New Project: Safety Improvements for Low-Volume Roads in Montana

Highway agencies systemically screen the road network to identify those sites that are expected to yield the greatest safety benefits from an investment of available improvement funds.  Traditional methods for identifying candidate locations tend to focus on well-travelled roadways that experience higher crash frequencies, despite the fact that many low-volume roads may have high levels of risk due to their geometric and roadside features (e.g. curves, low visibility). Further, many of the crashes on remote local roads, particularly those with lower severities, may go unreported.

On behalf of the Montana Department of Transportation (MDT), WTI will develop a methodology for identifying and prioritizing hazardous locations on local roads at the network level that are deserving of safety improvement funds. Another objective is to engage Montana counties to work closely with MDT on the development of both the methodology and future safety improvement projects.  This project will provide MDT with guidance for its safety improvement programs, enhance its outreach efforts to local agencies, and support its Vision Zero safety initiatives.

Register by May 15 to take advantage of the reduced Early Bird rate.  WTI is the local host for this conference, so please help spread the word to colleagues in your network.

The conference will provide a global forum to examine new technologies and new techniques in the planning, design, construction, operation, and maintenance of low-volume roads. Panelists will explore case studies and practical solutions to common problems related to all aspects of low-volume roads.

NEW PROJECT: WTI to Create a Guidebook for Transportation Agencies on Unpaved Roads

The guidebook will aid agencies in making effective decisions regarding conversion of paved roads to unpaved.

For roads with very low traffic volumes, some transportation agencies have found that that these roadways can be maintained more economically and at a higher level of service with an unpaved or granular surface, as compared with attempting to maintain an old paved surface. Through this project, WTI will develop a comprehensive information resource on effective practices for converting severely distressed paved roads to acceptable unpaved surfaces. The guide will be developed based on needs identified in a previous WTI project, NCHRP Synthesis 485 Converting Paved Roads to Unpaved.

Laura Fay, who led the NCHRP Synthesis, will also serve as Principal Investigator for this effort. The main benefit of this project will be the availability of an easy to use guidance document for agencies that operate and maintain low volume roads. The guide will help agencies select candidate roads for conversion, conduct more effective and safer conversions, and communicate with the public on how and why a conversion is taking place.

Additional project information is available on the project page of the WTI website.

To Pave or Not to Pave?

Dates Announced for International Conference on Low Volume Roads

WTI will host the 12th Transportation Research Board (TRB) International Conference on Low Volume Roads on September 15-18, 2019 in Kalispell, Montana. Sponsored by TRB, this conference examines new technologies and new techniques in the planning, design, construction, operation, maintenance, and administration of low-volume roads. Panelists will explore case studies and practical solutions to common problems related to all aspects of low-volume roads.  TRB, which is part of the National Academy of Sciences, announced the dates in its November 20 newsletter. For more information, contact Laura Fay at WTI or Nancy Whiting (nwhiting@nas.edu) at TRB.

Update:

We have created a Facebook group for family and guests of attendees in order to share information about activities in the area. Feel free to request to join the group.
