The impact of perceived risk on urban commuters' route choices

摘要

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, multinomiallogit model with perceived risk variable was specified and estimated. A number of route choice models were estimated for different groups of the driver population. The groups were identified on the basis of age, gender number of children, marital status, household monthly income, and level of traffic information.
