Abstract: Online travel time estimation is receiving increasing attention. However, offline algorithms
remain important, as databases of historical travel times are needed for many intelligent
transportation systems applications. In this paper a parsimonious method is presented for
estimating off-line travel times based on local speed measurements along a route with
uninterrupted flow, e.g., on motorways. The interpolation between the different detector locations
is done by reconstructing trajectories based on traffic flow theoretical principles. The proposed
method is efficient, easy to calibrate and shows reliable results even when detector spacing is
relatively high. The method is compared to other existing methods and validated on a 40 km
