  1. The household survey of Budapest and its surroundings The theoretical background and technology of the household survey Zsolt Berki TRANSMANConsulting for Transport System Management 1051 Budapest Hercegprímás u. 10.

  2. 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

  3. Determination of the key drivers of mode choice

  4. Theoretical diagram of mode choice decision making process T => Time K => Cost S => Service

  5. Survey ‘book’ outline

  6. Survey sheet of private homes • semi-proper address • number of inhabitants • home type • conveniences • income category • available transport means

  7. Survey sheet of vehicles • category • age • parking place • ownership • usage frequency • engine size (ccm) • fuel type

  8. Survey sheet of persons • sex • age • activity • educational level • driving licence • pass holding • legitimacy of concessionary fee • employers’ subsidy • Internet, car usage

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

  10. Trip definition

  11. Trip definition - 2

  12. Trip definition - 3

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

  14. 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?

  15. Distribution of communal homes in Budapest • 465 communal home • 43858 tenants (HCSO, 2001) • disproportionate area distribution • concentrated, partly homogeneous transport demand • decisive local role

  16. 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

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

  18. 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

  19. Age of challenges • Commercialization of BKV • Methodology of model building • Survey technique

  20. Thanks for your attention!
