Transcript

  1. Estimating distance decay: for the National Propensity to Cycle Tool

    (NPCT) Robin Lovelace, University of Leeds. Talk at the Institute for Transport Studies (ITS) Slides: speakerdeck.com/robinlovelace
  2. Uses of dd: a few ideas • If we're to

    transition away from fossil fuels, we must use modes that are less energy intensive • Distance decay for sustainable travel modes can tell us what future travel patterns must look like • Characterising travel systems • Especially relevant for active travel • The National Propensity to Cycle Tool (NPCT)
  3. Further work on distance decay • The distance-decay of road

    traffic incidents? • Its use to estimate non-work travel? • Verification of dd parameters using Big Data
