Statistical distribution of time values and underestimation of the benefits of speed

Abstract : Highlights :
• Users' time savings are important in calculating net present value of a transport project.
• The monetary estimates of time savings depend on the value of the time used.
• The official methods of calculation most often use average values.
• Using the statistical distribution of the values of time substantially modifies the result.
• The higher the cost of transportation, the greater the underestimation of user surpluses.
