Evaluation of interstate highway capacity for short-term work zone lane closures
WA Sarasua, WJ Davis, DB Clarke… - Transportation …, 2004 - journals.sagepub.com
The need to maintain adequate traffic flow through short-term Interstate work zones is
paramount on today's heavily traveled freeways. Numerous states have policies related to
traffic flow thresholds, vehicle delay, and vehicle queue lengths that provide guidance on
conditions when shortterm lane closures can be instituted. Generally, traffic flow threshold
limits are a function of traffic-stream characteristics, highway geometry, work zone location,
type of construction activities, and work zone configuration. A research study was initiated in …

Estimating interstate highway capacity for short-term work zone lane closures: development of methodology
WA Sarasua, WJ Davis… - Transportation …, 2006 - journals.sagepub.com
Defining and understanding traffic flow parameters within short-term Interstate work zones
are crucial in developing effective policies to manage construction and maintenance work
conducted on the nation's heavily traveled freeways. The South Carolina Department of
Transportation (DOT) initiated a research study to develop a methodology for use in
determining an updated lane closure policy for Interstate highway work zones. Phase 1 of
the research was completed in May 2003, and findings identified threshold volumes for two …
