Fig. 18.3 Route used for the recording (5.6 miles long). Subjects drove this route two times. In the
first lap, the subjects performed the tasks in order, starting with the Radio task and ending with the
Conversation task. In the second lap, the subjects drove the same route without performing any
task. The second lap involves normal driving without any of the aforementioned tasks, which is
used as a normal reference. Since the same route is used for both normal and task conditions, the
analysis is less dependent on the selected road
randomly selected pictures and the driver is asked to describe them (route D in
Fig. 18.3 ). The purpose of this task is to collect approximated (and maybe
exaggerated) data from distractions caused by billboards, sign boards, and shops.
The last task corresponds to spontaneous conversation between the driver and a
passenger, who asked few general questions (route E in Fig. 18.3 ). After subdividing
the phone and GPS tasks, the database includes the following seven tasks: Radio ,
GPS Operating , GPS Following , Phone Operating , Phone Talking , Picture , and
Conversation .
