factor by which the Emme values are converted into the units used in Visum. |
| Allocation of link attributes |
Here you can set the PrT capacity and speed. Capacity PrT From the drop-down list, you can select whether links featuring a constant PrT capacity are to be imported or whether the value of an Emme user-defined attribute is to be adopted for the PrT capacity per link. If the constant option is selected, enter the value of the PrT capacity in the input field. v0 PrT From the drop-down list, you can select an Emme user-defined attribute whose value is to be copied per section for the speed in the unloaded network. Note For links Visum interprets parameter a in Emme files and automatically inserts both directions of a link with the same attribute values. |
|
Modeling of connectors |
Create a zone and a node for each Emme centroid If this option has been selected, a zone and a node are created for each Emme centroid as well as a connector that links the two. For all Emme links from/to the Emme centroid, links from/to the new node are generated. Only create a zone for each Emme centroid If the option is selected, Emme centroids are read as zones only. Visum generates a zone and per Emme link a connector. |
|
PuT supply |
Generate both line directions from line data
Note The layover time (“lay“) specified in Emme is used to determine where a line route begins or ends in Visum. If a layover is specified within the course of an Emme line route, Visum creates two directions, i.e. two line routes. If a layover is specified at the end of the course or not defined at all, Visum generates just one direction and one line route.
|
If this option has been selected, both directions of a line route are generated based on Emme line data. 
If the option has not been selected, only one direction is generated.4. Select the Files tab.
5. For each Emme data file type for which you want to import data, click the corresponding column and then click the button 
that is now visible.
The Open file <file type> window opens.
6. Select the desired file.
7. Click the Open button.
File name and directory are used for the File name entry.
8. Select the Transport systems tab.
|
Notes: The settings of the Transport systems tab are only available if you have selected an Emme modes file for import. If an Emme modes file has been selected for import, Emme transport systems are automatically allocated to Visum types of transport systems applying the following rule:
|
9. If necessary, you can change the allocation of Emme transport systems to Visum transport system types in the column Type (Visum) of the drop-down list.
10. If necessary, change the settings for Public transport routing using the button 
in the column of the same name (Reading a network file with incomplete line routes or system routes).
|
Notes: One mode and one demand segment are automatically created for each PrT transport system. Only one mode and one demand segment are created for all transport systems of the type PuT, PuTWalk, and PuT-Aux. If no PuTWalk transport system is imported, a standard transport system PuTWalk is generated which is permitted on all connectors, yet on no links. |
11. Select the Demand matrices tab.
|
Note: The settings of the Demand matrices tab are only available if you have selected an Emme modes file for import. |
12. For each demand segment for which you want to import an Emme demand matrix, click the corresponding column and then on the now visible button .
The Open: Matrix file for... window opens.
13. Select the desired file.
14. Select the PuT run times tab.
|
Note: The PuT run times tab is only available if you have selected an Emme transit lines file for import. |
15. Make the desired changes.

Description |
|
Index |
Index number of the TTF function to be imported (Transit Time Function) for calculating the speeds of the line routes. It is read from the selected Emme transit lines file. |
|
Link attribute |
You can specify whether the speed of the line route is to be constant or whether it is to be calculated from a link attribute and a factor. The button allows you to select either the Constant speed or any link attribute in a separate window. |
|
Factor or speed |
If Constant speed has been selected as link attribute, enter the speed value. If any link attribute has been selected, enter a factor the attribute value is multiplied by. |
|
Notes: For each imported Emme stop of an Emme line, Visum creates a node, a stop, a stop point, and a stop area - the stop area being allocated to the node. Since Emme does not distinguish between stops and nodes (stops, zones, nodes = “centroids“), each centroid in the course of a line route is interpreted as a stop unless it is explicitly stated in Emme that the line route does not stop at this point. Incomplete Emme line route courses can be completed similarly as to reading networks (Reading a network file with incomplete line routes or system routes). |
16. Confirm with OK.
The selected Emme data is imported.
