The Human Research and Engineering Directorate of the U.S. Army Research Laboratory developed a model of the tasks
and workload associated with driving a ground vehicle. The human performance modeling tool, Improved Performance
Research Integration Tool (IMPRINT), was used to simulate the driving tasks. Perception, cognition, and motor control were
represented in the IMPRINT driving model. Human processing, attention, and response were simulated as concurrent discrete
events. Subsequently, the driving model was incorporated into other IMPRINT models used to investigate crew size and
function allocation in Future Combat Systems (FCS) conceptual ground vehicles. Driving is a primary crew function in FCS
ground vehicles. The results of this study indicated that a dedicated driver was recommended in combat vehicles. In all
configurations tested, the driver was consistently the crew member with the highest workload. As expected, results of
simulation runs were consistent with research on driving and distraction. Structural and output validation of the model was
completed through literature review. Driving by itself is a high mental workload function. The human processing capacity is
fully engaged in tasks when one is driving, with the primary load being in perception and cognition. Literature shows that
performance will start to degrade if additional tasks are attempted during driving, especially if the tasks are highly perceptual
or cognitive. This model provides a reasonably simple way to represent the driving function and can be used for investigating
any system where driving is important. For FCS, this will include direct driving and teleoperations. Several additional
validation studies are planned.

In recent years military security forces have operated in a climate of increasing mission complexity and diversity. As a
response to such challenges, the U.S. Army Training and Doctrine Command (TRADOC) approved a concept for a Family
of Integrated Tactical Security Systems (FITSS) involving integrated security sensor systems to support future operations. In
support of this concept the Defense Special Weapons Agency (DSWA), at the request of the U.S. Army Product Manager -
Physical Security Equipment, initiated two exploratory development projects at SPAWAR Systems Center, San Diego, to
develop an Advanced User Interface for Tactical Security (AITS) and a Tactical Sensor Internetting and Integration (TS2I2)
capability. These projects are complementary in approach and application. AITS addresses the human factors and display
technologies needed to effectively support tactical security personnel with sensor information in a clear, intuitive manner while
TS2I2 is focused on a protocol architecture to support control of multiple tactical sensors using current communications
resources. The concepts behind these projects and their current progress are described in this paper. (10 refs.)
