System Efficiency: Duration of Congestion (Objective Category)

These objectives focus on managing the duration of recurring congestion (roadway or intersection) on the transportation system. The duration of recurring congestion represents the length of time that a facility is congested. Common expressions of recurring congestion are volume-to-capacity (V/C) ratio and level of service (LOS), which is measured in terms of travel speed or delay. In areas where there is extensive congestion, the degree or intensity of congestion can be revealed, particularly for areas that experience significant congestion (spatially and/or temporally).

Associated Objectives and Performance Measures

Objective Performance Measure
Reduce the daily hours of recurring congestion on major freeways from X to Y by year Z. Hours per day at LOS F or V/C > 1.0 (or other threshold).
Reduce the number of hours per day that the top 20 most congested roadways experience recurring congestion by X percent by year Y. Hours per day at LOS F or V/C > 1.0 (or other threshold).

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.
