Traffic liaison with local agencies, developers, consultants, and capital improvement projects (Connecting Washington). Supervised a team of two engineers.Spearheaded traffic engineering and operations within the King County area, leading initiatives in one of the top-ten most congested metropolitan areas in the U.S. Directed comprehensive traffic analysis and design reviews, supporting capital programs and local agency projects, enhancing system efficiency and safety through the application of policies and standards. Managed traffic design guidance and quality assurance for major corridor projects, including the enforcement and advocacy of active mobility policies and best practices. Led traffic modeling efforts using tools such as VISSIM, Synchro, and SIDRA, developing operational improvements for state highway projects. Facilitated effective stakeholder engagement, coordinating with local municipalities, transit agencies, and consultancies to develop integrated transportation projects, emphasizing strong communication skills and collaboration.-Project Highlight-SR 900 and SR 202 Corridor Planning Studies (June 2020 - June 2022)As Project Manager and technical lead, I initiated a plan to address community dissatisfaction with outdated, high-speed, vehicle-centric corridors. I advocated for and secured departmental support for two studies, and initiated a framework to apply essential elements of state policy, engagement and safety, while utilizing internal resources to preserve budget.I engaged with stakeholders through surveys, meetings, and forums to identify problems and solutions. As a contributing author, I oversaw the draft report and presented recommendations to an executive committee. I secured consensus for wide sidewalks, community placemaking features, and speed reduction strategies, and I completed the studies with a budget five times smaller than typical studies.

Provided support in traffic design and operations, reviewing internal and external project designs to ensure safe and efficient travel across all modes of transportation. Conducted data analysis and reporting on overall traffic system health and during major construction events.-Project Highlight-State Route 169 Safety Study (August 2016 - June 2017)As the sole author of the study, I tackled the challenges of an older, high-speed, two-lane highway with a narrow cross-section and a history of fatal and serious injury crashes. With high-cost projects remaining unfunded, my goal was to identify near-term, lower-cost safety recommendations.For the study, I compiled and analyzed five years of crash and traffic data. I developed Synchro intersection and SIDRA roundabout models for both no-build and build scenarios and created GIS maps illustrating crashes, traffic volumes, and safety recommendations.I then authored the report and designed the graphics, presenting the findings to the executive committee and gaining their approval. Additionally, I met with elected officials to discuss the study's findings and followed through with the implementation of the recommended near-term safety improvements.

As the lead of a 15-member team, responded to emergent conditions on state highways, implemented novel Intelligent Transportation Systems (ITS) solutions, showcasing leadership and technical expertise with the implementation of the region’s first dynamically tolled freeway.-Project Highlight-I-405 Express TollApril 2014 - January 2016As an Operations Engineer and Supervisor in the Traffic Management Center, I was responsible for implementing and tuning the toll rate algorithm for the new tolled facility on Interstate 405 in the Seattle area. This project aimed to alleviate congestion during peak hours, providing a reliable commute for transit, HOV, and other users, while offering SOV traffic a paid option for a more dependable trip.The unique challenge was balancing traffic demand, travel speeds, and toll pricing across a 15-mile corridor. I established operational parameters for the first use of a fuzzy logic algorithm for a tolled facility in the US. Using R, I created a simulation suite to iterate through 134 pricing scenarios, optimizing toll rates based on several months of data from over 100 traffic detectors.I created visualizations to demonstrate the optimized results, building consensus among internal stakeholders. I deployed the toll algorithm parameters and supported the project after go-live with continuous monitoring, reporting, and tuning. Additionally, I acted as a spokesperson for live media interviews to explain how dynamic toll rates are calculated.

Operate and implement ITS systems and supervise Traffic Management Center response to emergent conditions on state highways. -Project Highlight-Active Traffic ManagementNovember 2009 to August 2011As an Operations Engineer in the Traffic Management Center, I spearheaded the implementation of Active Traffic Management (ATM) to address congestion on 37 miles of Seattle's freeways, including I-5, I-90, and SR 520. The project featured a speed harmonization algorithm, lane closure management protocol, and overhead signs every half mile to relay messages to drivers.I tested, programmed, and implemented the advanced traffic management systems, serving as the technical expert for sign communication protocols. This involved managing acceptance testing of sign firmware and displays, resolving issues with vendors and software developers, and configuring hardware and software for operation.Additionally, I designed visual display symbols to aid drivers navigating the system, managed testing of the software user interface, and trained staff. As part of reporting requirements, I formulated performance metrics, collected and analyzed data, created data visualizations, authored a comprehensive report, and demonstrated operational improvements to federal authorities.

Conducted in-depth analysis of traffic data to identify trends and recommend remedial strategies for roadways with safety concerns, effectively contributing to the prioritization and allocation of funding towards high-need locations.-Project Highlight-Intersection Prioritization ArrayAugust 2009As a Traffic Safety Analyst, I led a project to identify and prioritize intersections with serious injury and fatal crashes on state highways. Recognizing that fatality crashes, due to their random nature, are not always indicative of systemic safety issues, the goal was to find underlying patterns and rank intersections accordingly.The project began with Microsoft Excel, but I quickly realized a more sophisticated approach was needed. Utilizing GIS and SQL, I quickly linked geospatial data with roadway and crash information. GIS was particularly useful in grouping crashes at intersections assigned to multiple approaches and locations in the vicinity. The next step involved identifying crash types and intersection characteristics that lead to severe crashes, such as posted speed limits and crash types like rear-end and angle crashes.I then formulated and implemented a prioritization matrix to rank 5,244 intersections based on these features. This allowed for more effective allocation of investments based on operational performance. I presented the results to executives, demonstrating the process and contributing to a more efficient prioritization of funding towards high-need locations.
