This Guidebook provides state-of-the-practice information to transportation professionals on identifying, classifying, evaluating, and mitigating truck bottlenecks. The bottleneck analysis described in this Guidebook is focused on utilizing truck probe data rather than traditional travel demand models. The primary application for the methodologies is evaluation of truck bottlenecks for prioritizing investment decisions.
This Guidebook serves the following purposes:
- Defines a common language related to truck freight bottlenecks;
- Classifies truck freight bottleneck categories based on causal and contributing factors;
