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
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
