pseudohouseholds: Generating Representative Points on Roads in Regions for Travel Analyses3 years ago
Summary | What are pseudohouseholds? | The pseudohouseholds package | The algorithm for creating pseudohouseholds | If the region is unpopulated, optionally return a default point. | Find road segments intersecting or near the region | Create initial points by sampling along the road segments | Create candidate PHHs beside the road network | Keep only candidates within the region | (If necessary) If no valid points are returned, sample radially around our on-street points | (Optionally) Ensure our PHHs have a minimum population | (Optionally) Remove candidates that are too close to others | Distribute regional population among PHHs | Considerations | The final number of PHHs may be more or less than you expect. | Any input roads may receive PHHs, so ensure only habitable roads are used as inputs. | PHHs do not correspond directly to dwellings, and should only be used as a proxy to "smooth out" populations for analysis. | Details | The variable phh_type | The default point
