enmodal is a planning and analysis tool that allows you to create, modify, and share transit maps.
Using a simple, intuitive browser app, you can draw new transit modes or modify existing ones. An analysis engine in the cloud feeds estimates for ridership and cost based on socioeconomic and historical data.
enmodal is an open-source project that is free to use. Although one can create maps anywhere in the world, the analysis engine is presently limited to locations in the United States.
