N2  - The way in which time is converted into money is becoming increasingly important in transportation planning. In particular, the pricing of time is becoming more and more decisive for the calculated profitability and realization of road projects. The general trend is toward more and more traffic but smaller and smaller individual time savings, although, as always, such savings are discrete in time and space. These and other circumstances create very real problems of pricing, especially in view of the aggregation problem. It is argued that the problems of aggregation are ignored in the application of, and maybe in, economic theory itself. Whether this assertion is wrong or right, it raises the all-important question of how robust a theory is with respect to deviations from the underlying constraints before the application of that theory collapses in terms of validity of the results. The impression is that in the application of the time utilization theory the effects of such deviations have been ignored, which makes much of the present use of time in transport both meaningless and misleading. Pertinent questions about research problems and bottlenecks for a credible practical application of time utilization theories are raised.
