Rear-end collisions account for about one-third of all traffic crashes on a yearly basis. It has been apparent for some time that the key to perceiving a slower vehicle ahead of us as an imminent hazard, i.e., one requiring immediate action, is a sufficient rate of change of the visual angle of the lead vehicle. This is known as the “looming threshold”, among other things. A number of laboratory researchers have reported values of the looming threshold to be in the range of 0.003 radian/sec… Expand

Using perceptual cues for brake response to a lead vehicle: Comparing threshold and accumulator models of visual looming.
Previously reported effects of the lead vehicle's speed, deceleration rate and headway distance on brake response time were verified in this paper, using a multilevel model and models using τ-1 as the measure of looming fitted better than those using θ˙, indicating that the visual cues drivers used during rear-end collision avoidance may be more close toτ-1.

Accumulation of continuously time-varying sensory evidence constrains neural and behavioral responses in human collision threat detection
This model is capable of predicting the onset of the CPP signature rather than its buildup, suggesting that neural evidence accumulation is implemented differently, possibly in distinct brain regions, in collision detection compared to previously studied paradigms. Expand
Visual information of vehicle velocity acquired by pedestrians involved in road crossing accidents.
A visual model uses the relationship between the tangential and normal components of the velocity to calculate the distance at which the velocity of the vehicle can be perceived by pedestrians, consistent with the timing at which a vehicle collides with a pedestrian most frequently in pedestrian accidents gleaned from accident statistics.

Steer or Brake?: Modeling Drivers’ Collision-Avoidance Behavior by Using Perceptual Cues
Driver models have been developed to capture collision-avoidance behaviors, yet there is a lack of understanding of what perceptual processes influence drivers’ choices to brake or steer. AExpand
A comparison of computational driver models using naturalistic and test-track data from cyclist-overtaking manoeuvres
The models compared in this paper may support the virtual safety assessment of ADAS so that driver behaviour may be considered in the design and evaluation of new safety systems. Expand
A farewell to brake reaction times? Kinematics-dependent brake response in naturalistic rear-end emergencies.
It is argued that a naturalistic braking response should not be thought of as a slow reaction to some single, researcher-defined "hazard onset", but instead as a relatively fast response to the visual looming cues that build up later on in the evolving traffic scenario. Expand
Predicting driver reaction time and deceleration: Comparison of perception-reaction thresholds and evidence accumulation framework.
The evidence accumulation framework is a promising method of predicting driver reaction in approaching and braking conditions for different types of lead vehicle, and the level of urgency is important for predicting the probability of crash. Expand
Impact of the connected vehicle environment on tunnel entrance zone.
The results show that in the connected vehicle environment, the drivers' speed control in the warning zone is improved and their deceleration behavior is advanced, which will help vehicle manufacturers in designing safety-related functions of automated vehicles. Expand
Modeling driver control behavior in both routine and near-accident driving
Building on ideas from contemporary neuroscience, a framework is proposed in which drivers’ steering and pedal behavior is modeled as a series of individual control adjustments, triggered afterExpand
The Role of Situation Criticality in Affecting the Effect of Cognitive Load on Drivers’ Brake responses: A Driving Simulator Based Study
Results demonstrated that the previously proposed mechanistically explicit simulation model was able to predict drivers’ brake response times on different levels of cognitive load and the increased effect of Cognitive load on Drivers’ brakes response times in less critical situations was demonstrated in this paper.

Relationship Between Relative Velocity Detection and Driver Response Times in Vehicle Following Situations
Several previous studies report driver response times when responding to a lead vehicle. There have also been other studies that examined and measured the ability of drivers to detect the relativeExpand
Forensic Aspects of Driver Perception and Response
Many accident cases come down to questions of what a driver could have or should have seen and/or how long it would take a driver to respond in an emergency situation. This book pulls together theExpand
