Overview
This Primer is the signature product of the Localized Bottleneck Reduction (LBR) Program, which is administered out of the Office of Operations, Office of Transportation Management, at FHWA HQ in Washington, D.C. This is the updated 3rd version of this document. The LBR program is focused on relieving recurring congestion chokepoints (as opposed to nonrecurring congestion causes) and the operational influences that cause them. Widening, lengthening, retiming, metering, or bypassing these problem areas to unclog them can often be done with lower cost, less intensive “footprint” means than traditionally waiting for a complete facility rebuild or an out-year project.
