Driver distraction
is a topic of growing interest to automobile manufacturers and
the public. A major concern is the degree to which operating electronic
devices while driving may distract drivers from the driving task.
A common method for assessing driver distraction is to measure
a number of driver performance variables in a driving simulator
while simultaneously operating an in- vehicle electronic device.
By comparing driving performance prior to operating the electronic
device to performance while operating while operating the device
one can determine whether device operation has a significant detrimental
impact on driving.
Typically,
driving performance data such as speed, lane position or road
conditions are summarized across intervals of time and the summary
data become values in the analysis. However, driving is continuous
in time and summarizing over temporal intervals results in a loss
of potentially valuable information. An alternative is to treat
driving as a temporally continuous process, modeling the impact
of key events (e.g., beginning to operate an electronic device)
on process variables over time. Johnson Controls, Inc. desires
to have a process model developed for analyzing the impact of
input events (operating controls on an electronic device) on continuous
driving performance variables.
