Adding network objects


Network objects include modes, vehicles, centroids, nodes, links, transit lines, segments and turns. Modes, vehicles and transit lines must be added using their respective table. The remaining objects can only be added from the network plot. In either case, the popup menu (displayed when you right-click the mouse) has an Add... option to add the relevent object. This menu option is only enabled if you are permitted to add an object. For example, if the EMME/2 database or current scenario is write-protected, or the maximum number of objects has already been defined, then the Add... menu option cannot be selected.

Adding Modes
Select the Mode Table and right-click to display the pop-up menu. If you are permitted to add a new mode, choose the Add Mode menu command and then select the mode type. You may only define one auto mode. The node identifier is a unique character.


Adding Vehicles
Select the Vehicle Table and right-click to display the pop-up menu. If you are permitted to add a new vehicle, choose the Add Vehicle menu command and then select the vehicle number and transit mode.


Adding Centroids and Nodes
Display the network plot,  zoom into the area where you are adding centroids or nodes and then choose the centroid (or node) layer. Right-click the plot and choose the Add... menu command. Note that the cursor changes to indicate that you are now adding centroids or nodes. Click on the plot where you wish to add a a centroid or node. You will be prompted to enter a unique node number. If you wish to stop adding centroids or nodes, press the ESC key or refresh the plot. If you press and hold Ctrl-Alt while clicking to add a node or centroid, then the object is automatically added using the next available node or centroid number.

Adding Links
Display the network plot,  zoom into the area where you are adding links and then choose the link layer. Right-click the plot and choose the Add... menu command. Note that the cursor changes to indicate that you are now adding links. Click on a node to start the link and then click another node to complete the link. If the 2-way links button is checked, then a two-way link is added. Otherwise, a one-way link is added. After adding one link, the second node becomes the first node of a new link and you can continue adding links. To finish adding links, either double-click in a vacant area anywhere on the plot or press the ESC key.

Adding Transit Lines
Select the Transit Table, move to the upper transit line table and right-click to display the pop-up menu. If you are permitted to add a new transit line, choose the Add Line... menu command and then enter a line name and transit mode for the new line.


Adding Segments
Display the network plot,  zoom into the area where you are adding segments and then choose the segments layer. You may also wish to set a transit line filter such that only the line where you are adding segments is displayed as well as a link filter such that only the modes for this transit line are displayed. You may only add segments at the end of a transit line.

Right-click the plot and choose the Add... menu command. Note that the cursor changes to indicate that you are now adding transit segments. Click on the node at the end of the transit line to start a new segment and then click the next node along the link to complete the segment. After adding one segment, the second node becomes the first node of a new segment and you can continue adding segments. To finish adding segments, either double-click in a vacant area anywhere on the plot or press the ESC key.

Adding Turns
Display the network plot,  zoom into the area where you are adding turns and then choose the turn layer. Right-click the plot and choose the Add... menu command. Note that the cursor changes to indicate that you are now adding turns. Click on the node where you wish to define a turn. If you wish to stop adding turns, press the ESC key or refresh the plot.
