Report on the 2022 Western States Forum
The 2022 Forum was held on June 14 – 16 in Yreka, California. The event featured eight technical presentations and provided a variety of networking and discussion opportunities. A total of 45 participants joined. These attendees represented nine states (AZ, CA, IA, MT, NV, OR, TX, UT, and WA), five state DOTs, four universities, and the Southwest Research Institute. Caltrans Headquarters and Traffic Operations, Caltrans DRISI, and five of the twelve Caltrans transportation districts also participated. Overall, the Forum received positive feedback, with attendees stating that it is “one of the best conferences for us to attend.”

The Forum provides in-depth presentations that address rural ITS projects. Presentations run from 90 minutes to two hours and include time for questions, answers, and discussion. Detailed information about this year’s presentations is located on the 2022 Forum Page on the Forum’s website.
The Forum began with a presentation by Keith Koeppen from Caltrans District 2. Keith’s presentation addressed efforts to mitigate weather impacts on Interstate 5 in Northern California. In order to reduce traffic queuing caused by winter road conditions and driving restrictions, Caltrans District 2 developed a changeable message sign (CMS), blank out sign (BOS), and Lane Control Sign (LCS) system. Keith provided an analysis of the system as well as a background of the problem and discussion of challenges encountered during the project.

Troy Torgersen presented on the implementation of a Variable Speed Limit (VSL) system along the I-15 corridor in rural Utah. He discussed the design of the VSL algorithm and provided a description of the equipment necessary for its fully autonomous operation. His presentation concluded with a review of lessons learned in relation to VSL system materials, equipment, placement, and construction.

Iowa State University Research Engineer, Skylar Knickerbocker, described a Dynamic Message Sign system deployed by the Minnesota DOT to alert drivers of winter road conditions. He then discussed his project that analyzed driver behavior when advisory messages triggered by pavement sensors were displayed on DMSs. Methodology, data analysis, results, potential benefits and next steps were all part of the presentation.

LaShonn Ford presented on the Nevada DOT’s adoption of the Transportation Systems Management and Operations (TSMO) strategy. TSMO addresses challenges with the use of systems management and operations rather than the traditional capacity building project approach. LaShonn described specific TSMO strategies and explained the NDOT project components, progress, and next steps. He concluded with a summary of challenges faced and lessons learned.

Justin Belk and Joshua Hudson discussed the Washington State DOT’s development and integration of a Work Zone Data Exchange (WZDx). The presentation began with a background on WZDx activity and importance and continued into a discussion of work zone technology and associated data efforts, project scope, and system goals. Justin and Joshua demonstrated features of the work zone data base and a Pi-Lit set-up populating the work zone data feed. They finished the presentation with a summary of lessons learned.

Troy Torgersen provided an update on the Utah DOT’s 2019 presentation, which had analyzed four Rural Intersection Conflict Warning Systems (RICWS) that were deployed to reduce car crashes. Troy then described Utah’s new, less expensive approach to implementing conflict warning systems, which allowed the state to install ten new systems for the same total cost as the original four.

Dan Rossiter from the Southwest Research Institute presented on the usage of commodity traffic cameras as an alternative to traditional roadway sensors. He described improvements in machine learning capabilities and computer vision technology and their potential impact on sensing equipment usage. Dan explained that with the introduction of new software, agencies could utilize existing traffic cameras to provide the benefits of traditional sensing equipment at a much lower cost.

Eric MacGill and Jeffrey Bickett presented on the application of fiber optic sensing technology to traffic monitoring efforts. Eric and Jeff explained how distributed acoustic sensing uses unused fiber optic cable to detect traffic on roadways, and described the ability of this technology to predict traffic speed and queuing rates. They then provided details on their current project, which uses fiber optic technology to obtain data along I-15 and I-95 in Las Vegas, Nevada.

The Western States Forum is committed to providing networking opportunities as well as technical presentations. These opportunities allow participants to meet one another, share ideas, and maintain the informal and transparent nature of the Forum. In the image below, attendees gather and talk during the no-host reception before the Tuesday evening dinner.

The Western States Forum is organized and facilitated by a Steering Committee. This Committee chooses abstracts, reviews presentations, and plans the logistics associated with the event. Members of the Steering Committee include Leann Koon from the Western Transportation Institute (not present) as well as those in the image below. From left to right: Jeremiah Pearce, Caltrans District 2; Doug Galarus, Montana Tech; and Sean Campbell, Caltrans Division of Research, Innovation, and System Information (DRISI).
