Abstract

OBJECTIVE: Drivers' incorrect decisions of crossing signalized intersections at the onset of the yellow change may lead to red-light running (RLR), and RLR crashes result in substantial numbers of severe injuries and property damages. In recent years, some ITS concepts has been focused on reducing RLR by alerting drivers that they are about to violate the signal. The objective of this study is to conduct an experimental investigation on the effectiveness of the red-light violation warning system using voice message.

METHODS: In this study, the prototype concept of the RLR audio warning system was modeled and tested in a high-fidelity driving simulator. According to the concept, when a vehicle is approaching an intersection at the onset of yellow and the time to intersection is longer than the yellow interval, the in-vehicle warning system can activate an audio message of "The red light is impending. Please decelerate!" The intent of the warning design is to encourage drivers who cannot clear intersections during yellow change interval to stop at the intersections.

RESULTS: The experimental results showed that the warning message could dramatically decrease red light running violations by 84.3%. Based on the logistic regression analyses, the drivers without warning were about 86 times more likely to make go-decisions at the onset of yellow and about 15 times more likely to run red lights than those with warning. Additionally, it was also found that the audio warning message could significantly reduce RLR severity because the RLR drivers' red-entry times without warning were longer than with warning.

CONCLUSIONS: This driving simulator study showed a promising effect of the audio in-vehicle warning message on reducing RLR violations and crash potentials. It is worthwhile to further develop the proposed technology into field applications.
