Place the cursor over an intersection for which you want TRAFFIX™ to make LOS calculations. Use the ctrl-click keystroke to select the intersection; the square around the intersection icon should change color to indicate that it has been selected. Do this for each intersection that you wish to be included in the analysis.
If you want to select all intersections for inclusion in the analysis, place the cursor over any one of the intersection drawing tool icons and RightClick. On the pop-up menu which appears, choose “Select All For Evaluation”.
