v2.3.0

Major changes

• New function build_network() to replace setup_r5(), which is being deprecated. Idiomatically r5r_core is now r5r_network.
• New function arrival_travel_time_matrix() to calculate travel time matrix between origin destination pairs considering the time of arrival, instead of a depature time. Closes #291
• We have now implemented a reverse search optimization for direct transport modes (walking and cycling) in the functions travel_time_matrix(), expanded_travel_time_matrix() and arrival_travel_time_matrix(). In practice, this means that these functions are now much faster when there are multiple origins to few destinations but only when there is no elevation .tif file in the data path. Closes #450
• All routing and accessibility functions in r5r have new parameters new_carspeeds, carspeed_scale and new_lts which allow one to use custom car speeds and LTS levels for cycling. These parameters provide convient and efficient ways to build different scenarios of traffic congestion, road closure and interventions in cycling infrastructure. Closes #289

Minor changes

• The routable transport network built with build_network() and setup_r5() now have their own class "r5r_network", making the package more consistent and safer from errors #472.
• Routing properties within r5r jar (aka little jar) are reset to default after a routing execution #453
• Less cluttering messages in r5r dialogue. Removed logback startup messages. Verbose=F now completly silences java output. Verbose=T only reports messages up to INFO level as opposed to up to DEBUG #456.
• Removed date from r5r-log. You no longer have to delete the previous day's log! #456
• Improved warning and error messages.
• r5r developers can now set options(r5r.r5jar=...) to use a local JAR instead of the R5 jar downloaded by r5r.

Bug fixes

• Fixed a bug where network_settings.json wasn't showing the right version numbers #459. Version number now dynamically updated #456.

v2.2.0

Major changes

• r5r now uses the latest version of R5 V7.4. Closed #436
• The detailed_itineraries() now has a new parameter osm_link_ids. A logical. Whether the output should include the additional columns with the OSM ids of the road segments used along the trip geometry Defaults to FALSE. Closes issues #298

Minor changes

• r5r now throws an informative error message when the geographic extent of input data exceeds limit of 975000 km2. Closes issues #389, #405, #406, #407, #412 and #421. Thanks to PR #426 by Alex Magnus.
• removed JRI dependency in r5r little jar. This helps debugging issues in Java without the need of using R. The side effect is that r5r now creates an r5rlog file in the data path.

Bug fixes

• Fixed a bug that prevented the package to check the availability of transit services in specific days when there is no service at all.
• Fixed a bug in the isochrone function that was throwing false error message regarding cutoff being too short. Closed #434 and #433

r5r v2.1.0

Minor changes

• The isochrone() function has a new boolean parameter polygon_output that allows users to choose whether the output should be a polygon- or line-based isochrone. Closed #382
• When using public transit modes, the package now automatically detects whether there are any transit services operation on the seleced departure date. If there are no services, the package will return an error message. Closed #326

r5r v2.0

Breaking changes

• r5r uses now JDK 21 or higher (Breaking changes). Closed #350.
• r5r now uses the latest version of R5 V7.1. Closed #350

Major changes

• r5r now stores R5 Jar file at user dir using tools::R_user_dir()
• New function r5r_cache() to manage the cache of the R5 Jar file.
• By using the JDK 21, this version of r5r also fixed an incompatibility with MAC ARM processors. Closed #315

Minor changes

• In the accessibility() function, the value of max_trip_duration is now capped by the max value passed to the cutoffs parameter. Closes #342.
• Updated documentation of parameter max_walk_time to make it clear that in walk-only trips, whenever max_walk_time differs from max_trip_duration, the lowest value is considered. Closes #353
• Updated documentation of parameter max_bike_time to make it clear that in bicycle-only trips, whenever max_bike_time differs from max_trip_duration, the lowest value is considered. Closes #353
• Improved documentation of parameter suboptimal_minutes in the detailed_itineraries() function.
• Updated the vignette on time window to explain how this parameter behaves when used in the detailed_itineraries() function.

Bug Fixes

• Fixed bug that prevented the use the output_dir parameter in the detailed_itineraries(all_to_all = TRUE) function. Closes #327 with a contribution (PR #354) from Luyu Liu.
• Fixed bug that prevented detailed_itineraries from working with frequency-based GTFS feeds. It should ONLY work with frequency-based GTFS feeds.

r5r v1.1.0

r5r v1.1.0

Major changes

• New isochrone()function. Closes #123, and addresses requrests in issues #164 and #328.
• New vignette about calculating / visualizing isochrones with r5r.
• New vignette with responses to frequently asked questions (FAQ) from r5r users.

Minor changes

• The default value of time_window is not set to 10 minutes in all functions to avoid weird results reported upstream in R5. Closes #342.
• Removed any mention to percentiles parameter in the expanded_travel_time_matrix() because this function does not expose this parameter to users. Closes #343.
• Updated vignette on calculating / visualizing accessibility with r5r.

r5r v1.0.1

Bug fixes

• Updated to R5 version 6.9. This fixed a few bugs upstream, one of which often prevented users to build a network using cropped OSM data. Closes #325.

v1.0.0

r5r v1.0.0

Breaking changes

• Replaced max_walk_dist and max_bike_dist parameters with max_walk_time and max_bike_time to better align with R5 inputs. Closes #273.
• r5r now uses R5's native elevation weighting for walking and cycling impedance functions. As a result r5r does not have raster or rgdal package dependencies anymore. Closes #243 and #233.
• Parameters breakdown and breakdown_stat in travel_time_matrix() were removed. New function expanded_travel_time_matrix() should be used to retrieve detailed information of travel time matrices.
• r5rnow throws an error if users simultaneously pass more than one of the following modes c('WALK','CAR','BICYCLE') to the transport_mode parameter. This is because these modes are understood as mutually exclusive.
• Function setup_r5() no longer has a version parameter.

New functions

• New function expanded_travel_time_matrix() to calculate minute-by-minute travel times between origin destination pairs and get additional information on public transport routes, number of transfers, and total access, waiting, in-vehicle and transfer times.
• New function pareto_frontier() to compute of travel time and monetary cost Pareto frontier.
• New function r5r_sitrep() to generate an r5r situation report to help debug code errors
• New functions to account for monetary costs:
  • setup_fare_structure() to setup a fare structure to calculate the monetary costs of trips
  • read_fare_structure() to read a fare structure object from a file
  • write_fare_structure() to write a fare structure object to disk

Major changes

• Now using R5 latest version 6.8.
• The detailed_itineraries() has been substantially improved. The new vesion is faster than previous ones. It also includes new parameters listed below. Closes #265.
  • New time_window parameter
  • New suboptimal_minutes parameter, which extends the search space and returns a larger number of trips beyond the fastest ones;
  • Support for fare calculator and new max_fare parameter;
  • Routing in frequencies GFTS, including support for Monte Carlo draws
• New parameter draws_per_minute to travel_time_matrix(), accessibility() and pareto_frontier() functions. Closes #230.
• New parameter output_dir to all routing functions, which can be used to specify a directory in which the results should be saved as .csv files (one file for each origin). This parameter is particularly useful when running estimates on memory-constrained settings, because writing the results to disk prevents R5 from storing them in memory.
• The accessibility estimates from accessibility() are now of returned as doubles / class numeric, except when using a step decay function. Closes #235.
• The detailed_itineraries() function has a new parameter all_to_all, which allows users to set whether they want to query routes between all origins to all destinations (all_to_all = TRUE) or to query routes between the 1st origin to the 1st destination, then the 2nd origin to the 2nd destination, and so on (all_to_all = FALSE, the default). Closes #224.

Minor changes

• Package documentation has been extensively updated and expanded.
• Improved documentation of the cutoffs parameter in accessibility(), clarifying the function only accepts up to 12 cutoff values. Closes #216.
• Improved documentation of the percentiles parameter in accessibility() and travel_time_matrix(), clarifying these function only accepts up to 5 values. Closes #246.
• r5r now downloads R5 Jar directly from Conveyal's github, making the package more stable. Closes #226.
• All functions now use verbose = FALSE and progress = FALSE by default.
• Routing functions now require users to be non-ambiguous when specifying the modes, raising errors when it cannot disambiguate them. This new behaviour replaces the old one, in which the functions could end up trying to "guess" which mode was to be used in some edge cases.
• Information on bicycle 'level of traffic stress' is now added to the output of street_network_to_sf(). Closes #251.
• New columns with info on population, schools and jobs in the example data sets for Sao Paulo and Porto Alegre

Bug fixes

• Fixed bug that transit_network_to_sf() generated some routes with invalid geometries. Closes #256.
• Fixed bug that prevented setup_r5(path, overwrite = TRUE) to work.

v0.7.1

Minor change

• Replaced the akima package with interp package in r5r Suggests, as requested by CRAN.

v0.7.0

r5r v0.7.0

Major changes

• From this version onwards, r5r downloads R5 JAR from github, which provides more stable connection than Ipea server.
• The number of Monte Carlo draws to perform per time window minute when calculating travel time matrices and when estimating accessibility is now set via the r5r.montecarlo_draws option. Defaults to 5. This would mean 300 draws in a 60 minutes time window, for example. The user may also set a custom value using options(r5r.montecarlo_draws = 10L) (in which you substitute 10L by the value you want to set).

Minor changes

• Changed total_time column name to combined_time in travel_time_matrix()
  output, to avoid confusion with travel_time column.

v0.6.0

v0.6.0

Major changes

• Updated R5 to version 6.4. Closes #182.

• Significant performance improvements in all functions, due to a faster method
  for consolidating outputs. Closes #180

• New function transit_network_to_sf(), to extract the public transport network
  from R5 as simple features. Closes #179

• New progress parameter in the accessibility(), travel_time_matrix, and
  detailed_itineraries() functions, to show or hide the progress counter
  indicator. Closes #186

• Created new support function java_to_dt() and removed dependency on the jdx package. Closes #206

• Reduced r5r's internet dependency quite considerably. Internet is now only required to download the latest R5 jar if it hasn't been downloaded before. Closes #197.

• Added two new parameters breakdown and breakdown_stat to the travel_time_matrix(). This allows users to breakdown the travel time information by trip subcomponents (access time, waiting time, traveling time etc). It allows one to extract more information but it makes computation time slower. Closes #194

Minor changes

• New setup_r5() parameter, overwrite, that forces the building of a new network.dat, even if one already exists.
• Improved documentation of parameter departure_datetime to clarify the parameter must be set to local time. Closes #188
• Improved documentation regarding personalized LTS values. Closes #190.
• Improved documentation of transit_network_to_sf() regarding stops that are not snapped to road network. Closes #192.
• Improved documentation of max_walking_dist and max_cycling_dist parameters. Closes #193.
• Started raising an error if the CRS of origins/destinations is not WGS 84. Closes #201.
