Ranking and Causal Relationship Analysis of Incentive Factors of Driving Anger: A Case Study from an On-Road Experiment in China

It is widely recognized that driving anger plays a major role in road safety. Many studies have been carried out in this field, and the significance of incentive factors of driving anger -- in terms of driver's personal characteristics (e.g., sex or education) and external environment (e.g., interaction among drivers and obstruction) -- has been proven. Questionnaire surveys and simulation experiments are used as the basis for those studies, but such methods make the studies very unrealistic. In this study, 22 licensed drivers were hired to drive along a specified route in Wuhan, China. Physiological data and drivers' reported driving anger and observed driving behavior are used to study the ranking of the contribution of various incentive factors to and their causal relationship with driving anger. Study results show that the following top three factors result in about three quarters of driving anger: (1) red traffic lights, (2) congestion, and (3) offensive hogging behavior of surrounding vehicles. Further, statistical analyses show that the p-values from the Somers-d test applied to red light waiting times and congestion duration, and from the F-test to hogging behavior are very small (< 0.02) and, thus, indicate that they have a significant impact on the level of driving anger. In general, this study contributes to this field by using both self-reported data and in-cabin observations to study the ranking of incentive factors and their causal relationship with driving anger in a typical driving environment in China. Study results can be useful for traffic operation and management agencies in China to improve their level of service in order to effectively reduce road rage.
