Objectives Investigation of modal-split characteristics to support transport policy of Budapest and strategy of BKV Harmonisation of supply based on the measured flows within network planning Brush up marketing by collecting the opinions/judgments on public transport services Calibration of performance factors (average number of boardings, average trip length, etc.) used to calculate the number of passengers and passenger performances by ticket type

Determination of the key drivers of mode choice

Survey sheet of trips from to trip purpose departure time mode of travel detailed questions for trip legs depending on mode choice

Judgments and decision making factors judgment of burdens caused by city-life mode choice satisfaction with BKV alternative operators (MÁV and VOLÁN) judgment of fare dodgers at car users: Why? In which case would you choose other means of transport? Would you mind to use P+R facilities?

Distribution of communal homes in Budapest 43858 tenants (HCSO, 2001) disproportionate area distribution concentrated, partly homogeneous transport demand decisive local role

Development of the market research software (CAPI) More accurate No need for coding, recording and the extra costs caused by them (time, personal, mistakes) can be avoided Cheaper, ~ 20% less Homogeneous computer farm More details and better quality More efficient post processing capabilities Developer: CData (T-SYSTEMS) under supervision of TRANSMAN

Program characteristics RDBMS (Ms Access) Digital map based Internalization of PT services (encoding) System design based on the survey book

Sample size Statistical analysis/tests on sample size (1%, 2%, 4%, 8%), confidence levels and probable deviation Confidence level (90% and 95%) The deviation is pretty low on trip rates, 1% sample size – less 2% deviation pretty high deviation on interzonal traffic including mode choice the deviation is higher than 120%. Therefore appropriate processing and usage of the data is at least so important as the sample size

Age of challenges Commercialization of BKV Methodology of model building Survey technique
