We present a method to predict the time that will be needed to
traverse a certain stretch of freeway when departure is at a certain
time in the future. The prediction is done on the basis of the current
traffic situation in combination with historical data. We argue that,
for our purpose, the current situation of a stretch of freeway is well
summarized by the 'current status travel time'. This is the travel time
that would result if one were to depart immediately and no significant
changes in the traffic would occur. This current status travel time can
be estimated from single or double loop detectors, video data, probe
vehicles or by any other means. Our prediction method arises from the
empirical fact that there exists a linear relationship between any
future travel time and the current status travel time. The slope and
intercept of this relationship is observed to change subject to the time
of day and the time until departure. This naturally leads to a
prediction scheme by means of linear regression with time varying
coefficients
