The 2.11 Toolbox is designed to run in a generic UNIX environment with any of the common command shells. It also requires the following software:
- ArcInfo Release 7.03 or above
- EMME/2 version 6.0 or above,¹ running on a PC or a workstation
- Perl 4.0 or above
- HTML browser capable of displaying tables, for viewing the documentation
(1) Strictly speaking, EMME/2 is not required to run the Toolbox, but there is little point in using the Toolbox without a Transportation Simulation package available.
