Transportation Economic Development Impact System
Encyclopedia
Transportation Economic Development Impact System(TREDIS) is a web-based analysis system that is used in planning major transportation investments in the US and Canada. The role of economic impact analysis
and TREDIS in the transportation planning
process is explained in guidebooks of the US Department of Transportation and American Association of State Highway and Transportation Officials
.
TREDIS has been most commonly used for assessing the expected economic impacts of statewide highway
programs, regional multi-modal
plans and public transport
investment. Its history and theoretical foundation is explained in peer reviewed journal articles.

Highway
A highway is any public road. In American English, the term is common and almost always designates major roads. In British English, the term designates any road open to the public. Any interconnected set of highways can be variously referred to as a "highway system", a "highway network", or a...

Intermodal passenger transport
Intermodal passenger transport involves more than one mode of transport of passengers. Some modes of transportation have always been intermodal; for example, most major airports have extensive facilities for automobile parking and have good rail or bus connections to the cities nearby. Urban bus...

How It Works
TREDIS has a series of modules that calculate different forms of impacts and benefits. One module is an accounting framework that calculates user benefits, including impacts on cargoCargo
Cargo is goods or produce transported, generally for commercial gain, by ship, aircraft, train, van or truck. In modern times, containers are used in most intermodal long-haul cargo transport.-Marine:...

Commuting
Commuting is regular travel between one's place of residence and place of work or full time study. It sometimes refers to any regular or often repeated traveling between locations when not work related.- History :...
cost, based on transportation forecasting
Transportation forecasting
Transportation forecasting is the process of estimating the number of vehicles or people that will use a specific transportation facility in the future. For instance, a forecast may estimate the number of vehicles on a planned road or bridge, the ridership on a railway line, the number of...

Gross Regional Product
A metropolitan area's gross regional product, i.e. GMP or GRP, is one of several measures of the size of its economy. Similar to GDP, GRP is defined as the market value of all final goods and services produced within a metropolitan area in a given period of time.-See also:*List of European...
