Estimated Value of Savings in Travel Time in Switzerland Analysis of Pooled Data

Reliable measures of the value of travel time savings (VTTS) are crucial inputs into policy planning in any regional or national context. However, the evidence from secondary or parallel VTTS studies often differs from that from official or national studies. This paper presents evidence from a study aimed at merging evidence from four separate studies of VTTS conducted in Switzerland. The analysis shows the potential of models estimated jointly on the basis of the combined data and produces stable results that should be more representative or those for the overall population.
