Congestion means the level at which transportation system performance is unacceptable due to excessive travel times and delays. Congestion management means the application of strategies to improve system performance and reliability by reducing the adverse impacts of congestion on the movement of people and goods in a region. - 10/10/2008

The primary purpose of an HOV lane is to increase the total number of people moved through a congested corridor by offering two kinds of incentives: a savings in travel time and a reliable and predictable travel time. Because HOV lanes carry vehicles with a higher number of occupants, they may move significantly more people during congested periods, even when the number of vehicles that use the HOV lane is lower than on the adjoining general-purpose lanes. In general, carpoolers, vanpoolers, and transit users are the primary beneficiaries of HOV lanes. - 8/25/2008

Definition: "Transportation System Management and Operations" {23 U.S. Code 101(a)(39), HR1195} is (A) IN GENERAL - The term "transportation systems management and operations" means an integrated program to optimize the performance of existing infrastructure through the implementation of multimodal and intermodal, cross-jurisdictional systems, services, and projects designed to preserve capacity and improve security safety, and reliability of the transportation system. (B) INCLUSIONS - The term "transportation systems management and operations "includes - (i) regional operations collaboration and coordination activities between transportation and public safety agencies; and (ii) improvements to the transportation system, such as traffic detection and surveillance, arterial management, freeway management, demand management, work zone management, emergency management, electronic toll collection, automated enforcement, traffic incident management, roadway weather management, traveler information services, commercial vehicle operations, traffic control, freight management, and coordination of highway, rail, transit, bicycle, and pedestrian operations. - 7/28/2008

The Freight Facts and Figures 2007 report is a snapshot of the volume and value of freight flows in the United States, the physical network over which freight moves, the economic conditions that generate freight movements, the industry that carries freight, and the safety, energy, and environmental implications of freight transportation. This snapshot helps decision makers, planners, and the public understand the magnitude and importance of freight transportation in the economy. (Publication Number: FHWA-HOP-08-004) - 2/27/2008

When planned special events are held, they generally increase traffic demands in or near the location of the event. In order to address this influx of traffic, transportation management plans are developed with the intent of minimizing the effect the event has on the transportation system. For a transportation management plan to be successful, however, it is strongly recommended that the plan be tested and reviewed prior to the event. One of the most effective ways to test a transportation management plan is through a tabletop exercise.

The Localized Bottleneck Reduction (LBR) program is focused on recurring congestion chokepoints (as opposed to nonrecurring congestion problems) and the operational influences that cause them. Operational influences are the highway junction and decision points (e.g., lane drops, weaves, on- and off ramps, signals, intersections, merges, tollbooths, width-restricted underpasses, etc.) that can become overwhelmed by vehicle volume on a recurring basis.
