Agenda

• Travel over 50 miles a neglected area of policy

• Significant proportion of all CO2 emissions

• Lots of modal-specific policy – rail, aviation, strategic road networks…are they linked up?

• Unexpected things happening – explosive growth of rail travel; road traffic much less fast, but congestion growing; domestic aviation grows (but less to Heathrow)

• ITC commissioned research to explore

• What is long distance travel about? What are the patterns?

• What are the drivers of travel and what can influence it?

• How might this change with different policy scenarios?

Introduction

Agenda

• ITC commissioned Professor Joyce Dargay, Leeds ITS, to construct 4-mode aggregate demand model, to back-cast known travel trends to 1996 and forecast forward to 2030

• Report completed, to be published with ITC covering report January 2010

• Thanks to Joyce Dargay for her significant piece of research

• ITC is very grateful to core sponsors Go-Ahead, Stagecoach and Arriva, and to project sponsors Department for Transport, Rees Jeffreys Road Fund, and Network Rail

• Grateful to David Bayliss for chairing the discussion panel, and to Joyce Dargay for joining us to give further insights into the research

Patterns of long distance domestic travel

Key points

• one third of all travel is over 50 miles

• the car dominates with nearly 80% of travel, rail accounts for 12%, coach and air share 10%

• car dominates for all journey purposes; rail strong for commuting and VFR; rail and air significant for business; coach significant for holidays and leisure

• car travel seems to have flatlined in the last few years, with rail continuing to grow

• 70% of all long distance travel is for holidays, leisure and VFR; business 20%, commuting 10%

• generally balanced between <150 miles and >150 miles; car journeys tend to be shorter

The drivers of long distance travel

Elasticities

• income elasticity of 0.5 means that a 10% change in income will generate a 5% change in long distance travel

• price elasticity of -0.3 means a 10% increase in cost or fares will cause a 3% drop in demand

• cross-elasticity – the impact on (eg) rail travel of a particular change in travel times by car

• cross-elasticity of 1 of rail travel w.r.t. car travel time means a 5% worsening of car travel times will produce an increase in rail travel of 5%. But don’t forget the effect of relative scale.

Page 19: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

19

The drivers of long distance travel

Deriving and interpreting elasticity estimates

• income – short and long run

• demographic and geographic factors

• own and cross elasticities – price and time

The drivers of long distance travel

Income elasticities

• car – less than 0.5 Similar across journey purposes, slightly higher for VFR, higher for longer journeys

• rail – average under 1 But much higher for business and commuting, similar to car for other journey purposes

• coach – unresponsive to income except for longer distance leisure and VFR

• air – about 1.5 for all journey purposes - similar to rail for business

• as income grows, very different patterns of travel growth

Page 23: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

23

The drivers of long distance travel

Demographic and geographical factors

long distance travel analysed by

• household income, gender, age, employment status

• Region of residence, size-scale of municipality or rural

• number of adults in household, whether children, whether main driver of company car

• type of residence, length of residence

Separate models for each of four modes, five purposes and two journey lengths, and the forty in combination

Page 24: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

24

The drivers of long distance travel

Demographic and geographical factors

• overall income elasticity 0.42

• longer distance travel more for men than for women

• more for those under 60 vs over 60

• more for employed/students than for unemployed/retired

• more for those with company cars

• declines with longevity at current residence

Page 25: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

25

The drivers of long distance travel

Demographic and geographical factors

• those in the South West and East Midlands travel more, and those in the WM and northern regions travel less than average

• long distance travel increases as size of municipality decreases, greatest for those in rural areas

• the larger the household the less the per capita long distance travel, and least in families with children

• greater for those living in detached houses....!

Page 26: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

26

The drivers of long distance travel

Own cost/price and time elasticities – long run

• car: cost elasticities -0.3 to -0.8, more for holiday/leisure

• rail: around -0.5 for business and commuting; -1.0 to -1.6 for holiday/leisure/VFR

• coach: -0.8 to -1.0

• air: -0.4 for commuting; around -1.0 for all other

• car: own time elasticities: -1 to > -2 generally; -2.5 for more distant holidays

• rail: -0.5 to -0.75 for commuting; -1.5 to 3.0 for all other

• coach: -1.3 to -1.75

• air: around -0.5 across all purposes

Page 27: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

27

The drivers of long distance travel

Significant cross elasticities – cost/price and time• for business travel: ~ 0.2 c/e to rail w.r.t. car travel cost

• for commuting: ~ 0.2 c/e to rail w.r.t. car travel cost for <150 miles

• for holiday: 0.4 to 0.8 c/e to rail w.r.t. car travel cost

• for leisure and VFR: 0.2 to 0.4 c/e to rail and coach w.r.t. car travel cost

• for business travel: ~1 c/e to rail w.r.t. car travel time

• for commuting: ~0.5 c/e to rail and air w.r.t. car travel time

• for holiday: ~1.5 c/e to rail and ~0.5 to coach w.r.t. car travel time

• for leisure and VFR: 0.7 to 1.0 to rail and coach w.r.t. car travel time; ~1 to coach w.r.t. rail travel time

Page 28: 1 Long Distance Travel in GB some insights and forecasts David Quarmby CBE Member and former Chairman, Independent Transport Commission Transport Planning

28

The drivers of long distance travel

So what does this mean for the drivers of long distance travel by each mode?

• by car: income has a moderate effect, as does the cost of motoring. But worsening of travel times does have a significant impact, especially for longer distance holidays, and does divert demand to rail for business travel, and to rail and (less so) to coach for holidays

• by rail: income has a major effect on business and commuting, and a strong effect on other journey purposes; fares changes have a moderate effect on business and commuting, but a major effect on holiday/leisure/VFR; changes in travel time affect rail similarly. Switching to other modes is modest or non-existent

• by coach: travel unaffected by income. Coach fares and travel times have significant effect on demand. Switching to other modes non-existent

• by air: income has a major effect for all purposes; price elasticity moderate for commuting, high for all other purposes; moderate switching between air (proportionately) and car and rail as their travel times change

Agenda

• On reasonable base case assumptions we forecast a 34% increase in long distance travel – 125% by air, 35% by rail, 30% by car and 25% by coach – mostly income driven

• Universal road charging cuts car demand by 10%, but rail demand is very sensitive (48% growth vs 35% growth)

• Variations in car fuel efficiency (and cost) affect car travel by + 20%, and a 1% rise in motoring costs especially

• Air travel very sensitive to APD increases, and fares variations – but still >100% growth for any of the scenarios

• Coach travel affected by rail pricing and motoring costs

• lower GDP growth (1.25%) halves the travel growth
