TIAH users can download additional intersection blocks from the TIAH website (tiahelper.com). Several pre-configured different "looks" of the intersection volume symbol are available. Note that only the blocks provided with the TIAH setup program have the full attribute set, i.e. they allow automatic insertion of intersection's street names along the edges of the block. The additional blocks can be easily modified to include this feature - see the Help section on Customizing Intersection Volume Blocks.
The following is a sample of the symbols⁄blocks that can be downloaded from the TIAH website. To enable the blocks for use with TIAH, just place the Intvol blocks in the “C:\Program Files\INTVOL” directory and place the arrows in the “C:\Program Files\ARROWS” directory. Restart TIAH and the blocks will be available for selection.
