Predictors of speeding among drivers based on Prototype Willingness Model

Speeding is a major contributor of road crashes among young driver and caused 40% of fatal crashes. the purpose of this study was determining predictor of speeding intention among drivers in ghaemshahr based on prototype willingness model (pwm). in this cross sectional studies 114 young drivers entered in this study with a clustered random sampling from population of urban health care of ghaemshahr in 2012. data were collected by using a self-reported questionnaire that contains demographic factors and prototype willingness model constructs. the validity and reliability of the scale were approved. the result showed that speeding intention was correlated to all variables except description of the typical other driving, and regression model explained 63.4% of the speeding intention variance. determinants of the intention to speeding were mostly past behavior, subjective norms, perceived similarity of the prototype, description of the typical other driving, driving experience and attitude. also intention, willingness and driving experience predicted the speeding behavior. results highlight the importance of attitude, normative aspect and driving experience in the speeding intention and these factors used for designing educational program aimed to reduce speeding and road crashes.
