A MODEL FOR TRAFFIC DELAY AND ITS CONVENIENCE AND WAGE COSTS

One of the large problems facing engineers in the economic analysis of public projects is the estimation of comfort and convenience costs and of lost wage costs. Comfort and convenience costs have generally been either ignored or treated as a linear function of the trip delay time; wages lost to tardiness have also generally been assumed to be linear when they have been considered at all. But personal experience argues against the idea of a linear comfort and convenience cost-except in unusual circumstances, short delays in the completion of a trip have negligible actual costs. Similarly the wage loss due to tardiness is recognized to have a zero value when the tardiness is below some threshold value, and this threshold value is recognized in most union contracts. This paper treats the problem of calculating comfort and conveninece costs analytically and proposes a probability distribution that is easily used to estimate the value per person trip of both such costs. This technique is then applied to cost estimation where the delay is caused by snow and ice on a roadway. /Authors/
