An inland rail route between Melbourne and Brisbane? The North-South rail corridor study 14 June 2007 BTRE Transport Colloquium
Structure of presentation • Introduction • Total freight market • Mode choice modelling • Access prices • Passenger market modelling • Project outcomes • Areas of future research
The task • Background: freight growth, Auslink upgrades, lobbying for inland rail route • To consider options for the Melbourne - Brisbane rail corridor over the next 25 years • Consortium: • Ernst and Young (project leader, financial anaylsis) • Hyder (route options, other infrastructure, environmental) • ACIL Tasman (demand, access prices)
Analytical approach • Identify current total freight market • Forecast growth in total freight market for 25 years • Determine current mode shares • Estimate mode shares over 25 years and their sensitivity to changing service quality • Estimate rail freight over 25 years • Integrate with other models in consortium
Analysis of base (2004) • Origin - destination tonnages by commodity • Data from rail operators, BTRE, ABS, FDF • FreightSim for forecasting model. Structure: production, imports, consumption • ACIL Tasman model of freight inducement effects
Drivers of future demand • GDP growth (production, imports, consumption) • Transport freight to GDP growth ratio • Growth of industrial concentration • Growth of agricultural production • Growth of imports, service sector • Scenarios • High/medium/low GDP • Growth transport/GDP ratio
New East Coast demand with an inland route • Coal in southern QLD, northern NSW • But questions about which route, which port • Little else • Mainly a through route with a stop at Parkes
Freight diversion – northern NSW • 27% of grain from Northern Plains to Brisbane from Newcastle • 50% of cotton from Northern Plains to Brisbane from Port Botany • Brisbane-Perth freight via Parkes • No other material freight diversion
Road, rail, sea or air ? • Current market shares by mode • Drivers of mode choice • Sydney • Convenient departures • Logit model • Results
2004 snapshot • Current Rail mode shares • Melbourne-Brisbane ~30% • Melbourne-Sydney ~7% • Sydney-Brisbane ~11% • Rail more price competitive on longer routes, less on shorter routes because of PUD time and costs • Rail outperformed by road in service quality
Explanatory variables • Price • $/tonne (but complexities) • Reliability • within 15 minutes of scheduled arrival time • Availability • % of times the freight carrier is available within an hour of customers’ preferred time • Survey: • how does demand for rail (at the expense of road) vary with changes in price, reliability, availability?
Mode choice • Logit model to predict modal shares • Calibrated to explain current shares • Forecast changes based on expected route characteristics • Price (incl fuel price, driver shortage) • Reliability following AusLink upgrade • Availability following AusLink upgrade • Key parameters estimated from • Surveys • Econometric analysis of past data
Logit model • Gives probability (%) of freight forwarder choosing mode n • Simple logit (two modes) formula • Where U is utility of using rail or road • linear utility functions: constant + variable1 x coefficient1 + etc
Logit model – hierarchical structure • Logit model can be used at each level of the freight decision making process • Nested logit useful for inland rail analysis
Values/inputs to use in the model • Current estimates of road and rail performance and mode share were derived from • Rail operators, BTRE, ARTC, surveys • Future estimates of road and rail performance were derived from • ARTC, BTRE, ACIL Tasman, Hyder, freight operators • Standalone road and rail freight pricing model developed • Access prices, fuel costs, labour
Scenarios • Case A (reference), Case B (high rail), Case C (low rail) • Fuel price assumptions • Road and rail labour cost assumptions
Elasticities and coefficients • Choice elasticities were estimated • From these – coefficients were calculated
Testing of the logit model • Observed performance (Melb-Perth 2000) • Logit modelling of same input variables
Financial and economic results • Summary of results • Interpretation of results • Coastal route: problems and solutions • Inland route: problems and solutions Full report including Ernst & Young and Hyder chapters not covered here, on www.aciltasman.com.au
