Recurring Traffic Bottlenecks: A Primer

Mark P. Rossow, Ph.D, PE Retired

Although many of the nationís traffic bottlenecks must be addressed through costly major construction projects or expensive alternatives such as high-occupancy vehicle lanes, dynamic pricing, or transit alternatives, a significant opportunity exists for applying operational and low-cost solutions at spot-specific locations. This course is based on a primer produced by the Localized Bottleneck Reduction program of the Federal Highway Administration. The course focuses on relieving recurring congestion chokepoints (as opposed to nonrecurring congestion causes) and the operational influences that cause them. Widening, lengthening, retiming, metering, or bypassing problem areas to unclog them can often be done with lower cost and less intensive means than required by completely rebuilding the system. These options and other low cost alternatives are described in the course. Examples of how some state agencies are dealing with bottlenecks are given.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
