Managing data to drive decision making has never been more important.  As large data systems are capturing significant performance, operational and planning data in the transit industry.  These data can improve decision making, service evaluation, customer satisfaction, operational efficiency and overall system performance. At the core of many of these data are spatial elements, that describe the location of relevant transit data.  Transit boardings, customer location, activity centers, assets and transit service.  Geographic Information Systems (GIS) provides a unique platform for organizing, evaluating and communicating data; transforming data into information.  This conference will bring experts from around the country on how GIS is being used everyday to improve transit systems.  The conference will provide a breadth of GIS experiences to showcase how agencies of all sizes and budgets are managing its GIS data and improving transit service and ultimately customer service.
