Refresh Data

The "Refresh" command can be used on exhibits where the user has already inserted all of the intersection volume symbols corresponding to the intersections for which volume data are being re-populated. This function is very useful for updating your volume exhibits once the traffic model ⁄ intersection volumes have been updated (but the number and IDs of the intersections remain the same).

Once in the exhibit layout:

1. Select the AM File and (optionally) the PM file

2. Click on the "Refresh Data" button in the lower right hand corner of the main toolbox

As long as the AM and PM files contain data for intersection IDs that correspond exactly to the intersection symbol IDs already present in the layout, TIAH will re-populate the volume symbols with the new volume data.
