چکیده

Collision warning systems offer a promising approach to mitigate rear-end collisions, but substantial uncertainty exists regarding the joint performance of the driver and the collision warning algorithms. A simple deterministic model of driver performance was used to examine kinematics-based and perceptual-based rear-end collision avoidance algorithms over a range of collision situations, algorithm parameters, and assumptions regarding driver performance. The results show that the assumptions concerning driver reaction times have important consequences for algorithm performance, with underestimates dramatically undermining the safety benefit of the warning. Additionally, under some circumstances, when drivers rely on the warning algorithms, larger headways can result in more severe collisions. This reflects the nonlinear interaction among the collision situation, the algorithm, and driver response that should not be attributed to the complexities of driver behavior but to the kinematics of the situation. Comparisons made with experimental data demonstrate that a simple human performance model can capture important elements of system performance and complement expensive human-in-the-loop experiments. Actual or potential applications of this research include selection of an appropriate algorithm, more accurate specification of algorithm parameters, and guidance for future experiments.

V2V Wireless Communication Protocol for Rear-End Collision Avoidance on Highways

More than 23% of annual vehicle accidents are rear-end collisions, which provides an important test-case for enhanced collision avoidance approaches based on v2v wireless communications. In this work, we propose and study the impact of a 802.11 based multi-hop MAC protocol that propagates an emergency warning message (EWM) down a platoon of cars on a highway. The design objective is to ensure r...

Control of Vehicle Braking by Younger and Older Drivers: The Effect of Texture and Size Information

Safe driving performance includes the successful detection and avoidance of an impending collision. Of all crash types, rear end collisions account for a high number of vehicle crashes. For example, data from the NHTSA 2003 General Estimates system indicated that rear-end crashes accounted for 28% of police reported crashes in the United States and is a rate higher than other types of high cras...

Development and evaluation of collision warning/collision avoidance algorithms using an errable driver model

Collision warning/collision avoidance (CW/CA) systems must be designed to work seamlessly with a human driver, providing warning or control actions when the driver’s response (or lack of) is deemed inappropriate. The effectiveness of CW/CA systems working with a human driver needs to be evaluated thoroughly because of legal/liability and other (e.g. traffic flow) concerns. CW/CA systems tuned o...

On-scene Determination of Driver Crash Causation and Avoidance Maneuvers in Rear-end Collisions

Rear-end collisions are one of the most frequent crash types in the U.S. Pre-Collision System (PCS) have been developed to mitigate the frequency and severity of rear-end collisions. The potential effectiveness of these systems, however, depends on the driver’s state and their attempted avoidance maneuvers. This study utilized the National Motor Vehicle Crash Causation Survey (NMVCCS), a unique...
