This project established a framework for the creation and maintenance of a statewide strategy for identifying, anticipating, and mitigating freight bottlenecks on interstate highways in the state of Alabama. It used methodology developed by Cambridge Systematics to identify and quantify bottlenecks. This research identified nine freight bottlenecks on Alabama interstates using 2006 traffic data supplied by ALDOT. These include six capacity bottlenecks, which are caused by an insufficient capacity in relation to demand (where the ratio of Average Annual Daily Traffic to the capacity of the roadway in passenger cars per hour per lane is greater than 8). The other three bottlenecks are interchange bottlenecks, which are similar to capacity bottlenecks except they occur at interchanges involving two or more interstates.
