These demands on attention, such as dispatch radio calls, are necessary for the officer to perform the patrol and thus cannot be eliminated without compromising the officer’s effectiveness. This project evaluated law enforcement officers’ driving, visual attention, and situation awareness during patrol driving. We varied conditions to determine the impact of information presentation format on officers’ ability to execute patrols. In addition, we were interested in how the growing number of in-vehicle technologies may be able to provide additional support to the officer and reduce the impact of information overload. Fourteen municipal law enforcement officers, recruited from local law enforcement agencies, performed patrols using a driving simulator under general patrol conditions: baseline patrol driving, patrol driving with radio calls, and patrol driving with radio calls and an in-car data terminal. We anticipated that the need to process information over the radio would lead to changes in driving behavior (e.g., steering and lane position variability), visual attention deployment (e.g., eye movements), and situation awareness (e.g., current status of self and other officers). We also expected that the provision of redundant information via an in-car terminal would reduce the impact of this additional demand on the officer’s attention. Finally, we were interested in the structure of information transmitted to the officers during patrol. We presented radio calls in both ten-codes (e.g. 10-20 = location) commonly used in police departments or in a more natural language structure (e.g., “What is your location?”) Ten-codes are brief but sacrifice transparency of the message. Whereas natural language structure may be easier to understand, it can require a longer transmission time. We presented information in both formats during simulated patrols to determine if one type of transmission type has a lower impact on officers’ driving, visual attention, and situation awareness. Analysis of variance plus post-hoc planned comparisons were used to evaluate the impact of information format and language structure on driving behavior, visual attention, and situation awareness measures. Our results indicate that when ten-codes are paired with a display echoing communication with dispatch or when natural language is used without such a display, accuracy on a test of situation awareness was similar to a baseline condition without distraction. This provides evidence that police departments should be made more aware of how certain technologies and practices interact. |
