PASSENGERS’ CHOICE BETWEEN COMPETING AIRPORTS Radosav Jovanovic Faculty of Transport and Traffic Engineering, University of Belgrade
Introduction • Liberalization of airline regulation – changes to management and planning of airports • Increased competition • Low cost carriers • EU expansion • Necessity of explicit analysis of airport choice determinants
On the paper • A model to predict the distribution of business passengers in a MAS • Case study: E-75 HCAS • Data used: 2001, 2002, 2003 FTTE air passengers surveys at Belgrade a/p, 2001 FTTE survey of Serbia originating passengers departing from Budapest a/p
Background • US MASs, London airport system • Different functional forms and explanatory variables • Usually: MNL, nested logit model • Relevant variables: air fare, flight frequency, airport accessibility (ground access characteristics)
Proposed Airport Demand Allocation Model • Exponential formula to calculate the effects of choice attributes (FF, ATD, AF) on airport attractiveness • Stage 1 – Indifference equation to relate FRk to ATD variable • Stage 2 – To establish a pattern of airport attractiveness alteration in the region observed
Case Study: E – 75 HCAS
Stage 1 Specification • 100 % flight frequency (FF) ~ 15 % of fare • 1 h difference in travel time (ATD) ~ 20-40 % of fare • Linear AF to ATD relationship • Thecompensatingfrequencyratio FRk = a*eb*ATD
Stage 1 Application Example • Trip to Munich • Belgrade versus Budapest airport • 2 vs 7 daily-direct flights (FR=7/2) • 80 kmph average highway speed • 30 minutes border stopping => ATD = 94 min, EAP in Backa Topola (157 km north of Belgrade)
Stage 2 Specification • Input variables: • Daily-direct FFs • ATD • “S”-curve α parameter-how airport’s frequency share affects its market share • Five-sequences procedure to calculate the market share attracted
1. FRk = 1.1025*e0.7392*ATD 2. FFD(k) = FRk * FFC 3. LRFD = FFD / FFD(k) 4. RFD = LRFD / (LRFD + LRFC) 5. PSD = (RFD)α / [(RFD)α + (1 - RFD)α]
Stage 2 Application ExampleAirport Choice of Business Travelers, Munich Trip
Different Scenarios Considered • Nine destinations (MUN, FRA, LON, PAR, AMS, MIL, ZUR, VIE, MOS) • Base case (BC) – current levels of airline services • SC1 – BEG FF+1 • SC2 – BEG FF+1, BUD FF+1 • SC3 – NIS vs BEG distribution (ZUR trip)
Limitations – Possible Improvements • Absence of authentic preference structure of a Serbian air traveler • Credible calibration of the "S"-curve α parameter (origin and/or destination zone specific) • Getting quantitative perceptive scales from qualitative survey data
Conclusions • Sensitivity analysis (predicting FF and ATD changes effects-redistribution) • “What to offer” at or “where to locate” a new airport • To match the aircraft capacity to demand attracted
