CarFreeAtoZ is a multimodal trip planning and comparison tool for Arlington county and that Washington DC area. Trips are shown as combinations of metro, bus, car, bike, bikeshare, and walking. The trips are compared on five factors: total trip time, cost, walk distance, calories burned, and productive time.[1]

The website was developed by Arlington County Commuter Services (ACCS) as part of a Transit Tech Initiative.[2] ACCS contracted with Conveyal, which leveraged its Modeify application to create the multimodal trips and comparisons.

CarFreeAtoZ uses a number of open data transportation standards and tools to build up its maps and important transit data. These include OpenTripPlanner, OpenStreetMap, and GTFS.
