An Esri team of subject matter experts and software engineers continue to expand and build upon the ArcGIS Platform to support Smart Communities around the world. Building smart communities reflects national, state, regional, and local governments' desire to improve quality of life. When we consider public transit (like buses and subways), these system serve the people of a city by providing access to jobs, education, shopping, healthcare, recreation, and more. Traffic congestion, climate change, and the evolving economy and population of cities has created a greater need than ever to understand how well transit is serving these needs. Explore some of the ArcGIS resources which are available out of the box for public transit agencies to build smart communities.
