32 Challenge the future Predicting service reliability Vehicle performance Passenger impacts Travel time impacts AVL data APC data Reliability ratio Additional travel time and variance in travel time units Additional travel time and variance Schedule adherence Transport model - Improved predictions - Predicting and assessing impacts of enhanced service reliability
33
33 Challenge the future The potential benefits Optimizing network and timetable design: The Netherlands: Potential cost savings: > €50 million Utrecht: € 400.000 less yearly operational costs The Hague: 5-15% increased ridership Amsterdam: ~10% increased cost coverage Tram Maastricht:> €4 Million /year social benefits Light rail Utrecht: : €200 Million social benefits
34
34 Challenge the future Much data available Data enables quality increase and enhanced efficiency Substantial benefits Evaluating and controlling -> predicting and optimizing Data-> Information -> Knowledge -> Improvements Two applied examples Passenger data and whatif analysis Vehicle performance and service reliability Summary
