STREAM Introduction 2 9 May 2013
• They face many obstacles, but not all of them are technical– Many technology alternatives; uncertainty over potential results– Most DOTs & MPOs are not well suited for technology assessment
• Internal culture; institutional barriers; information
– Agencies operate in complex public/private environment– “If you’ve seen one DOT… you’ve seen one DOT.”
• NCHRP: Need ways to evaluate technologies that– Are relevant to agency missions– Overcome barriers to technology adoption and inherent uncertainties– Can be more easily used and shared collaboratively by DOTs and MPOs
Transportation Agencies Appear to be Slow Adopters of Innovations

• How well will they help in practice?• How will they contribute to mission goals?• Will they work in our state?• How do they compare to current practice?• What changes do they require?• How difficult are they to implement?• What do they cost? How are costs distributed?
Who pays?• How long will they last?• How flexible can we be?
Is There a Way to Compare Apples and Oranges…

STREAM Introduction 27 9 May 2013
STREAM Assists Not Just Individual Agencies
• Establishes common vocabulary• Incorporates and diffuses best practice• Allows easier sharing & application of results• Provides basis for formal collaboration to share effort
― First four steps can be carried out jointly― Last three steps tuned to individual conditions― Assumptions and inputs to analysis are explicit
and may be changed to suit local circumstances
