TRANPLAN (TRANsportation PLANning) is a set of integrated programs for the transportation planning process. It encompasses the four-step travel demand model of trip generation, trip distribution, mode choice, and trip assignment for both highway and transit systems. The public transit software utilizes coding and analysis techniques similar to the U.S. Department of Transportation's Urban Transportation Planning System (UTPS). With it's English like syntax, TRANPLAN is extremely easy to learn and use.

NIS (Network Information System)

NIS is a flexible, interactive graphics editor for displaying and maintaining spatial data, including highway and transit network descriptions, and area (polygon) boundary data. It is driven by a set of icons and menus, which provide the user with a flexible set of thematic mapping tools. Networks and related attributes can be graphically displayed using colors and patterns. Polygon boundaries, (e.g. traffic analysis zones) can be defined and displayed with user control over color and patterns. NIS's flexible configuration options allow users to customize the software's operation.

TPMENU (TranPlan MENU)

TPMENU combines TRANPLAN functions, NIS and supplementary software to provide an integrated user interface. The menu system allows the transportation analyst to run complex models without having to understand the specifics of the computer operating system or the software command language. Any person familiar with TRANPLAN syntax and operating system commands can develop a customized TPMENU system to support a specific area's planning models.
