Incorporating Ride-Sourcing Service into ADA Paratransit
This web post summarizes a technology transfer project co-funded by PacTrans and King County Metro Transit on leveraging ride-sourcing services a part of ADA paratransit. In early December 2021, PacTrans PI and Professor of Urban Design and Planning at the University of Washington, Qing Shen, and a Graduate Research Assistant in the Interdisciplinary PhD Program in Urban Design and Planning at the University of Washington, Lamis Ashour, delivered a webinar titled, Incorporating Ride-Sourcing Service into ADA Paratransit: Opportunities and Challenges for Public Transit Agencies.

PacTrans Technology Transfer Success Story 2019 #4: Simulation Environment to Optimize Public Investments in Battery-Powered Vehicle Charging Infrastructure
A research team at the University of Washington, led by UW Professor Don MacKenzie, recently developed a decision support system (EVI-DSS) to guide the WSDOT’s infrastructure development process. EVI-DSS is a model-view-controller application capable of supporting multiple users concurrently. It employs a PostgreSQL database as a model, two R Shiny web-apps as views and a NodeJS server for managing analysis execution requests.

PacTrans Technology Transfer Success Story 2019 #3: Uncrewed Aircraft Systems in Transportation: Research-to-Operation Peer Exchange
Over the course of PacTrans’ existence, we have funded a number of projects the explore various applications of uncrewed aircraft systems (UAS), or drones. One of these PIs, OSU Professor Christopher Parrish, has also taken the lead on facilitating a larger regional and national dialogue about unresolved challenges, best practices, and other aspects surround the implementation of UAS in DOT workflows. So, for example, using previous PacTrans Technology Transfer Success Story funding, Dr. Parrish hosted a UAS in Transportation workshop back in 2018.

PacTrans Technology Transfer Success Story 2019 #2: Extraction and Classification of Pavement Marking Program
Several years ago, OSU Professor Michael Olsen worked on a project in partnership with the Oregon Department of Transportation, where his team developed the Road Marking Extractor (RoME) tool to extract near-linear pavement markings from mobile lidar data. The following year, with PacTrans funding his team expanded that work with a project titled, “Efficient Extraction and Evaluation of Complex Pavement Markings from Mobile Laser Scan Data,” where they broadened the capabilities of the RoME tool to implement complex marking extraction (e.g., insertion lanes, arrows, text), improved noise filtering, deep learning-based classification, and rigorous tests on real-world data in various noise and road conditions.
