B Street Transport System Simulation Software

Description Usage Arguments Details Value Examples

This function takes a path to a JSON file representing an A/B Street scenario, or an R representation of the JSON in a list, and returns an sf object with the same structure as objects returned by ab_scenario().

1	ab_sf(json)

json

Character string or list representing a JSON file or list that has been read into R and converted to a data frame.

Note: the departure time in seconds is divided by 10000 on conversion to represent seconds, which are easier to work with that 10,000th of a second units.

An sf data frame representing travel behaviour scenarios from, and which can be fed into, A/B Street. Contains the following columns: person (the ID of each agent in the simulation), departure (seconds after midnight of the travel starting), mode (the mode of transport, being Walk, Bike, Transit and Drive), purpose (what the trip was for, e.g. Work), and geometry (a linestring showing the start and end point of the trip/stage).

file_name = system.file("extdata/minimal_scenario2.json", package = "abstr")

json = jsonlite::read_json(file_name, simplifyVector = TRUE)
