Modes

The next step in using TREDIS is to select the Modes of transportation and the associated Purposes for your analysis. Using the check boxes contained on this page, simply check the box in the appropriate row and column.

The double downward arrow icon at the left side of a row indicates that there are detailed modes that may be chosen. Click on this icon to expand the list.

The blue Save button changes to orange to indicate a change has been made and the button needs to be pressed to save the change. Click Manage Modes button to open new window to hide, view, or edit Modes associated with the Contract you are currently using.

Add Custom Modes

Clicking on the Add Custom Mode Purpose Types bar will expand the screen to allow you to create a new mode-purpose combination based on an existing one.

Provide a name for the new Mode, select a mode type from the dropdown menu and then select an existing mode to use as the template to create your new Mode. Once you have created your new Mode, by clicking the Add button, you may then update the fixed factors using the Manage Modes button at the top right of this page.

Custom modes are shared among all users in your account. Once created they may not be deleted, though the creator may change the default characteristics of the custom mode.

Adjust Mode Factors

Clicking on the Adjust Mode Factors button allows you to change the project defaults for the modes selected in the project.

Only mode-purpose combinations selected are displayed and the changes apply only for the current project. Once you have finished entering your changes, click the Save button at the bottom of the screen. Use the Close button to exit the screen.
