opentripplanner 0.5.2

  • Fixed bug in otp_isochrone when using fromID
  • Slightly faster routing with large batches
  • More mode choices in otp_plan and otp_isochrone

opentripplanner 0.5.1

  • Updated dependency on purrr to require >= 1.0.0
  • Fixed bug in otp_plan when using toID with thanks to @temporalista

opentripplanner 0.5.0

Version 0.5.0 is a significant rewrite of the package focusing on substantially faster routing. The package has moved from using multiple R workers requesting and parsing results from OTP to a two stage process. Stage 1 uses curl to send asynchronous requests to OTP. This stage should be as fast as OTP, and supports OTP's limit of 1.25x the number of cores. Stage 2 parses the JSON and converts it into a form usable in R. The parsing currently uses a single thread, but has been optimised and can now parse around 700-800 routes/second which is faster than OTP at around 40-50 routes/second/core.

Overall the new process is 3-4 times faster than v0.4.0 and uses less memory. Future development may add mulitcore support to the parsing stage for further speed improvements.

Breaking Changes

  • surfaceID returned from otp_make_surface is now a list of lists to allow multiple inputs/outputs
  • removed legacy support for old version of R (<4.0) that don't support RcppSimdJson for older versions of R use version 0.2.3
  • Some columns returned by otp_plan have changed names. The names now start with "leg_" to show they are leg specific variables e.g. "mode" has become "leg_mode"

Other Changes

  • removed dependency on raster and rgdal replaced with terra
  • replaced multi-core routeing with asynchronous requests using curl resulting in faster routing and lower resource usage
  • remove pbapply dependency replaced with progressr
  • remove dependency on lubridate
  • default ncores argument changed from 1 to round(parallel::detectCores() * 1.25) - 1
  • Typos fixed in documentation
  • Support for OTP 2.2 and Java 17

opentripplanner 0.4.0

  • Fix broken or moved URLs
  • tibble moved from imports to suggests
  • Support for OTP 2.0
  • Support for analyst features in OTP 1.x with new functions
  • Support for s2 features in the sf package

opentripplanner 0.3.2

  • Fix a bug with parsing fare data
  • Fix bug with latest version of Java defaulting to 32Bit even when 64bit is available.
  • Added more try() functions to reduce risk of crashes in large scale batch routing
  • Added flag64bit argument to otp_build_graph() and otp_setup()
  • Added quiet argument to otp_build_graph()
  • Updated the Known Issues Vignette
  • reduce initial wait time for otp_setup() from 60 seconds to 30 seconds
  • switch to OTP 1.5.0 as default version in otp_dl_jar()

opentripplanner 0.3.1

Limited support for version of R than can't install RcppSimdJson

opentripplanner 0.3.0

Note that this version makes minor changes to how results are returned, for example column order. These changes are due to the new json parser and should not affect the overall results but may affect any dependent code.

  • Significant refactor of code giving up to 50% reduction in routing time
  • replaced dplyr with data.table
  • replaced httr with curl
  • replaced many rjson functions with RcppSimdJson equivalents
  • replaced many sf functions with sfheaders equivalents
  • fixed bug in otp_plan when distance_balancing = TRUE
  • fixed bug #69
  • In otp_plan will now return fromPlace and toPlace as the first two columns
  • In otp_plan set get_elevation = FALSE as default this boosts performance
  • Fixed bug in distance_balancing that gave sub-optimal balancing
  • When distance_balancing = TRUE zero distance routes will not be found, as OTP will reject these in any case, this saves time with no impact on results.

opentripplanner 0.2.3.0

  • Added distance_balancing argument to otp_plan gives a small performance boost to multicore routing
  • Added get_elevation argument to otp_plan default TRUE, when FALSE returns XY coordinates rather than XYZ coordinates and gives a 4% performance boost.
  • Removed helper code for dplyr::bind_rows as no longer required for dplyr 1.0.0

opentripplanner 0.2.2.0

  • Changes to support dplyr 1.0.0, package now needs vctrs 0.3.1
  • Added timezone support to otp_connect, otp_plan, and otp_isochrone fixing issue #54, see docs for details.
  • Added quiet argument to otp_dl_jar and otp_dl_demo
  • Fixed error in advanced features vignette, issue #57
  • Switch from dplyr to data.table, issue #60

opentripplanner 0.2.1.0

  • Batch isochrones support added
  • Fix bug in correct_distances() when input is of length <= 2 or the distances never decrease
  • Fix bug in polyline2linestring() when elevation is length <= 2
  • New input argument to otp_plan() and otp_isochrone routingOptions this allows support for many more routing options to be set. Arguments walkReluctance, transferPenalty, and minTransferTime have been removed and replaced with routingOptions.
  • New functions otp_routing_options(), otp_validate_routing_options(), otp_check_java()
  • New data for internal package checking
  • Added support of the UK way property set (for OTP 1.5)

opentripplanner 0.2.0.8

  • Disabled CRAN tests that fail on solaris OS, due to different wording of error messages

opentripplanner 0.2.0.6

  • Fixed bug where routing fails due to missing fare data

opentripplanner 0.2.0.4

  • Added a NEWS.md file to track changes to the package.
  • Fixed CRAN test error on certain OS
  • Added CRAN badges

opentripplanner 0.2.0.3

  • First CRAN release

opentripplanner 0.2.0.0

  • Release peer-reviewed by ROpenSci
