Executive summary

TTpred is a set of algorithms that provides accurate travel time prediction based on data captured by inductive loops. It solves the inherent inaccuracies of velocity data provided by loops in congested scenarios applying an automatic correction.
TTpred is integrated in SICE's intelligent transportation systems and has been used in real operation to show predicted travel time on dynamic route information panels (DRIP) in urban expressways like M-30 (Madrid, Spain).
