Introductory comments

Context (see the 'CWIS' report)

  • 2 years in the making, the PCT is now part of the Cycling and Walking Infrastructure Strategy (CWIS)
  • Mentioned in the forword of this legally binding document
  • Being used by dozens of local authorities to design strategic cycling networks

The propensity to cycle tool method

Demonstration

A spatial interaction model (Lovelace and Ellison, in press)

library(stplanr)
## Loading required package: sp
cents$pop = 1:nrow(cents)
plot(cents, cex = cents$pop)

The radiation model (Simini et al. 2012)

flow_est = od_radiation(p = cents, pop_var = "pop")
plot(flow_est, lwd = flow_est$flow)

For England we have OD data

For Spain we do not - so model it

Discussion

Technical issues

  • For scalability generalisability is vital
  • software engineering/compsci approach
  • But political leadership vital

Wider issues

  • Links with the Cycling Infrastructure Prioritisation Toolkit (CyIPT)
  • How to institutionalise the open (data, science) approach
  • Citizen science / crowd funded add-ons
  • Next case study cities?
