This monograph presents a simple, innovative approach for the
measurement and short-term prediction of highway travel times
based on the fusion of inductive loop detector and toll ticket
data. The methodology is generic and not technologically captive,
allowing it to be easily generalized for other equivalent types
of data. The book shows how Bayesian analysis can be used
to obtain fused estimates that are more reliable than the
original inputs, overcoming some of the drawbacks of travel-time
estimations based on unique data sources. The developed
methodology adds value and obtains the maximum (in terms of
travel time estimation) from the available data, without
recurrent and costly requirements for additional data. The
application of the algorithms to empirical testing in the AP-7
toll highway in Barcelona proves that it is possible to develop
an accurate real-time, travel-time information system on
closed-toll highways with the existing surveillance equipment,
suggesting that highway operators might provide their customers
with such an added value with little additional investment in
technology.
