    • Technologies
    • Demography
    • policy demands

some thoughts on content
Some thoughts on content
  • Not too surprisingly content is very similar
    • Asking about rail passes
    • Asking about business travel
  • The great challenges
    • Get at long distance travel in one survey
    • Get at more detailed private vehicle activity
    • Get at variation in week’s travel
on long distance travel
On long distance travel
  • We need a complete trip length distribution 0-1000 miles
  • We need a frequency distribution of what percent of long travel is generated by what percent of pop
  • Survey approaches that can’t do that have limited value
  • What share of travel lies between daily travel and intercity? World Tourism Organization of the UN defines this as = travel outside the “usual” environment
  • Not likely doable in a composite survey!
  • Not clear that it is worth the costs involved!
usa ats 1995
USA: ATS 1995

In US >2000 miles* = 10% of trips & 42% of long trip miles

10% of pop makes 51% of trips

some thoughts on methods
Some thoughts on Methods
  • More Issues; more challenges; as expected
    • Periodicity is a great issue everywhere
    • 5 continuous surveys;
    • 9 others very variable in timing 4,6,10 years!!!
    • Research on decay rates of data needed
  • Advantages of a national register-like sample frame is evident
  • CATI still strong in some places; threatened in others. New techs are a big part of the future
  • NEED TO SHARE OUR EXPERIENCE WITH NEW TOOLS
some thoughts on finance
Some thoughts on Finance
  • A struggle to do surveys
  • A struggle to sustain them
  • Maybe Switzerland is immune? Not really!
  • Do we fail to make the policy case for better information
  • Need research on value of data; B/C

If you think data collection is pricey – consider the cost of ignorance!

some thoughts on institutions
Some thoughts on Institutions
  • Who leads – Who follows: A 3 way challenge
    • Cities/metros?
    • Provinces/States/Regions?
    • National?
  • Now trans-national EU; N. Amer. Surveys?
  • National plus add-ons is strong prospect
    • Canadian variation
    • Other models?
some thoughts on policy
Some thoughts on Policy
  • Things getting very nichie in traditional data
    • e.g., Electric vehicles
    • Some niche modes
    • some niche purposes/activities
    • Some niche applications
  • Other Policies than directly transportation
    • Vehicle Safety
    • Environmental
    • Fuel Use and Efficiency
    • Sustainability
thank you
Thank you!
