RideScout is a smartphone application that aggregates all ground transportation options around a user in real time; the Kayak™ of ground transportation. The RideScout mobile platform finds information on nearby buses, trains, taxis, and carsharing programs, while also integrating seamlessly with other transportation apps, displaying results on one simple interface. Facebook integration allows for ridesharing and trip planning with friends. Users can quickly sort options by both time and cost. The app is currently optimized for Washington, DC but will be rolling out in San Francisco and other major cities in the coming months.
