WSDOT produces technically rigorous performance analysis of its major programs. However, current reporting formats emphasize analytical completeness over the ability of users to comprehend the information and may limit legislative receptivity for investments such as preservation and maintenance. Washington State Executive Order 25-06 directs state agencies to modernize communication and improve customer experience. To aid WSDOT in meeting that goal, this project will pilot a research-based, human-centered design (HCD) framework for reporting on the state’s transportation system health (TSH) that will improve information clarity, accessibility, and decision impact while preserving analytical rigor. To explore how TSH performance reporting can be communicated more effectively through HCD principles, the researchers will interview end users and collaborate with subject matter experts to understand how different audiences—such as legislators, WSDOT executives, stakeholders, and the public—interpret and use performance information. Based on collected insights, the project will develop and test visualization and reporting approaches that present TSH information in formats that resonate with various audiences and is more useful for decision-making while also maintaining analytical rigor.

By 2050, the population of the central Puget Sound region is expected to grow by 1.5 million people to a total of 5.8 million. This project will evaluate several scenarios to illustrate how decisions about major transportation infrastructure investments and land use related to housing could affect the region by 2050. The researchers will look at the potential effects on the Puget Sound regional transportation system of major infrastructure investments that have either been identified or are in the early development stages. These include a third Puget Sound airport to complement SeaTac and Paine Field, I-5 lane expansion, ultra-high-speed rail from Oregon to British Columbia, and Amtrak Cascades passenger rail. They will also look at the effects of existing and potential housing zoning densities in Washington counties along the I-5 corridor. Scenarios will include evaluation of the travel times and costs for households and freight, as well as passenger air travel demand, cost, and availability. A holistic picture is needed for decision-makers to understand the tradeoffs and considerations for the future of Cascadia mobility. The results will provide decision makers and the public with a high-level understanding of major transportation needs and choices for the area’s 2050 population.

More information

Analysis of electronic transit farecard data can provide insight into how travelers use the system and how their behavior changes as both the urban form and transit services change over time. It can be used to answer a variety of policy questions, ranging from the impacts of adopted policies on transit use, to the quantity and quality of trips taken, to the differences in transit services provided to neighborhoods of different income levels to determine the equity of transit services provided throughout the region.  The Next Generation One Regional Card for All (NG ORCA) effort includes the development and deployment of a database system called DARe (Data Access and Reporting), which is being used to collect, manage, and store data on the use of ORCA cards and accounts. However, to date transit agency analysts have not fully taken advantage of its reporting function. The UW has an ORCA data reporting system that currently houses data from January 2019 through May 2022. This project is funding continued improvements to the UW system.

Emerging technologies such as automated vehicles, advanced data analytics and machine learning, and on-demand ride services will not only fundamentally alter the transportation landscape but will provide new data that can be used for transportation planning and analysis. This project is examining the properties of these new data and identifying potential applications. Phase I developed a preliminary framework for integrating emerging and conventional data from diverse sources. Using the Seattle SR 99 Tunnel Tolling Project as a case study, Phase II began to demonstrate the value of emerging big data (more specifically, app-based data) and their fusion with data from other, conventional sources in evaluating a project’s impact on transportation system performance and in answering critical and time-sensitive planning and policy-related questions. This continuation of Phase II will focus on investigating other potential future data sources, such as transportation network companies, insurance providers, and automakers, and on sharing methodologies created for data processing, origin/destination estimation, and validation. The researchers will make all work open source in order to help state, regional, and local agencies better coordinate among agencies and with data providers.
