Abstract

Deterrence Legitimacy Point-to-point Procedural justice Risk perceptions Speeding
Introduction: Speeding continues to be the largest contributor to road fatalities, with speed enforcement the primary countermeasure in place to prevent this behavior. Mobile average speed cameras have the potential to further prevent speeding behavior, as they are more unpredictable and can capture speeding along wider lengths of road. However, little is known about how drivers perceive these cameras, including deterrence related perceptions and perceptions of procedural justice. As such, this study aimed to examine the perceptions, attitudes, and concerns about mobile average speed camera enforcement methods, compared to other traditional methods (e.g., fixed spot speed cameras, mobile spot speed cameras, vehicle mounted mobile radar, and fixed average speed cameras). Method: A total of 887 respondents (M age = 42.8 years, SD = 17.7 years), completed a cross-sectional survey. Results: It was identified that mobile average speed enforcement occupied a middle ground in terms of deterrence perceptions compared to the other enforcement methods, yet they were viewed less favorably than fixed enforcement methods in terms of fairness, respect, and trustworthiness. Correlations, a linear regression and ANOVAs revealed the large role dysfunctional attitudes plays in intention to speed when there is mobile average speed enforcement. It was also found that respondents expressed reduced confidence in mobile average speed camera effectiveness across complex road environments, particularly among those holding stronger dysfunctional, pro-speeding attitudes. Conclusions: The results highlight that, in addition to deterrence capacity, perceived legitimacy and attitudes towards speeding can influence the effectiveness of mobile average speed enforcement. Practical Applications: The findings therefore suggest that transparent implementation, community engagement, and complementary behavioral interventions should also be considered to maximize road safety outcomes.
