The Transportation Research Board’s National Cooperative Highway Research Program
(NCHRP) Research Report 854: Guide for Identifying, Classifying, Evaluating, and Mitigating
Truck Freight Bottlenecks provides transportation agencies state-of-the-practice information on
truck freight bottlenecks using truck probe data rather than traditional travel demand models.
The report embraces a broad definition of truck freight bottlenecks as any condition that acts
as an impediment to efficient truck travel, whether the bottleneck is caused by infrastructure
shortcomings, regulations, weather, or special events. The comprehensive classification of
truck freight bottleneck types described in this report provides a standard approach for state
departments of transportation, metropolitan planning organizations, and other practitioners to
define truck freight bottlenecks and quantify their impacts.
