Impacts of Traffic Safety Awareness on Risky Riding Behaviors among Non-Motorized Cyclists
Traffic safety awareness(TSA)of cyclists plays a crucial role in promoting safe behavior,but it is diffi-cult to directly measure due to its multidimensionality and complexity.To investigate the impact of TSA on risky rid-ing behavior(RRB),safety attitude,risk cognition,safety quality,and external environment are selected as the struc-tural elements(or TSA elements)by using the cloud model,and the empirical research is carried out based on ques-tionnaire data.The"TSA-RRB"structural equation model is developed,and the causal pathway from each TSA ele-ment to RRB is quantified by Mplus 8.0.The Bootstrap method is applied to verify the mediating roles of safety quality,risk cognition,and safety attitude,and the direct and indirect relationships between the external environ-ment and RRB are sorted;subsequently,a hierarchical regression model is employed to validate the moderating ef-fect of traffic safety knowledge(TSK)between TSA and RRB.The findings of this research are concluded as fol-lows.①the proposed structural equation model fits well with questionnaire data,and four TSA elements all have significant negative correlations with RRB.Specifically,risk cognition has the most considerable impact on uninten-tional behavior(-0.331),while safety attitude displays the greatest influence on intentional behavior(-0.332).②Mediating effects show that the external environment,as an exogenous variable,could either directly act on riding behavior or indirectly affect the behavior through other TSA elements such as safety quality,risk cognition,and safe-ty attitude.③The moderation effect of TSK is significant(ΔR2=0.017,P<0.05),enhancing the negative correla-tions between TSA and RRB,and the simple slope relationship between TSA and RRB implies that the effect of TSA on RRB is strengthened when the level of TSK is high.
