Travel Behavior and mode choicein the Czech Republic Markéta Braun Kohlová Charles University of Prague, Environment Centre Czech Republic
Structure of the presentation • I) CUEC research activities in transport • II) Modal choice modelling • III) Potential demand for cycling infrastructure • IV) Future research
PART I - CUEC Research Activities in Transport • Estimation of Cost Functions of public transport providers (for welfare analysis of regulation in cities) • Quantification of external costs • Regulation analysis • Analyses of the household demand systems • Travel behavior – modal choice
PART I - CUEC Research Activities in Transport Ad1. Estimation of Cost Functions of public transport providers (for welfare analysis of regulation in cities) • the cost function parameters • parameters of scale effects Ad2. Quantification of external costs • ExternE methodology Ad3. Regulation analysis • air-pollution regulation in Czech cities • CBA (cycling infrastructure, Pilsen) Brůhová-Foltýnová, Braun Kohlová, 2006
PART I - CUEC Research Activities in Transport Ad4. Analyses of the household demand systems • The Household Budget Surveys (CSÚ) • N=3,000; quota sampling; quazi panel • 13 household groups • social status> farmers, retired, single or pair with / without children determining transport use • municipality size> (up to 2.000, 2.000-20.000, above 20.000) determining transport mode availability Estimates: • Own-price, cross-price and income elasticities (for fuels consumption, public transport use) • Distributional effect assessment for motor fuel taxation Brůha, Ščasný, AERE, 2006
Selected Results – expenditures (%) • Elasticities for income deciles and 9 social groups - for motor fuels only • 1) own price el.: 2) Income el.: • - average for deciles:- 0.41 - declines with income • - for social group: - 0.65 - average for decile:+ 1.07 • - the highest for pensioners:- 0.82 - for social group:+ 0.6Ščasný-Brůha (2003) • Brůha-Ščasný (2004) • Uncompensated price elasticities: Fuel price Public transport fares • Fuel use – urban - 1.04 0.28 • Fuel use – rural - 0.4 0.03 • Public Transport Use 0.3 - 0.65
Modal split in Pilsen and other European Cities Source: Informace o dopravě v Plzni 1997 - 2003, ECI 2003
Case study: survey City of Pilsen Intra-urban travel only Population: 155 000 Adults (18+) Quota sample: 763 Working days only Year: 2005
Travel behavior– personal (individual) Dependent variables: • binary choice models 1) Car ownership 2) Modal Choice = a mean chosen on experimental working (included in the chain of the trips) - Car use (driver, passenger) - Bicycle use
Attitudes Measurement • General statements (26) • Agreement on the 5 point Likert-scale • Factor Analysis (4 extracted): I) BIKE – neither convenient nor appropriate II) PUBLIC TRANSPORT – convenient for all the purposes III) CAR – status symbol and necessity IV) SPEED TOLERANCE
ENVIRONMENTAL CONCERN INDEX Statements (6): reported behaviour seriousness of environmental threat • RESULTS: - - public transport + walk - - car - Ø - bike
PART III – Estimate of a potential demand for cycling infrastructure • For the CBA of cycling infrastructure in Pilsen • Stated preferences design = willingness to replace the current means of transport with bicycle
Identification of more frequent cyclists… if cycling infrastructure improved
Demand for cycling -estimate of its potential change Current transportation behavior • Diaries: • All trips (on previous working day) • Purpose, distance, duration, means of transport Demand = aggregate of population preferences stated as a potential choice of means of transport • Quantified: persons, kms, minutes • For current prices • For each trip purpose separately
PART IV – Future reasearch • Modal choice – data from middle sized and small cities and Prague • residential characteristics • suburban commuting • explain differences in modal split between cities • Impact of new constructed infrastructure on modal choice (in-depth interview) • Validation of SP method • Regulation analysis • Economic model of travel behavior (mode specific costs) • Analysis of household demand system
The research project has been supported by the grant of the Ministry of Transport No. 1F43E/045/210 „CYCLE 21 – Analysis of Demand for Building of cycling infrastructure“ and the grant of the Ministry of Transport No. 24/2006-430-OPI/3 supported from the Operational Program „Infrastructure“ - Priority 2 (2.4) The support is gratefully acknowledged.
