TIGG is a mobile app that uses historical traffic data to calculate estimated travel times and tell users when they need to leave to arrive at their destination on time. It is relevant for the 1.6 billion annual leisure travelers, 450 million business travelers, and 36.5 million annual movers in the US. TIGG takes the user's desired arrival time and location, calculates the fastest route based on traffic patterns, and provides customized departure times and alerts. Future updates will incorporate public transit options and integrate with other travel and scheduling apps.
