dump_ISTDM_shapefile: Transform Cube assignment results in ESRI shapefile to data...

In rickdonnelly/pcvmodr: Portable version of Oregon TLUMIP Commercial Vehicle (CV) model

Description

Transform Cube assignment results in ESRI shapefile to data frame

Usage

dump_ISTDM_shapefile(shapefile, period_label, districts_def,
  areatypes = c("CBD", "Urban", "Rural"), combine.directions = TRUE,
  count.direction = "two-way")

Arguments

shapefile	Data frame containing the contents of the dBASE (.dbf) file created by Cube to export loaded network (traffic assignment) results. Alternatively a string that contains a fully qualified filename (i.e., including full path information) can be supplied, which the function will preprocess before proceeding.
period_label	String denoting the period of the day that the data in 'shapefile' represents. This field will be added to the data frame.
districts_def	Data frame containing a 'DistrictID' for each combination of 'A' and 'B' in 'shapefile'.
areatypes	A list of area type descriptions whose position in the list correspond to integer values of 'AT' in 'shapefile',
combine.directions	Boolean variable denoting whether data for both directions of two-day directional links will be combined to create a single bidirectional link record (defaults to TRUE)
count.direction	String denoting whether the daily counts coded in the 'shapefile' are one-way or two-way (bidirectional) counts (defauls to 'two-way')

Details

This function converts loaded network data included in a dBASE (.dbf) file to those required for post-assignment summaries. The format is specific to the Idaho statewide travel model. A data frame is returned that includes variables that will be used in subsequent analyses.

Examples

assignment_results <- dump_ISTDM_shapefile(shapefileFN, "AM",
  district_definitions, c("CBD", "Urban", "Rural"), TRUE, "two-way")
