ITS Deployment Analysis System (IDAS)

The ITS Deployment Analysis System (IDAS) is software developed by the FHWA that can be used in planning for Intelligent Transportation System (ITS) deployments. State, regional, and local planners can use IDAS to estimate the benefits and costs of ITS investments – which are either alternatives to or enhancements of traditional highway and transit infrastructure. IDAS can currently predict relative costs and benefits for more than 60 types of ITS investments. Practitioners will find a number of useful features that enhance ITS planning. For example, IDAS:

  • Works with the output of existing transportation planning models;
  • Compares and screens ITS deployment alternatives;
  • Estimates the impacts and traveler responses to ITS;
  • Develops inventories of ITS equipment needed for proposed deployments and identifies cost sharing opportunities;
  • Estimates life-cycle costs including capital and O&M costs for the public and private sectors;
  • Provides documentation for transition into design and implementation.

The IDAS software may be purchased through the McTrans Center.
