Minimum requirements for a PCT at any place

[temospena]

This is an open issue to discuss the "Minimum requirements for a PCT at any place".

Comments, approaches, and suggestions are welcome!

Thanks for the introduction to the PCT this morning. I didn't quite get how we can capture intrazonal trips (as was rightly mentioned this morning that many trips on bicycle will fall within the same zone). What approaches have you used to quantify the potential of these trips? (in the PCT or in other approaches)

Good hack topic I think @suzannemaas - especially in areas with large zones.

@joeytalbot was interested in this I think.

Minimum requirements for a PCT

Zones

Divide the city into zones
Census

• Where people live and work
  Divide in our own zones?
• Package zonebuilder [url()]

which zoom level?

As long as you can walk or cycle between 2 zones?
random point for O and D in the same zone?
- what about if 50% trips are made in the same zone?

#And use always the lower level, or aggregate?
not too detailed
computation intensive

OD data at those zones level

cycling
car

Route options

Journey planners, such as cycliestreets algorithm
Routing services - route_fun = cyclestreets::journey (see other route_fun avaliable)

Road network

From OSM maps? even with poor quality

Use PCT with our own spatial road network?

and with our own cycling route functions?
