We have compared Swedish national forecasts for passenger transport produced from 1975
to 2009 with the actual outcomes, and we found substantial differences between forecasts of …

Researchers have improved travel demand forecasting methods in recent decades but
invested relatively little to understand their accuracy. A major barrier has been the lack of …

Different methods to forecast traffic are analysed and discussed. An elementary approach is
to develop heuristics based on the statistical analysis of historical data. Daily traffic demand …

This paper proposes a new way of handling the uncertainties present in transport decision
making based on infrastructure appraisals. The paper suggests to combine the principle of …

Short-term traffic prediction can be defined as the process of estimating the anticipated traffic
conditions in the short-term future given historical and current traffic information (Vlahogianni …

This study reviews the 50-year history of travel demand forecasting models, concentrating
on their accuracy and relevance for public decision-making. Only a few studies of model …

Transport planning is based on traffic forecasts which are subject to great uncertainties.
These uncertainties have generally been ignored or, at least, not explicitly included in the …
