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_surfaceis now a list of lists to allow multiple inputs/outputs - removed legacy support for old version of R (<4.0) that don’t support
RcppSimdJsonfor older versions of R use version 0.2.3 - Some columns returned by
otp_planhave 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
rasterandrgdalreplaced withterra - replaced multi-core routeing with asynchronous requests using
curlresulting in faster routing and lower resource usage - remove
pbapplydependency replaced withprogressr - remove dependency on
lubridate - default ncores argument changed from
1toround(parallel::detectCores() * 1.25) - 1 - Typos fixed in documentation
- Support for OTP 2.2 and Java 17
opentripplanner 0.4.0
CRAN release: 2022-01-20
- Fix broken or moved URLs
-
tibblemoved from imports to suggests - Support for OTP 2.0
- Support for analyst features in OTP 1.x with new functions
- Support for
s2features in thesfpackage
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
flag64bitargument tootp_build_graph()andotp_setup() - Added
quietargument tootp_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
CRAN release: 2020-11-09
Limited support for version of R than can’t install RcppSimdJson
opentripplanner 0.3.0
CRAN release: 2020-10-23
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
dplyrwithdata.table - replaced
httrwithcurl - replaced many
rjsonfunctions withRcppSimdJsonequivalents - replaced many
sffunctions withsfheadersequivalents - fixed bug in
otp_planwhendistance_balancing = TRUE - fixed bug #69
- In
otp_planwill now returnfromPlaceandtoPlaceas the first two columns - In
otp_plansetget_elevation = FALSEas default this boosts performance - Fixed bug in
distance_balancingthat gave sub-optimal balancing - When
distance_balancing = TRUEzero 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
CRAN release: 2020-06-09
- Added
distance_balancingargument tootp_plangives a small performance boost to multicore routing - Added
get_elevationargument tootp_plandefault TRUE, when FALSE returns XY coordinates rather than XYZ coordinates and gives a 4% performance boost. - Removed helper code for
dplyr::bind_rowsas no longer required fordplyr 1.0.0
opentripplanner 0.2.2.0
CRAN release: 2020-06-06
- Changes to support
dplyr 1.0.0, package now needsvctrs 0.3.1 - Added timezone support to
otp_connect,otp_plan, andotp_isochronefixing issue #54, see docs for details. - Added
quietargument tootp_dl_jarandotp_dl_demo - Fixed error in advanced features vignette, issue #57
- Switch from dplyr to data.table, issue #60
opentripplanner 0.2.1.0
CRAN release: 2020-04-14
- 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
CRAN release: 2020-02-06
- Disabled CRAN tests that fail on solaris OS, due to different wording of error messages
