Determination and Evaluation of Traffic Congestion Costs

Abstract

The current estimation of time loss and costs of traffic congestion is lacking a scientifically valid empirical database concering the queue speed and time loss, as well as a methodological soundness of the value-of-time of commuting and leisure, and may hence lead to serious errors. In fact, the low willingness-to-pay of commuters for using a toll road indicates that the benefit of traffic time gains is estimated to be much lower than a significant part of the wages.
