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 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).

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 ]

Route networks

u = "https://github.com/ITSLeeds/pct/releases/download/0.5.0/routes_od_data_df_df.Rds"
f = basename(u)
if(!file.exists(f)){
  download.file(u, f)
}
r = readRDS(f)

rnet = stplanr::overline(r, "bicycle")
plot(rnet, lwd = rnet$bicycle / 10)

Cycling uptake

Cycling potential in London under scenarios of change

• Ebike scenario is most ambitious
• Government target can be set to local priorities ]

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"))
