Vermont Travel Study Featured in TRB Newsletter

The National Academy of Sciences Transportation Research Board (TRB) is raising awareness of a new WTI study on travel behavior, by highlighting it in its weekly newsletter.

Researchers Andrea Hamre and Jonathan Fisher recently completed “Travel Behavior and Transportation Planning Insights from the Small Urban Area of Chittenden County, Vermont: An Application of Traveler Segmentation,” sponsored by the Small Urban, Rural, and Tribal Center on Mobility (SURTCOM).  The primary purpose of this project was to analyze transportation planning and travel behavior of County residents, using data from four travel surveys conducted over the last 20 years.

The survey series collected information from respondents about travel preferences and priorities for regional transportation investments. The research team applied traveler segmentation to classify the survey sample into three modal orientations — Alternative [transportation] Oriented, Car Tolerant, and Car Oriented.

According to the team’s analysis, nearly half (49%) of the respondents fell within the Car Tolerant segment. These respondents use their cars frequently, but also show a high willingness to change their travel behavior, as well as strong support for incentives to use alternative transportation. The team also found that Chittenden County adults would like fewer resources devoted to highways than are currently being allocated, and that support for gas tax increases is higher for non-highway purposes than for use exclusive to highways. These findings may help Chittenden County officials prioritize future transportation investments and develop multi-modal systems that meet a range of public needs.

Transportation Research Board Highlights WTI’s Severe Weather Index Project

Bicyclist and car travel through neighborhood in heavy snow conditions

WTI has completed a project to create a severe weather index for the Maryland Department of Transportation, and the final report was featured in a recent issue of the National Academy of Sciences Transportation Research Board’s newsletter.

A severe weather index (SWI) is a management tool that  can be used to assess the performance and related costs associated with winter maintenance operations – it considers the relative severity of each weather event and the relative severity of weather for that season.  On behalf of the Maryland DOT State Highway Agency (MDOT SHA), WTI researchers Laura Fay, Natalie Villwock-Witte, and Karalyn Clouser, in partnership with David Veneziano of Iowa State University, developed and tested an SWI using Road Weather Information System (RWIS) data and input from maintenance managers. 

In addition to the development of the SWI itself, key outcomes of this effort include the identification of locations where blowing and drifting snow impacts the road network, the identification of future sites for RWIS stations, survey results describing RWIS use by MDOT SHA maintenance crews, and a detailed review of the RWIS network and data.  The final report also provides recommendations to MDOT SHA for improving the SWI and overall winter maintenance operations. “We’re pleased that MDOT SHA is evaluating the tool and plans to implement it in the 2020-21 winter season,” said P.I. Laura Fay; “The sooner it’s used and assessed during actual storm events, the sooner it can be calibrated and refined, which will improve its usefulness.”

New Publication: Safe Interactions Between Vehicles and Bicyclists

The Journal of Safety Research has published an article that examines the influence of traffic safety culture on a driver’s behavior when interacting with bicyclists on the roadway.

“Traffic safety culture and prosocial driver behavior for safer vehicle-bicyclist interactions” is based on a research collaboration between the Center for Health and Safety Culture (CHSC) and the Small Urban, Rural, and Tribal Center on Mobility (SURTCOM) at WTI.  Authors include CHSC researchers Nic Ward, Kari Finley and Jay Otto of CHSC, and David Kack, Rebecca Gleason, and Taylor Lonsdale of SURTCOM.

Bicyclist safety is a growing concern as more adults use this form of transportation for recreation, exercise, and mobility. Most bicyclist fatalities result from a crash with a vehicle, and the behaviors of the driver are often responsible for the crash.  The researchers conducted a survey study of Montana and North Dakota residents and found that prosocial driver behavior was most common and appeared to be intentional. They also found that this intention was increased by positive attitudes, normative perceptions, and perceived control. The findings can be used to develop strategies to increase prosocial intentions and driver behavior, thereby increasing bicyclist safety.

Rob Ament and Marcel Huijser, in collaboration with research partners at the engineering firm of WSP USA, led the research for “Valuing Wildlife Crossings and Enhancements for Mitigation Credits,” a project sponsored by the National Cooperative Highway Research Program (NCHRP), part of the National Academy of Sciences (NAS). Mitigation crediting could provide a valuation approach for state DOTs interested in promoting the construction of wildlife crossings and other enhancements to mitigate transportation project impacts.

The report includes extensive information collected from a survey of more than 200 state DOTs and natural resource agencies on valuation methods and mitigation credits that have been used by state DOTs and their partners, as well as potential methods and approaches that could be developed in the future.  The study also highlights four case studies of wildlife connectivity mitigation from California, Colorado, and Florida.

The report is available for download from the National Academies Press website. The American Association of Highway Transportation Officials (AASHTO) also highlighted the publication in its daily newsletter last week.

Cover image of Proactive Traffic Safety report with title and photo of children walking on a sidewalkTwo new traffic safety culture publications, drafted by Center for Health and Safety Culture (CHSC) researchers for the Montana Department of Transportation (MDT), have been featured in the last two national newsletters of the National Academies of Sciences Transportation Research Board (TRB).

Kari Finley, Jay Otto, Nic Ward and Jamie Arpin authored “Proactive Traffic Safety: Empowering Behaviors to Reach Our Shared Vision of Zero Deaths and Serious Injuries,” a primer that defines proactive traffic safety and offers strategies and examples of how agencies can integrate it into their own safety programs and initiatives. This resource includes specific tips and communication tools for working with stakeholders and conducting public education events.

 

Cover image of Traffic Safety Culture Primer report with title and image of a downtown streetFinley, Otto, and Ward also developed the “Traffic Safety Culture Primer,” which introduces the concept of traffic safety culture and how it influences road user behavior. It provides examples of how growing a positive traffic safety culture can be used to enhance safe behaviors around issues such as impaired driving and seat belt use within an organization or at the community level.

CHSC created both primers as part of the Traffic Safety Culture Pooled Fund program, for which MDT serves as the lead agency.  The primers and additional resources are available on the Proactive Traffic Safety webpage and the Traffic Safety Culture Primer webpage of the MDT website.

WTI Researchers Contribute Chapter to Mobility Workforce Book

Book Cover image showing child on scooter and book titleA newly published book on training the next generation of transportation workers at all levels includes a chapter written by two WTI staff members.  Empowering the New Mobility Workforce: Educating, Training, and Inspiring Future Transportation Professionals identifies strategies that education, industry, and government leaders can use to facilitate learning and skill development related to emerging transportation technologies and challenges. Susan Gallagher, WTI’s Education Workforce Program Manager, and former WTI Director, Steve Albert wrote a chapter on “Cultivating a rural lens: successful approaches to developing regional transportation corridors through professional capacity building,” which focuses on the unique workforce challenges faced by transportation agencies at the rural and regional level and describes relevant examples of incorporating professional capacity building into transportation projects.

The book addresses one of the most critical issues in transportation – the growing workforce shortage. Transportation industries project a need to hire more than 4 million employees over the next decade.  Empowering the New Mobility Workforce has been endorsed by national transportation leaders, including former U.S. Secretary of Transportation Norm Mineta. It is available on the Elsevier Publishing website or on Amazon.com.

Research Update – Are Wyoming Deer and Antelope Using Existing Underpasses to Cross Highways?

WTI is conducting a research on behalf of the Wyoming Game and Fish Department (WGFD) and the Wyoming Department of Transportation (WYDOT) to explore mitigation options for reducing wildlife vehicle collisions along Interstate 25 in central Wyoming.  WYDOT and WGFD would like to explore the possibility of funneling large mammals, particularly mule deer and pronghorn, through the existing underpasses on this section of road rather than building new ones specifically designed for wildlife.

As one of the research steps, project researchers Marcel Huijser, Amanda Warren, and Elizabeth Fairbank collected preliminary data on wildlife use of existing structures under I-25 which were not originally designed for wildlife. Based on an eight-month monitoring effort in 2018-2019, the research team found that the structures are predominantly used by mule deer and white-tailed deer, but almost never by pronghorn.  More details are available in the interim report (“Preliminary Data on Wildlife Use of Existing Structures along I-25, Kaycee, Wyoming, USA”), which was recently published and is available on the project page of the WTI website.
