The Guidelines for Defining and Measuring Urban Congestion
assist practitioners and researchers define, measure, and monitor traffic
congestion in urban areas. The Guidelines provide directions on quantifying
traffic congestion for both urban freeway and arterial corridors, and are
applicable for motorized roadway transportation, including public transit mixed
with other motorized modes of transportation. They identify a range of
performance metrics to measure and monitor traffic congestion. 29 common congestion
measures were identified and categorized, in order to develop an objective
procedure that would assess and compare congestion.
The Guidelines are based on both findings from published
literature and results from a survey of Canadian and international
municipalities with experience in measuring traffic congestion in urban areas.
Background: Traffic congestion has become a major challenge
in most urban areas. In recent years, the development of measures to mitigate
traffic congestion has become a priority for many road agencies. To this end,
identifying congestion characteristics is an essential step in selecting
appropriate mitigating measures. E-books are NOT PDFs, but are accessed by web
