Abstract:This paper presents a descriptive and explanatory analysis of refueling behavior of gasoline-car drivers. The relationship between drivers' attributes and their refueling behavior is examined using the results of driver surveys conducted at several refueling outlets in northern California. The objectives of the analysis are to identify spatial and temporal characteristics of refueling behavior, and to evaluate the variations in refueling behavior across driver population segments. The results show that refueling behavior is only weakly correlated with demographic and socioeconomic descriptors of the driver. On the other hand, variables representing car ownership and utilization are strongly associated with refueling behavior.
