Abstract

This paper investigates the impact of the perceived risk on a driver's route choice decision-making process. The underlying premise was that a driver's perception of risk is a key component of a driver's route choice decision-making process. To accomplish this, a perceived risk model was developed and estimated. The output of this model is referred to as the level of expected perceived risk. A route choice, multinomial logit model with perceived risk variable was specified and estimated. A number of route choice models were estimated for different groups of the driver population. Estimation results indicated that as the level of expected perceived risk increases, a driver is unlikely to select the route. The results also indicated the need to estimate a separate route choice, with a perceived risk variable, multinomial logit model for each identified group of the driver population. The results also showed that a driver's route switching behavior increases with increasing route travel time and the existence of alternative routes.
