EMME/2常见问题解答5：Questions on EMME/2

   modify, you can use the graphic worksheet (Module 2.12).

You can punch the links to be modified (Module 2.14), edit the batchout file and read the new file in batch (Module 2.11).

If the new values are contained in a file which is NOT in d211.in format, use option 3 of Module 2.41 to input the values in batch.

If the modifications are systematic, you can use Module 2.41 and save the result of the expression (which can be a constant) in an attribute. In the link selection, be sure to include only the links to be modified.

5.1.4: I would like to initialize my base network and read a new d211.in file but I am not allowed to because there are turns (and/or transit lines) already defined. How can I read my file without losing my turns (and/or transit lines)?

This is not possible due to the hierarchy of the data bank: modes (and vehicles), nodes, links, turns, transit lines (see the EMME/2 User's Manual, Chapter 3, Figure 3-1). You should thus proceed as follows. Punch all turns using Module 2.31, then delete all turns. Punch all transit lines using Module 2.24, delete all transit lines. Initialize the network, read the new d211.in file and read back the turn and transit line batchout files. Turns and transit lines which are not compatible with the new network will generate errors.

5.2 Network Plots

5.2.1: How do I change the size of arrowheads on network plots?

The size of the arrowheads can be modified in Module 1.23. The default size is 2.0. Using 0 will give links with no arrowheads.

5.2.2: How can I obtain a plot where nodes are connected by only one vector (even if two-way links exist) and with no arrowhead?

Use Module 1.23 to set the size of the arrowheads to 0. In the desired modules, set the module parameter Offset to the right for links to 0.

5.2.3: Once I have a plot, how can I zoom out?

Use the graphic command w followed by a number be
