Evaluation of User Perceptions and Behaviors of FAST-TRAC: Pilot Study Results

摘要

The purpose of the User Perceptions and Behaviors evaluation component of FAST-TRAC is to understand how users perceive and value the in-vehicle navigation system, ALI-SCOUT, and to determine how the system is used in the Oakland County study area. Specifically, we want to know if the system helps drivers navigate and reduces their travel times, whether drivers like all or parts of the system, their beliefs about the cost and benefits of the system, whether they would purchase the navigation system, and if so, what they would be willing to pay for it. The study had three main goals: (1) pretest and finalize the methods, procedures, and protocols for the subsequent evaluation tasks; (2) provide preliminary data that can be used as an early assessment of the project; and (3) provide for use in the development of subsequent comparative analyses of behaviors and attitudes among different user groups. The subjects were twice asked to complete a survey, the first after one week of use and the second after two months of use. They were also asked to keep a daily record (called a driver log) of their driving behaviors and use of ALI-SCOUT for one month.
