TTR Travel Diary app for iPhone and iPad

This application is for participants of the FHWA Transportation Study. The study is being conducted in Houston, TX, Columbus, OH, and Raleigh-Durham, NC. Participants will use the application to keep a travel diary for commute trips taken on a daily basis for up to 6 weeks. The application will monitor and record routes taken, duration of the trips, and analyze the information against traffic information for roads on the route.

Continued use of GPS running in the background can dramatically decrease battery life.
