Intersection Volume Symbols (Blocks)

The TIAH program is distributed with a basic set of intersection volume symbols (blocks) which are used to "store" and display the intersection volumes in your TIA report exhibits.

Each and every intersection block distributed with TIAH as well the additional blocks available on the TIAH website can be easily modified by the user to suit his or her graphical needs.

TIAH 4 Intersection Blocks

The following blocks are included with the TIAH 4 setup file. For additional blocks, please visit the TIAH website (free download). Note that the TIAH 4 blocks have been enhanced compared to the TIAH 3.x blocks, in that they now provide a means to show street names.

• Standard 4-leg intersection block:

• Standard T-intersection block (this example depicts a T-intersection without the southbound approach - a similar standard block is provided for the remaining three cases, i.e. no NB approach, no EB approach, and no WB approach):

• 4-leg roundabout block:

• 3-leg roundabout block this example depicts an intersection without the southbound approach - a similar standard block is provided for the remaining three cases, i.e. no NB approach, no EB approach, and no WB approach):
