A New Concept
For those of you who are new to TREDIS, here is a brief overview.
The Transportation Economic Development Impact System is a new analysis concept - a modular framework for evaluating economic development impacts and conducting benefit cost analysis for freight and passenger rail, marine, air and road transportation projects and policies.

Uses of TREDIS
TREDIS aids state, region and local level transportation planning, project prioritizing, freight policy, toll policy and EIS reports.
It enables evaluation of project and program impacts on multimodal transport access, connectivity, intermodal interactions and their economic impacts at a detailed level.
Even if you already have an economic model such as REMI and/or a statewide project planning and assessment system, you will find that the TREDIS framework can bring substantial added value to it.
TREDIS works in both the US and Canada.

What TREDIS Provides
(1) a set of economic impact and benefit-cost analysis tools that can be used together or separately,
(2) a web-based system enabling collaboration among people at different locations and agencies,
(3) a valuable reporting system enabling measurement of impacts, benefits and costs from different perspectives,
(4) an award-winning business attraction assessment enabling support for local economic developers, and
(5) an ability to extend economic impact analysis to both freight and passenger elements of rail, air, marine, road and intermodal facilities.

| Initial Applications of TREDIS
We've been
evaluating user experience with the TREDIS system for over two years. The model has successfully contributed to the following projects:
- Enhancing applications of the REMI model at WisDOT and
MaineDOT.
- Assessing congestion reduction and multimodal impacts in Portland,
OR and Vancouver,
BC.
- Gauging high speed trains and commuter rail service proposals
in California, Illinois
and Alberta.
- Evaluating proposed changes in short-line freight rail in Wisconsin.
- Examining the economic implications of the Chicago
freight plan.
- Investigating long-range plans for MaineDOT's multimodal system and Oregon's highway
system.
These cases range in
complexity from simple sketch planning spreadsheets to complex multi-modal
modeling. You can read about these
cases on the EDR Group website and print out reports and reviews from each case.

Featured Case: Oregon Statewide Plan
The Oregon Business Council, working together with Oregon DOT, conducted a study of how highway system bottlenecks are growing over time, and their effects on passenger and freight movements. ODOT studied access to various rail, marine, and air terminals, as well as access to tourism centers and major trade corridors. ODOT staff applied their Gen1/TRANUS transportation and land use modeling system - which was then used with TREDIS to estimate how changes in transportation access, connectivity and reliability will lead to further economic development. Policy implications of these results generated significant interest by the press and legislators.

Webcasts, Conference Display and Website Update
Having taken the care and time needed to test and demonstrate the usefulness of TREDIS, the system is now being rolled out for broader use around North America in the following sequence.
