18th Annual Western States Forum a Success

The Western States Rural Transportation Technology Implementers Forum(the Western States Forum or WSF) continued the tradition of success at its 18th annual event in June. Designed to share rural transportation solutions that have been deployed in the field, the Forum featured seven technical presentations and demonstrations and provided a variety of networking and discussion opportunities for state departments of transportation (DOTs) and local and public agencies. Its small size (a maximum of 50 participants), invite-only guest list, and absence of vendors kept presentations in-depth and discussion lively and open. The 2023 Forum had a full house, with 49 participants representing eight states (AZ, CA, MT, NV, OR, TX, UT, WA), and six DOTs, including all five of the Western States Rural Transportation Consortium (WSRTC) member states (CA, OR, NV, UT, WA).

The Forum design is unique; speakers submit two drafts of their presentation for review by a steering committee, which then provides detailed feedback. This review process helps maintain the level of technical detail which distinguishes WSF from other conferences. A day and a half are devoted to presentations, so speakers are given an extended amount of time to delve into the “nuts and bolts” of their project’s outcome, whether it relates to equations, source code, component-level discussion, or lessons learned. Forum participants are also encouraged to engage with speakers and discuss the material presented both during and at the end of each presentation.

This year’s agenda included presentations from California, Utah, Nevada, and Washington, each with their own unique topics and perspective. Presenters from Caltrans District 2 provided a detailed review of broadband communication design strategies for Intelligent Transportation System (ITS) applications and explored how the system architecture has evolved and expanded successfully. Speakers from Caltrans District 3 discussed a web application and server that interfaces with existing transportation management systems to send batches of CMS messages based on a message playbook. The presentation also demonstrated how other organizations could create similar applications. The Caltrans Office of Radio Communications brought over their satellite communications truck and trailer from District 1 and accompanied their presentation with a parking lot demonstration.

The Utah DOT Weather Operations group spoke on a topic new to the Forum: wildfire response and a process for analyzing wildfire burn severity and debris flow probability with the use of portable Road Weather Information System – Environmental Sensing Stations (ESS). Their presentation explained how the process and system provides automatic alerts to stakeholders to minimize the time required to clear the debris flow area and keep personnel safe. Washington State DOT discussed their experience testing and procuring a wrong-way vehicle detection system that accurately detects vehicles entering a highway from the wrong direction. They also described how that system integrates with current infrastructure to alert the TMC if a vehicle is confirmed to be driving in the wrong direction. Nevada DOT had a contingent of speakers who presented on two topics. The first discussed their newly implemented managed lighting control system, which enables real-time adjustments to roadway lighting levels, along with monitoring for maintenance. The second presentation described NDOT’s use of the 3-GIS network management software for telecommunications infrastructure and asset management.

WTI has coordinated the Forum since its inception in 2006. It is supported by the Western States Rural Transportation Consortium, a transportation pooled fund consisting of five Western states – California, Oregon, Nevada, Utah, and Washington (lead state). Over the years, the Forum has hosted more than 650 participants, with nearly 300 individuals from 14 different states. The 2023 forum was joined by 22 first-time participants and nine “regulars” who have attended 11 or more events.

The WSF has been established as an excellent means of disseminating information on Rural ITS among designers, engineers, and maintainers. It has also resulted in many examples of projects that were inspired by, or built upon, past WSF presentations. Sharing lessons learned (positive or otherwise) only advances the state of practice.

Information about the 2024 event will be posted this fall.

David Kack Hands WTI Director Role to Kelvin Wang

Two men smile and shake hands.A word from our staff:

As Montana State University prepares for the start of the Fall semester, August is also bringing change to WTI as we welcome a new director. As many of you may know, David Kack and his family have started a new life chapter in Tennessee, and while David will continue remotely as WTI’s Program Manager for the Mobility & Public Transportation group and as the Director of the Small Urban, Rural and Tribal Center on Mobility (SURTCOM), he is handing over the role of WTI Director here in Bozeman. David joined WTI as a researcher in 2002 and his many years of experience and institutional knowledge earned him the position of Director when long time WTI leader, Steve Albert, retired in 2019. David’s tenure was anything but business as usual. Within his first year he was immersed in emergency response management as the coronavirus shutdown began. During this time, David continued research and director responsibilities, but also sanitized our offices and common areas on a regular basis, motivated us through clever communications as we adjusted to working remotely, and welcomed us all back when the coast was clear – well, sort of clear. Most memorably, he managed and hosted the twice rescheduled (due to the pandemic) Council of University of Transportation Centers (CUTC) Summer Meeting in Big Sky during a new COVID surge in 2022 that coincided with an epic 100-year flood on the Yellowstone River, stranding Summer Meeting participants in airports and flooded areas. His signature calm, humor, and level headedness prevailed and executed a successful and very memorable Summer Meeting. While his accomplishments and contributions to WTI and the Gallatin Valley are too numerous to cover here, we extend huge thanks and appreciation to David for his dedication as Executive Director over the last four years.

David Kack is handing over the role of director as his family starts a new chapter out of state. He has led WTI since 2019 and has guided WTI through Covid-19, the transition to work-from-home, and bringing everyone safely back to the office. David will continue in his role as Program Manager for the Mobility & Public Transportation group, as well as the Director of the Small Urban, Rural and tribal Center on Mobility (SURTCOM). Thank you, David, for you dedication to WTI and leadership!

Dr. Kelvin Wang has been named the new WTI Director as of August 1st. Please join us in welcoming Director Wang to Bozeman and WTI. Find the MSU announcement here: https://www.montana.edu/news/23004/kelvin-wang-named-director-of-msu-s-western-transportation-institute

From David: On Merging and Passing

I’ve noticed that merging into traffic is often accompanied by a feeling of anxiety. We get up to speed at an interstate onramp or to pass a vehicle, especially a big truck, and feel the need to pay a bit more attention to what we are doing. This is how the month of August will feel for me, and for the next Director of WTI, Dr. Kelvin C.P. Wang, who officially began his new role August 1.

I merged my professional life with WTI back in 2001 when I started as a half-time employee. I was fortunate to work on many different projects with an array of co-workers. At the time, I was only the third non-engineer that was working at WTI. I quickly became a full-time employee, then became the Program Manager for our Mobility & Public Transportation research area, and then the Director of the Small Urban and Rural Livability Center (a Tier 1 UTC) under MAP-21. In 2019, I was named the Interim Director of WTI when our long-time director, Steve Albert, retired. The “Interim” tag was removed in 2020 and it has been an honor and privilege to lead an amazing group of people at WTI these past four years.

Now, however, I am passing on the title and responsibilities of Director to Kelvin, who is moving to Bozeman from Stillwater, Oklahoma and has decades of experience as university faculty and four years as a DOT engineer. I will continue my role at WTI as Program Manager for Mobility & Public Transportation, as well as fulfilling my role as Director of the Small Urban, Rural and Tribal Center on Mobility (SURTCOM), our Tier 1 University Transportation Center (UTC) funded through the FAST Act.

Though the title on my business cards and emails is changing, my dedication to WTI and the transportation profession remains as strong as ever. Kelvin and I will pay a bit more attention during the month of August, as he merges his professional career with WTI, and I pass the Director role to him.

May all your personal and transportation-related mergers and passes go smoothly!

From Kelvin:

I am honored and grateful to be the new director of WTI. Since mid-June, I’ve been familiarizing myself with the operations of WTI and its relationships with various entities at MSU and the Montana Department of Transportation (MDT). I would like to thank Mr. David Kack for his expertise and unreserved support during our transition in roles.

Based on what I’ve learned, I can say that the future of WTI is bright, and we have enormous opportunities to grow in the coming years. I will provide a more detailed plan in September outlining our potential expansion. Thank you all for your hard work in the last decades to make WTI a national and international leader in transportation research! Together we will open a new chapter at WTI, where we will continue to provide high-impact research solutions to the state, the nation, and our international partners. I am excited for what is to come.

Dr. Kelvin Wang, Director
