How the PCT works

---

The first prototype of the PCT

• 1st prototype: Hackathon at ODI Leeds in February 2015

• We identifying key routes and mapped them

• For description of aims, see Lovelace et al. (2017)

knitr::include_graphics("https://raw.githubusercontent.com/npct/pct-team/master/figures/early.png")

---

• Launched in 2017 with the Cycling and Walking Investment Strategy (CWIS)

Photo: demo of the PCT to Secretary of State for Transport (March 2017)

The important of open access models

The PCT in 2020

• Now the go-to tool for strategic cycle network planning in England and Wales, used by most local authorities with cycling plans (source).

.pull-left[

Geographic levels in the PCT

• Generate and analyse route networks for transport planning with reference to:
  • Zones
  • Origin-destination (OD) data
  • Geographic desire lines
  • Route allocation using different routing services
  • Route network generation and analysis ]

See these levels at www.pct.bike

Uses of the PCT

• Visioning
• Planning strategic cycle networks
• Identifying corridors with high latent demand

Uses that were not initially planned

• Pop-up cycleway planning
• LTN planning?

Deploying in new contexts

• Requires survey based or synthetic OD data, to be processed by software developed at Leeds r Citep(my_bib, "lovelace_stplanr:_2018", .opts = list(cite.style = "authoryear"))
• For mor on methods, see the transport chapter (available free online) r Citep(my_bib, "lovelace_geocomputation_2019", .opts = list(cite.style = "authoryear"))
• Can also be used for specific contexts (e.g. cycling to school, cycling to public transport) r Citep(my_bib, "goodman_scenarios_2019", .opts = list(cite.style = "authoryear"))

For further info, see the training materials at itsleeds.github.io

Many use cases on the PCT website: pct.bike/manual.html

• Case studies of over a dozen areas, including Greater Manchester and Herefordshire in the manual

New possibilities in the PCT approach

See web.tecnico.ulisboa.pt for interactive map

Estimating change in exposure

Tackling denominator neglect

---

Estimating safety levels in KSI/bkm at high resolution

---

Estimating health benefits of cycling uptake with the PCT

• The PCT uses a modified version of the HEAT methodology to calculate health benefits of scenarios of change
• Based on the DfT's TAG methodology
• The scenarios are what if scenarios not forecasts
• See the PCT manual for further information: pct.bike/manual.html
• See the DfT's AMAT tool also
