On July 14, 2016, the NOCoE hosted a Webinar on the practice of Part-Time Shoulder Use. The Webinar provided an overview of the recently published FHWA Part-Time Shoulder Use Guidebook, and peer state program examples from the Virginia  and Colorado DOT. The panelist for the webinar included the following:

  • Jim Hunt, FHWA Office of Operations
  • Pete Jenior, Kittelson & Associates, Inc.
  • Dean Gustafson, VDOT, State Operations Engineer
  • Ryan Rice, CDOT, Director of the Division of TSM&O
  • San Lee, CDOT, TSM&O Programs and Policy Manager

This discussion thread was started to help facilitate further questions and conversation on the information presented by the panelist. So far the following questions have been submitted:

  1. To All:  What is the most common criteria for activating dynamic shoulder use?
  2. To VDOT: Do you get a lot of vehicles riding in the shoulder lane when the red X is displaying on the dynamic sign?
  3. To CDOT: Was your I-70 traffic analysis only for Sunday, which was able to trigger the value in initiating project development?
  4. To All:Why has different pavement been discouraged if it seems to be advantageous?
  5. To All: Since First responders normally rely on the shoulder to expedite their access to traffic incidents, what accommodations might be made for them if a shoulder is not available because it is being used as a live traffic lane?
  6. To CDOT:  I understand the Hard SHoulder Running project was tied to a reversible lane. The improvement charts and figures that you should indicate improvement only for Hard SHoulder Running implementation or for that combined with the reversible lane?
  7. To All: Any guidance on use of shoulders as a truck passing or climbing lane, especially when traffic volumes and truck traffic percentages are high?

Regarding Question 5 on First Responders, there are a couple of facets to this issue:

  1. Collaboration with police and other emergency responders is fundamental to success.

  2. Emergency turn off areas should be installed, ideally every half mile or so.

  3. Under and ATM scenario, the ability to close the shoulder lane and merge traffic into the GP lanes could mitigate the response challenges.

  4. If all else fails, EM vehicles will split the traffic or in some cases may respond from the opposite direction.

  5. To the extent that part-time shoulder use smooths flow and crashes can be reduced, it might make things overall better from a response standpoint.

Regarding question 6 on colored pavement, currently the MUTCD recognizes colored pavement in a couple of instances (e.g. Green for bike lanes and Red for bus lanes that are open to buses full time). There is no designated color for part time shoulder use and using any plan to use colored pavement would require a request to experiment.

Regarding the question on truck climbing/passing lanes:

We are aware of several instances of states allowing slow-moving trucks to use shoulders on long grades, but use is typically permitted at all hours of the day so it is not “part-time”
