TREDIS is designed to recognize the unique issues faced by each step or sequence in the transportation planning process.  Its input forms and output reports are tailored to meet those needs ...from long-range plans to project selection, alternatives analysis and asset management.  

Using the assisted mode, the system will query the user regarding the type of problem and audience, and then tailor its input needs and result outputs to match that situation.  This makes TREDIS easy to use by transportation planners...without requiring a PhD in economics!

 Hover on each stage in the graphic to see key aspects of TREDIS applicable for it.

TREDIS also maintains its expert mode, allowing the user to have complete control over their analysis inputs and results.
