SOAR as a Cognitive
Architecture for Modeling
Driver Workload

Randall Mauldin


To have onboard computer assistance
that allows safe multi
tasking while

Reduction of accidents and unsafe
driving due to the distraction of
secondary tasks proves to be a cause
worth pursuing.


Develop a Computational Cognitive
Model of the driving task to allow a
safer and more efficient driving


Develop a Cognitive Process Model
(CPM) of a basic driver workload.

The C

will take in to account

driver tasks and interpret their

on cognition.

Develop computational specifications
and implement them into a Cognitive
Modeling Architecture.

Possibilities for a CPM

What is Driver Distraction?

Driver distraction lacks a precise,
scientific definition.

Defined based upon four components:
Impact, Agent, Mechanism, and Type.

Impact and Agent

“A driver is delayed in the recognition of
information necessary to safely maintain
the lateral and longitudinal control of the
vehicle (the driving task)”

“Due to some event, activity, object or
person, within or outside the vehicle”

Mechanism and Type

“That compels or tends to induce the
driver’s shifting attention away from
fundamental driving tasks”

“By compromising the driver’s auditory,
biomechanical, cognitive or visual
faculties, or combinations thereof”


State Operator and Result

Created by John Laird, Allen Newell,
and Paul Rosenbloom at Carnegie
Mellon University in 1983.

The “state” is the situation that needs
to be solved.

The “operator” is what changes the


Soar’s 7 step decision cycle


Structural model of Soar’s operation

Key Features

Capable of representing large complex
rule sets

Learns in a problem
solving context

New rules created for shorter
sequences (“chunking”)
