Part-time Shoulder Use
Part-time shoulder use is the conversion of shoulders to travel lanes during some hours of day as a congestion relief
strategy. This strategy is also known as temporary shoulder use or hard shoulder running, and is typically implemented
on freeways. Part-time shoulder use is a transportation system management and operations (TSMO) strategy that uses
shoulders to provide additional capacity when it is most needed, and preserves shoulders as refuge areas during the
majority of the day. It may be bus-only, static (open to most vehicles, but fixed hours of operation), or dynamic (open to
most vehicles with variable hours of operation). In 2016, FHWA released a guide on Part-time Shoulder Use. This
presentation will cover planning, traffic analysis, safety effects, environmental analysis and regulatory issues, design,
implementation, and day-to-day operation of part-time shoulder use as it is described in the FHWA Guide. Case studies
of noteworthy facilities around the country will be shown. This presentation will also describe existing and planned part-
time shoulder use projects in Ohio.
Dynamic Hard Shoulder Running - Lessons Learned from the US and UK Experience
In the United States, there is a continuing effort to reduce traffic congestion through innovative and technology
supported approaches. Due to its lower cost than traditional road widening, hard shoulder running is increasingly being
seen as an attractive approach to increasing highway capacity and smoothing traffic flows. Common approaches include
simple fixed hour operations that use static signing, to more complex operations that use dynamic signs to add flexibility
to the hours of operations, usage requirements, and dissemination of additional information. Design considerations on
typical US HSR schemes include surveillance and monitoring of the HSR to identity debris and stalled vehicles, as well as
the need for emergency pullouts for disabled vehicles. Over the past several years, the number of US deployments has
increased to the point where a broad base of experience and lessons learned has started to emerge. The recent design
and implementation of HSR on Washington State I-405, for which the authors were involved, will serve as an example.
In the UK, hard shoulder running dates from 2006. After this initial deployment, Highways England embarked on an
ambitious program of HSR deployments. This included various revisions to the hard shoulder running design guidance,
introducing both minor and more fundamental changes to how hard shoulder running was implemented and operated.
This presentation will focus on the lessons learned from the US and UK experiences. The results will be presented within a
US context, specifically in relation to the dynamic nature of hard shoulder running within the US as opposed to the mix of
hard shoulder running and all lane running that is prevalent in the UK.
IR 670 Hard Should Running Implementation
ODOT is implementing a pilot project to create a hard shoulder running application on IR 670 EB from downtown
Columbus out to IR 270, the first application of this configuration in the state. The presentation will consist of a project
overview and provide answers to frequently asked questions.
