Tracy Hadden Loh has long been interested in urban infrastructure and federal policy. Her background in computational math and urban studies gives her a unique set of skills as research manager for RTC, where she helps keep the organization’s studies and reports cutting edge in a complex transportation landscape. Her dual role is as director of the Transportation Alternatives Data Exchange (TrADE), a vital resource cataloguing federal investment in pedestrian and bicycle facilities, as well as other key improvements to America's transportation system. Tracy says what she finds most rewarding is collaborating with transportation planners, engineers, and local project sponsors to realize meaningful community improvements.
