System Efficiency: Extent of Congestion

The intent is to manage the proportion of the transportation system that experiences recurring congestion (the spatial extent of congestion). 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.

Associated Objectives and Performance Measures

Objective	Performance Measure
Reduce the percentage of facility miles (highway, arterial, rail, etc.) experiencing recurring congestion during the peak period by X percent by year Y.	Percent of lane-miles (or rail) operating at LOS F or V/C > 1.0
Maintain the rate of growth in facility miles experiencing recurring congestion as less than the population growth rate (or employment growth rate).	Percent of lane-miles (or rail) operating at LOS F or V/C > 1.0
Reduce the share of major intersections operating at LOS Z by X percent by year Y.	Percent of intersections operating at LOS F or V/C > 1.0

Associated Planning Factors and Goals

Planning Factor	Goal
G. Promote efficient system management and operation;	Improve the efficiency of the surface transportation system
