DACCORD: ON-LINE TRAVEL TIME ESTIMATION/PREDICTION RESULTS

This paper deals with part of the achievements of the European project DACCORD. Within the framework of DACCORD a number of methods for on-line travel time estimation and prediction have been developed, implemented, validated and evaluated. This paper provides an overview of the methodologies involved, but focuses on the evaluation results. Evaluation results and cross site comparisons are presented for a number of different methods that were demonstrated at three test sites which participated in DACCORD. Results show that on-line (i.e. real time) travel time estimation using induction loops can be achieved with errors around 10 % (up to moderate congestion levels). The results also show that on-line methods require a substantial effort to deal with the operational performance of the currently available monitoring systems.
