Sara Secunda joined the Volpe Center as a GIS specialist in 2000. She has been involved in GIS-based analyses and developing customized GIS solutions for various modes of transportation. Initially, she provided GIS analysis and programming for National Park Service (NPS), Federal Aviation Administration (FAA), and Federal Motor Carrier Safety Administration (FMCSA). For NPS and FAA, she provided support for the development of air tour management plans including mapping air tour and air flight layers, and generating various input to noise models. In support of FMCSA, she developed and maintains web-based interactive mapping applications for FMCSA's Analysis and Information Online website, which displays historic crash, inspection, and state safety measures data and maps.

As project lead for FHWA’s HEPGIS mapping website, Secunda assisted in development of the interactive mapping application which serves maps and provides an analysis tool for transportation planners. She is currently updating and maintaining the website’s functionality, maps, and data.

Before joining the Center, Secunda worked for 11 years as a GIS specialist in federal and local government as well as private industry.
