Senior Engineer

Alison Tanaka

Alison’s professional focus is on traffic signal systems, and she applies that passion to a wide range of projects. During the planning stages, she often uses her expertise to refine traffic operations and multi-modal alternative analyses. She has experience in taking preliminary plans through final traffic signal and interconnect design, even at locations with complicated geometry such as those near railroad crossings. In addition, Alison has produced both new traffic signal timing plans and adjusted existing timing plans. She is currently working with several agencies in the emerging area of automated traffic signal performance measures, which can be used to inform traffic signal timing plans, as well as used for continuous monitoring. In the interest of moving the profession forward, Alison is also heavily involved in national research. She was a lead author for NCHRP Report 812: Signal Timing Manual, 2nd Edition, and is currently working on NCHRP Project 03-122: Performance-Based Management of Traffic Signals. When not at the office, Alison can be found enjoying the outdoors and the top-notch food scene around Portland.
