Calculate accessibility change from new cycling projects

This code calculates the change in destination accessibility for each origin in Toronto as a result of an input list of cycling infrastructure projects.

Inputs:

• A list of projects -- a list of integer IDs for projects that correspond to the arterial road segments in proj2artid, i.e. project 0 is the 0th indexed element in proj2artid. Alternatively projects are listed as network edges in args['projects'].
• args.pkl -- object containing:
  • destination values for each DA (indexed by centroid node ID)
    • graph object for full city network (G) and reachable with current infrastructure (G_curr)

Returns:

• change in destination accessibility for each origin, mapped to DAid in a csv

Usage:

Test project set - 10 km city-wide budget, from seed 38 - data/new_projects.csv
