This definition encompasses a wide range of events and conditions, all of which add time to the delivery of truck freight shipments, from the time those shipments leave their origin to the time they arrive at their destination.

4 Guide for Identifying, Classifying, Evaluating, and Mitigating Truck Freight Bottlenecks A separate cube would exist for each direction of travel for a given roadway. An initial step in the travel speed-based process is to conduct an analysis that defines the size and scope of the travel speed-based congestion bottleneck problem throughout a study area.

Both situations force trucks to travel addi tional miles, increasing the cost of freight delivery as a result of both additional labor hours and additional mileage driven.

Summary 7 bottlenecks, it is necessary to link the variables that describe potential bottleneck factors to the time and location data that describe vehicle volume and speed. The desktop analysis described above can be combined with field analysis to fully analyze select bottlenecks.

8 Guide for Identifying, Classifying, Evaluating, and mitigating Truck Freight Bottlenecks Finally, the Guidebook describes how truck bottleneck analysis can be incorporated into typi cal planning studies. The typical planning study is composed of existing and future conditions, identification of needs and solutions, analysis of solutions/recommendations, and outreach.
