Traffic Forecasting Accuracy Assessment Research
Accurate traffic forecasts for highway planning and design help ensure that public dollars are
spent wisely. Forecasts inform discussions about whether, when, how, and where to invest public
resources to manage traffic flow, widen and remodel existing facilities, and where to locate, align, and
how to size new ones.
The TRB National Cooperative Highway Research Program's
NCHRP Report 934: Traffic Forecasting Accuracy Assessment Research seeks to develop a process and methods by which to analyze and improve the accuracy, reliability,
and utility of project-level traffic forecasts.
The report also includes tools for engineers and planners who are
involved in generating traffic forecasts, including:
Quantile Regression Models,
a Traffic Accuracy Assessment,
a Forecast Archive Annotated Outline, a
Deep Dive Annotated Outline, and
Deep Dive Assessment Tables,
