Build an OD-pair validation table for MPD, adjusted, and benchmark flows

Source: R/validate_flows.R
validate_flow_pairs.Rd

Joins adjusted-flow output to benchmark OD flows and returns a tidy table with original MPD flow, adjusted flow, benchmark flow, and residual-style difference columns. This complements validate_flow_overall(), which summarizes method-level fit, by exposing OD-level differences directly. For richer residual diagnostics (absolute residuals, percentage residuals, improvement flags, and a top-worst table), use validate_flow_residuals().

Retained for backwards compatibility. New code should prefer validate_flow_pairs().

Usage

validate_flow_pairs(
  adj_df,
  benchmark_od_df,
  flow_col_mpd = "flow",
  flow_col_adj = "flow_adj",
  flow_col_bench = "flow"
)

validate_flow_all(...)

Arguments

adj_df

Data frame with at least origin, destination, an MPD flow column (default "flow"), and an adjusted flow column (default "flow_adj"). If present, mpd_source is carried through.

benchmark_od_df

Data frame with at least origin, destination, and a benchmark flow column (default "flow").

flow_col_mpd

Name of MPD flow column in adj_df. Default "flow".

flow_col_adj

Name of adjusted flow column in adj_df. Default "flow_adj".

flow_col_bench

Name of benchmark flow column in benchmark_od_df. Default "flow".

...

Arguments passed to validate_flow_pairs().

Value

A tibble with columns:

  • origin, destination (and mpd_source if present),

  • mpd_flow,

  • benchmark_flow,

  • adj_flow,

  • diff_mpd_benchmark = mpd_flow - benchmark_flow,

  • diff_mpd_adj = mpd_flow - adj_flow,

  • diff_adj_benchmark = adj_flow - benchmark_flow.
