PREFERRED SPEED, ACTUAL SPEED, AND MARGINAL BENEFIT OF TRANSPORTATION RESOURCES

The concept of 'preferred speed' is introduced as the driving speed which maximizes individual utility under ideal driving conditions, subject to a budget constraint. Preferred speed is individual-specific. Actual speed usually falls below preferred speed not only because of congestion, as traditionally defined, but due also to less than ideal road and weather conditions. It is argued that the city shape and structure depend not only on distance from the CBD, but also on the gap between actual and preferred speed. An empirical section uses aggregate data for SMSAs in an attempt to estimate the effect of personal attributes on the preferred driving speed, and the effect of road and weather conditions on the deviation of driving speed from preferred speed. Results are encouraging but disaggregate investigations are needed.
