The objective of this paper is to develop a mathematicalequation that expresses, in terms of cardinal indices, the relative utilities of the means of transportation. We discussed about men's necessities anddesires, men's tendencies of avoiding pain and searching welfare, andalso the utilities perceived by them in ways that can aliviate such anxieties.In the specific case of passenger transportation, in a situation where thetravel is seen as an intermediate activity, we proposed that intrinsical utilityof the means of transportation can be foundamented on the followingprinciple: all of us, independently of our socieconomic situation, seek toabbreviating the time and physical effort spent by transposition of the distancefrom origin to destination. For this reason we propose that relativeutility of each transportation mode be evaluated as a function of these parameters.The literature on Psychophysics and Ergonomics was reviewedsearching ways by which the sensation elicited by a set of physical orsocioeconomic stimuli are usually quantified. We concluded that the travelmode utility index can be obtained through a multiplicative function whosefactors are powers of the following physical stimuli: straight line distancefrom origin to destination, time, and energy spent by time unity.
