With 13 years of public- and private-sector experience in transportation planning, Tien-Tien (“Tim-Tim”) has led more than 40 parking, TDM, and multimodal projects. Her foundational work co-authoring CAPCOA’s Quantifying Greenhouse Gas Mitigation Measures established a framework for implementation of TDM, and led to her work on transformative projects such as San Francisco’s TDM Program Standards and the City of Austin’s land development code overhaul. Prior to joining Nelson\Nygaard, Tien-Tien served as Technical Project Manager for the MBTA’s Customer Technology Department and as TDM Program Manager for the City of Austin, where she established the City’s first ever TDM program. She currently serves as co-chair of the Transportation Research Board’s committee on TDM.
