Measuring the Impact of Advanced Transportation Technologies on Traveler Behavior

Travelers are active participants in transportation network operations, said Jane Lappin, a senior social scientist, at Volpe, The National Transportation Systems Center. Since 1997, a Volpe team surveyed over 16,000 travelers—most of them repeatedly. Volpe has analyzed over 30,000 surveys to learn how travelers use information and to better understand the impact of traveler information on their trip choices.
