Creates a basic fare structure that describes how transit fares should be calculated in travel_time_matrix(), expanded_travel_time_matrix(), accessibility() and pareto_frontier(). This fare structure can be manually edited and adjusted to the existing rules in your study area, as long as they stick to some basic premises. Please see fare structure vignette for more information on how the fare structure works: vignette("fare_structure", package = "r5r").

An object to connect with the R5 routing engine, created with setup_r5().


A numeric. A base value used to populate the fare structure.


A string. Describes how fare_types (a classification we created to assign fares to different routes) are distributed among routes. Possible values are MODE, AGENCY and GENERIC. MODE is used when the mode is what determines the price of a route (e.g. if all the buses of a given city cost $5). AGENCY is used when the agency that operates each route is what determines its price (i.e. when two different routes/modes operated by a single agency cost the same; note that you can also use AGENCY_NAME, if the agency_ids listed in your GTFS cannot be easily interpreted). GENERIC is used when all the routes cost the same. Please note that this classification can later be edited to better suit your needs (when, for example, two types of buses cost the same, but one offers discounts after riding the subway and the other one doesn't), but this parameter may save you some work.


Either a path to a .csv file or NULL. When NULL (the default), fare debugging capabilities are disabled - i.e. there's no way to check if the fare calculation is correct. When a path is provided, r5r saves different itineraries and their respective fares to the specified file. How each itinerary is described is controlled by debug_info.


Either a string (when debug_path is a path) or NULL (the default). Doesn't have any effect if debug_path is NULL. When a string, accepts the values MODE, ROUTE and MODE_ROUTE. These values dictates how itinerary information is written to the output. Let's suppose we have an itinerary composed by two transit legs: first a subway leg whose route_id is 001, and then a bus legs whose route_id is 007. If debug_info is MODE, then this itinerary will be described as SUBWAY|BUS. If ROUTE, as 001|007. If MODE_ROUTE, as SUBWAY 001|BUS 007. Please note that the final debug information will contain not only the itineraries that were in fact used in the itineraries returned in travel_time_matrix(), accessibility() and pareto_frontier(), but all the itineraries that R5 checked when calculating the routes. This imposes a performance penalty when tracking debug information (but has the positive effect of returning a larger sample of itineraries, which might help finding some implementation issues on the fare structure).
