Computer vision in vehicle and driver performance
… identifies the key aspects required to measure driver performance and statistical analysis is performed on a number of participants conducting driving events around a specified route around Oxford, England. Steering, throttle and braking parameters are measured, analysed and characteristic …

Characterizing the effects of videophone conversations on younger and older driver performance
Driver distraction is a widespread and growing issue. Previous studies have shown that passenger conversations can be less distracting than cell phone conversations because of an increase in shared situational awareness when the conversation partner can see the driver and driving scene. Recently, …

The influence of motion and audio cues on driver performance in an automobile simulator
… to investigate the influence of these cues on driver performance. Forty-eight student subjects were randomly allocated to six experimental groups. Each group of eight subjects experienced a unique combination of the motion and audio cues. The control group performed under a full simulation …

Evaluation of Driver Performance While Making Unprotected Intersection Turns Utilizing Naturalistic Data Integration Methods
… here uses an empirical approach to study driver behavior at intersections, in a naturalistic paradigm. A data-mining algorithm was used to aggregate the data from two different naturalistic databases to obtain instances of unprotected turns at the same intersection. Several dependent …

The Effects of Life Stress and Risk-Taking Style on Risk Perception and Driver Performance
… style, stress level, and highway environment on driver performance. In Phase I, 50 subjects were assessed for risk-taking style and stress level. In Phase II, the same subjects were presented with slides of traffic situations that varied in terms of risk of accident. This was a paired comparison …

The Effect of Directional Auditory Cues on Driver Performance in a Simulated Truck Cab Environment
… containing no secondary task. Both driving performance (lane deviation, steering wheel angle, road heading angle error, accidents, and adherence to the speed limit) and secondary task performance (accuracy and response time) measures were collected. Results showed that drivers were able to …

Effects of Visibility and Alarm Modality on Workload, Trust in Automation, Situation Awareness, and Driver Performance
<p>Driving demands sustained driver attention. This attentional demand increases with decreasing field visibility. In the past researchers have explored and investigated how collision avoidance warning systems (CAWS) help improve driving performance. The goal of the present study is to determine …

A multivariate investigation of driver performance changes during extended driving periods in a computer-controlled driving simulator
… of driving time on nine continuous measures of driver performance and alertness, and to determine the extent to which such variables could be used to predict driver performance degradations in driving emergencies. Subjects were required to respond to one of three types of driving emergencies …

The Distracted Driver: Modeling the Impact of Information Bandwidth, in -Vehicle Task Priority, and Spatial -Separation on Driver Performance and Attention Allocation
… the automobile creates additional tasks that drivers may perform while driving. To the extent that these devices interfere with driving performance there will be concerns for safety. In three experiments, we explored how characteristics of the IVT task as well as the traffic environment impact …

Identify Mind Wandering Behind the Wheel
Driver distraction is a significant risk factor for traffic crashes. Distraction from secondary tasks has been the basis of much research and legislation. However, the influence of cognitive distraction, or mind wandering (Smallwood & Schooler, 2006), on driver performance has not been as closely …

An Assessment of the Attention Demand Associated with the Processing of Information for In-Vehicle Information Systems (IVIS)
… the amount of information provided to the driver; therefore, steps must be taken to ensure they do not require a high attention demand. (Limited attention resources can be diverted from the primary task of driving to a secondary in-vehicle task). The attention demand required as part of the …
