Reading a network file with incomplete line routes or system routes

If the network file to be opened contained incomplete line routes or system routes (i.e. one or more link or stop point missing in the course of the route or being blocked for the route), you can pre-define how to complete the given data when read in.

1.  Open a network file or read network data additively (Opening a network file and Reading network data additively).

2.  In the Read network window, select the Show the 'Complete line routes' window option.

During the import, the Read network (completing the courses of line routes/system routes) window opens.

3.  Make the desired changes.

Note: When opening the Read network (completing the courses of line routes/system routes) window, the settings are read in for each transport system from the registry if they exist there. If for the transport system used, there is no registry entry but a registry entry independent of a transport system for the settings, then this is used.

Tip: Alternatively, save the settings for adding line route and system route paths under user preferences. These settings are then saved as default settings in the registry regardless of the transport system.

1.  From the Edit menu, choose User preferences.

2.  In the User preferences window, in the navigator, select Network > Lines.

3.  In the section Completing of line route course and system route course, click the button Edit default settings.

The window Read network (completing the courses of line routes/system routes) opens.

Element

Description

Transport system

From the selection list, select the transport system the settings are valid for.

Note

This option is not available when you open the window from within User preferences. Only the default settings are saved in the user settings, which have no reference to a specific transport system. These default settings are used when opening the window for additive network reading.

Delete existing line routes after reading

If this option has been selected, all lines defined in the currently open network and their corresponding data (line routes etc.) are deleted after the reading process.

Note

This option is only provided for Read network data additively (Reading network data additively).

Ignore line route item/system route item with unknown network reference

If this option is selected, elements that have a reference to a node or stop point, for example, that is not contained in the existing network are ignored.

Stop points section

If stop points on nodes do not exist

You can decide how to handle missing stop points in the route.

Do not create line route

If this option has been selected, line routes which should use the missing stop point of the node are not read in.

Use stop point of node

If this option has been selected, the invalid stop point number in the route read from file is ignored. The stop point defined (with identical number) for the node will be used instead.

Create stop point

If this option has been selected, a stop point with the node's co-ordinates, code and name is created for each node without stop point.

Notes

If there is a stop point already, the line route cannot be read in. No line route items are created for stop points on links.

If stop points are closed to this transport system

You can decide how data shall be adjusted if lines of the selected transport system are not permitted to serve certain stop points.

Do not create time profile

If this option has been selected, time profiles including stops at blocked stop points are not read from file.

Remove stop event from time profile

If this option has been selected, time profiles including stop events at blocked stop points are read from file but the stop point will not be served.

Open stop point to TSys

If this option has been selected, time profiles including stop events at blocked stop points are read from file and the stop point will be opened to the transport system, thus it will be served.

Links and turns section

Also use closed links for routing

Select this option to also include links closed for the transport system selected for routing.

Also use closed turns for routing

Select this option to also include turns closed for the transport system selected for routing.

If links are either missing or blocked for the transport system

Use course of existing line routes first

If the option has been selected, existing line routes are checked to complement the missing section.

Note

This option is only provided for Read network data additively (Reading network data additively).

If no path could be found this way or else

You can decide how data shall be adjusted if no appropriate line route course could be found due to missing links or blocked links.

Do not create line route / system route

If this option has been selected, the routes using the particular links will not be read from file.

Open existing link or use type to insert new link

If this option has been selected, blocked links are opened to the selected transport system and missing links are created. You can select the type for the new links in the drop-down list (Specifying link types) or insert a new link type with the default values using the symbol. The newly inserted type is then automatically selected.

Find shortest path

If this option has been selected, a route course is searched for which has to meet certain requirements (shortest path).

Parameters for the shortest path search

Search criterion

In the list, click the criterion you want to use for the shortest path search.

  • Link length (direct distance): direct distance link length from start to destination stop area
  • Link run time: transport system based run time on the link
  • Time from speed def. by link type: time calculated from the speed defined for the transport system on the respective link type
  • Link length: calculated link length if not manually adjusted by the user

If no shortest path is found or length is > [detour factor] x direct distance

You can decide how data is to be adjusted in the event that no route course is found that meets the specified conditions or if the length of the found route exceeds the direct distance between the two stop areas by the indicated factor.

Enter the desired factor in the input field.

Do not create line route / system route

If this option has been selected, line routes and system routes are not read from network file.

Insert only if a direct link can be opened

If this option has been selected, line routes and system routes are only read from network file if those links can be permitted for the selected transport system.

Always insert; direct link is opened if possible, otherwise it is inserted

If this option has been selected, line routes and system routes are read from network file. Missing links (Specifying link types) in a route course will be created. In the list, click the link type you want to use for newly inserted links.

Link type of newly created links

Here you specify the link type for newly inserted links.

Set the link type of open links to

Here you can specify a link type for opened links. This way you can tell later which links were opened during the read in process.

Apply to all transport systems

Click this button to apply the settings set for the currently selected transport system to all transport systems.

Note

This option is not available when you open the window from within User preferences.

Save parameters / Open parameters

Using the buttons you can save your settings in an *.crcx file or open saved settings. The format of the file is xml.

4.  Click the Next > button.

The network data is read from file and incomplete line routes and system routes are completed according to the current settings.

Note: Links that are created or opened for route completion will be logged to log file, as far as a log file has been opened (Specifying settings for protocol files).

Defining default settings for completing line route and system route courses

As an alternative to completing line route and system route courses as part of the additional import of networks, save the settings for adding line route and system route courses under User preferences. These settings are then saved as default settings in the registry regardless of the transport system.

1.  From the Edit menu, choose User preferences.

The User preferences window opens.

2.  In the navigator, select Network  >Lines.

3.  In the section Completing of line route course and system route course, click the button Edit default settings.

The window Read network (completing the courses of line routes/system routes) opens. You can define settings here that will apply across all transport systems.
