Abstract: Collision warning systems have been identified as an effective technique for avoiding accidents. In such a system, the delivery time of warning messages is a crucial factor that influences the success of collision avoidance. This study therefore contributes by providing experimental analyses on a range of delivery times of warning messages, which has been overlooked in past studies. Using simulator-based techniques, experimental scenarios are specifically designed for accounting the red-light-running events at intersections and drivers are recruited to test on different settings of warning timings. Several measures including brake reaction time, alarm-to-brake-onset time and deceleration are adopted as reflections of drivers’ performances under the collision avoidance process and they are connected to several factors by mixed effect models. According to the results, the collision warning system actually can largely reduce the occurrence of red-light-running collisions, more importantly it reveals the influence of warning timings within the predefined ranges and 4.0 s or 4.5 s may be a proper warning timing for the right-angle collisions accused by red-light-running vehicles in this study. Besides, effects from directional information embedded in warning messages are also investigated in this study. Findings are important to the design of collision warning systems especially in the aspect of warning timings.

TL;DR: The results showed that the hands-free condition did not eliminate the safety problem associated with distracted driving because it impaired the driving performance in the same way as much as the use of hand-held phones, and shed some light on the further development of advanced collision avoidance technologies and the targeted intervention strategies about cell phone use.

TL;DR: Requirement can be derived for the design of effective warning strategies for critical intersections by providing a clear warning with directional information about an urgent hazard event to give drivers adequate time to prepare for the potential collision.

TL;DR: In this article, the influence of ICAWS warning conditions on drivers' visual performance was explored by exploring the patterns in drivers' eye movements as a function of ICWAS warning conditions in red light running scenarios.

TL;DR: A driving simulator-based experiment to understand the effects of lane-end sign distance and traffic volume on driving behaviors and finds male or taxi drivers tended to act earlier than female or regular drivers respectively, for all the three stages.
