Because transportation investment programs have extended time horizons, state departments of transportation (DOTs) must forecast costs well into the future. This poses a serious challenge: the longer the time horizon, the more uncertainty and risk that forecasted costs will vary from actual, future costs.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 953: Improving Mid-Term, Intermediate, and Long-Range Cost Forecasting: Guidebook for State Transportation Agencies presents a cost forecasting method for use by state transportation agencies that better accounts for cost variability and economic volatility over time.

Supplemental information to the report includes NCHRP Web-Only Document 283: Improving Mid-Term, Intermediate, and Long-Range Cost Forecasting for State Transportation Agencies, a cost forecasting toolkit, a guidebook presentation, and videos.
